What is the molarity of aqueous silver nitrate if 50.0 mL of AgNO3 reacts with 25.0 mL of 0.100 M K2CrO4?
2 AgNO3(aq) + K2CrO4(aq) → Ag2CrO4(s) + 2 KNO3(aq)

Answers

Answer 1

The molarity of aqueous silver nitrate is 0.050 M.

In order to find the molarity of AgNO₃, we first need to use stoichiometry to find the number of moles of K₂CrO₄ used in the reaction. We can use the equation:

2 AgNO₃(aq) + K₂CrO₄(aq) → Ag₂CrO₄(s) + 2 KNO₃(aq)

From the equation, we can see that the stoichiometric ratio of AgNO₃ to K₂CrO₄ is 2:1. Therefore, the number of moles of K₂CrO₄ used in the reaction can be calculated as follows:

25.0 mL × 0.100 mol/L = 0.00250 mol K₂CrO₄

Since the stoichiometric ratio of AgNO₃ to K₂CrO₄ is 2:1, the number of moles of AgNO₃ used in the reaction is twice that of K₂CrO₄, or:

0.00250 mol K₂CrO₄ × 2 mol AgNO₃/1 mol K₂CrO₄ = 0.00500 mol AgNO₃

Finally, we can calculate the molarity of AgNO₃ using the formula:

Molarity = moles of solute ÷ volume of solution in liters

Molarity = 0.00500 mol ÷ 0.050 L = 0.050 M

Because increased temperature increases fluidity, the bacterium shoulddecrease the length of fatty acid tails on membrane lipidsC.Because increased temperature decreases fluidity, the bacterium shoulddecrease the length of fatty acid tails on membrane lipidsO Because increased temperature increases fluidity, the bacterium shouldincrease the length of fatty acid tails on membrane lipids

Answers

Option B is the correct answer. If a bacterium adapted to a cold environment were moved to a much warmer environment, the increased temperature would increase the fluidity of the membrane.

The fluidity of the bacterial membrane is critical for its function, and it depends on the composