A typical level of sodium in blood is 3.24 mg/mL. What is the millimolar concentration of sodium in blood?

Answer:

2.7 moles of Fe₂O₃ is the maximum amount that can be produced. Iron is the limiting reactant.

Explanation:

The balanced reaction is:

4 Fe + 3 O₂ → 2 Fe₂O₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

You can use a simple rule of three as follows: if by stoichiometry 4 moles of Fe reacts with 3 moles of O₂, how much moles of Fe will be needed if 4.7 moles of O₂ react?

\(moles of Fe =\frac{4. moles of Fe*4.7 moles of O_{2}}{3 moles of O_{2} }\)

moles of O₂= 6.27

But 6.27 moles of Fe are not available, 5.4 moles are available. Since you have less moles than you need to react with 4.7 moles of O₂, iron Fe will be the limiting reagent.

So you can use a simple rule of three as follows: if by stoichiometry 4 moles of Fe produce 2 moles of Fe₂O₃, how many moles of Fe₂O₃ will be produced if 5.4 moles of Fe react?

\(moles of Fe_{2}O_{3}=\frac{5.4 moles of Fe*2 moles of Fe_{2} O_{3} }{4 moles of Fe}\)

moles of Fe₂O₃= 2.7 moles

Then:

2.7 moles of Fe₂O₃ is the maximum amount that can be produced. Iron is the limiting reactant.

To produce ClO⁻ and ClO₃⁻, the mole ratio of Cl₂ is 1 :2 and 1 : 2.

The reaction for disproportionate of Cl₂ in basic medium to produce ClO⁻ and ClO₃⁻ is:

Cl₂ (g) + 2OH⁻ (aq) → Cl⁻(aq) + ClO⁻ (aq) + H₂O(l)

3Cl₂ (g) + 6OH⁻ (aq) → 5Cl⁻ (aq) + ClO₃⁻ (aq) + 3H₂O (l)

When ratio of Cl₂ is 1: 2 then ClO⁻ is produced. Ratio is 3 : 6 then ClO₃⁻ is produced.

To produce ClO⁻ ; the mole ratio of Cl₂

= \(\frac{1}{2}\)

= 1 : 2

To produces ClO₃⁻ ; mole ratio of Cl₂

= \(\frac{3}{6}\)

= 1 : 2

Thus from the above conclusion we can say that To produce ClO⁻ and ClO₃⁻, the mole ratio of Cl₂ is 1 :2 and 1 : 2.

The temperature changes of the propane as it is throttled from its saturation pressure to the ambient pressure depend on the specific condition and the pressure changes that are involved. However, propane is gas indeed.

Saturation pressure is the pressure at which a substance changes phase into a gas phase at a specific temperature. In other words, it is the pressure at which vaporization starts to occur to the substance. When a substance is heated at constant pressure, its temperature will increase until it reaches a boiling point and begin to vaporize. At this point, the saturation pressure is reached, further increasing the temperature.

For propane, the saturation pressure when the temperature is 20°C is around 8.5 atm.

To prepare 2.40 L of 0.500 M NaOH solution from an 8.25 M NaOH solution, you need to determine the volume of the concentrated solution required.

You can use the dilution equation:
M1 × V1 = M2 × V2
where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
Here, M1 = 8.25 M, M2 = 0.500 M, and V2 = 2.40 L. You need to solve for V1:
8.25 M × V1 = 0.500 M × 2.40 L

Rearrange the equation to find V1:
V1 = (0.500 M × 2.40 L) / 8.25 M
V1 = 1.20 L / 8.25
V1 ≈ 0.145 L or 145 mL

So, to prepare 2.40 L of 0.500 M NaOH solution, you must dilute 145 mL of 8.25 M NaOH solution.

The concentration of the nitrate ion, NO₃¯ in the solution given the data is 0.0216 M

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

Mole = mass / molar mass

Mole of Al(NO₃)₃ = 0.6 / 213

Mole of Al(NO₃)₃ = 0.0028 mole

Molarity = mole / Volume

Molarity of Al(NO₃)₃ = 0.0028 / 0.39

Molarity of Al(NO₃)₃ = 0.0072 M

Dissociation equation

Al(NO₃)₃(aq) <=> Al³⁺(aq) + 3NO₃¯(aq)

From the balanced equation above,

1 mole of Al(NO₃)₃ contains 3 moles of NO₃¯

Therefore,

0.0072 M Al(NO₃)₃ will contain = 0.0072 × 3 = 0.0216 M NO₃¯

The approximate Hrxn for the hydrogen combustion reaction can be +520 kJ/mol.

To calculate the approximate Hrxn for the given reaction, we need to determine the energy required to break the bonds in the reactants and the energy released when new bonds are formed in the products.

Reactants;

2 H-H bonds (in 2 H₂ molecules) = 2 x 430 kJ/mol

1 O=O bond (in 1 O₂ molecule) = 1 x 500 kJ/mol

Total energy required to break bonds in reactants = (2 x 430 kJ/mol) + (1 x 500 kJ/mol) = 1360 kJ/mol

Products;

4 O-H bonds (in 2 H₂O molecules) = 4 x 470 kJ/mol

Total energy released when new bonds are formed in products = (4 x 470 kJ/mol) = 1880 kJ/mol

Therefore, the approximate Hrxn for the hydrogen combustion reaction can be calculated as follows;

Hrxn = energy required to break bonds in reactants - energy released when new bonds are formed in products

= -1360 kJ/mol + 1880 kJ/mol

= +520 kJ/mol

Since the value of Hrxn is positive, this indicates that the reaction will be endothermic.

This question is incomplete. However, the completed question is below

A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experimental set-up is shown below: An inverted glass jar is shown. Small circles representing foam balls are shown inside the jar. A stretched balloon is shown tied at the mouth of the jar. A string is shown drawn out from the middle of the stretched balloon. A hand is shown pulling the drawn out string. The teacher pulled the string attached to the stretched balloon, first slowly, then fast, and finally vigorously. Which of the following is most likely correct about the pulling of the string and the corresponding state of matter being represented? (a) Gas is represented when pulled fast, solid when pulled slowly, liquid when pulled vigorously. (b) Gas is represented when pulled slowly, liquid when pulled fast, solid when pulled vigorously. (c) Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously. (d) Solid is represented when pulled vigorously, liquid when pulled fast, gas when pulled slowly.

The correct answer is C

Explanation:

These question has to do with the "freedom" of particles in each state of matter. In solids, the particles are compact and do not move freely within the solid molecule hence the reason for the definite shape of solid. The particles of liquids move more freely than solid but not as much as gases, hence the reason for there free flowing nature. Particles of gases move more fast and rapidly; colliding against one another and the wall of the container.

From the above description, it can be deduced that to illustrate these particles the teacher will have to represent the particles of the solid as been moved slowly, particles of the liquid will be pulled fast and that of gas will be pulled vigorously using balloons. Thus, the correct option is C

Answer:

the correct answer is c!

Explanation:

Solid is represented when pulled slowly, liquid when pulled fast, gas when pulled vigorously.

Explanation:

The symbol for sodium is Na.  The term "sodium ion" assumes that the reader knows that sodium's single 3s electron is susceptible to theft by any nearby element that has a high electron affinity.  Sodium's ionization energy is low, allowing the 3s electron to move elsewhere and leave behinf a positively charged Na^+ atom.

The percent yield for each compound:

a) For NaHCO3: 100%
b) For Na2CO3: 126.2%
c) For CO2: 100%
d) For H2O: 0%

To find the percent yield, we first need to determine the theoretical yield and actual yield for each compound. The theoretical yield is the amount of product that would be obtained if the reaction proceeded perfectly, while the actual yield is the amount of product obtained in reality.

Let's calculate the theoretical yield for each compound:

a) NaHCO3(s): Since 3.08 g of NaHCO3 is given, the theoretical yield of NaHCO3 would also be 3.08 g.

b) Na2CO3(s): The given problem states that 1.04 g of Na2CO3 is obtained. However, since Na2CO3 is formed from NaHCO3, we need to consider the molar mass ratio between NaHCO3 and Na2CO3. The molar mass of NaHCO3 is 84 g/mol, and the molar mass of Na2CO3 is 106 g/mol. Using this ratio, we can calculate the theoretical yield of Na2CO3:

(1.04 g Na2CO3) × (84 g NaHCO3 / 106 g Na2CO3) = 0.824 g NaHCO3

c) CO2(g): CO2 is produced during the decomposition of NaHCO3, and it is a gas. Therefore, we need to convert the mass of NaHCO3 to moles and then use the balanced chemical equation to find the moles of CO2 produced. The balanced equation for the decomposition of NaHCO3 is:

2 NaHCO3(s) -> Na2CO3(s) + CO2(g) + H2O(g)
The molar mass of NaHCO3 is 84 g/mol.

(3.08 g NaHCO3) / (84 g/mol NaHCO3) = 0.0367 mol NaHCO3
According to the balanced equation, 1 mole of NaHCO3 produces 1 mole of CO2. Therefore, the theoretical yield of CO2 is also 0.0367 mol.

d) H2O(g): Similarly, we can use the balanced equation to determine the theoretical yield of water. According to the equation, 1 mole of NaHCO3 produces 1 mole of H2O. Therefore, the theoretical yield of H2O is 0.0367 mol.

Now, let's calculate the percent yield for each compound:

Percent yield = (Actual yield / Theoretical yield) × 100

a) For NaHCO3:
Percent yield = (3.08 g / 3.08 g) × 100 = 100%

b) For Na2CO3:
Percent yield = (1.04 g / 0.824 g) × 100 = 126.2%

c) For CO2:
Percent yield = (0.0367 mol / 0.0367 mol) × 100 = 100%

d) For H2O:
Percent yield = (0 mol / 0.0367 mol) × 100 = 0%

To summarize, the percent yield for NaHCO3 is 100%, for Na2CO3 is 126.2%, for CO2 is 100%, and for H2O is 0%.

Percentage composition of oxygen = (80/134) * 100% = 59.7%.

Answer:

C) Reaction with dilute action

Explanation:

Metals are good conductors of electricity and heat.

Non-metals are insulators that don't allow heat and electricity to pass through them. Hence, non-metals are bad conductors of electricity and heat.

To calculate the percent composition by mass of carbon in \(C_6H_{100}\), we need to determine the molar mass of carbon in the compound and divide it by the molar mass of the entire compound.

The balanced equation given indicates that for every 1 mole of \(C_6H_{100}\) burned, 6 moles of \(CO_2\) are produced. Using the molar masses of carbon and  \(C_6H_{100}\) , we can calculate the percent composition by mass of carbon.

The molar mass of carbon (C) is 12.01 g/mol. The molar mass of  \(C_6H_{100}\) can be calculated as follows:

(6 × 12.01 g/mol) + (1 × 1.01 g/mol) + (10 × 16.00 g/mol) = 162.10 g/mol.

To determine the percent composition by mass of carbon in  \(C_6H_{100}\) , we need to find the mass of carbon in 1 mole of  \(C_6H_{100}\) . Since there are 6 carbon atoms in the compound, the mass of carbon is:

(6 × 12.01 g/mol) = 72.06 g.

Now we can calculate the percent composition by mass of carbon:

(72.06 g / 162.10 g) × 100% ≈ 44.5%.

Therefore, the percent composition by mass of carbon in  \(C_6H_{100}\) is approximately 44.5%.

The hypothesis was supported by the results of the experiment:

The correct option is II only.

The strength of the electromagnet rises with the number of turns in the coil.

This is due to the fact that as the coil "cuts" through the magnetic field, the sum of the individual emf s created by each turn increases with the number of coils turns.

The relative speed between the coil and magnet, as well as the magnet's strength, are additional elements that influence the strength of the induced current in a dynamo in addition to the number of coils. The intensity of the generated current increases with magnet strength and relative speed.
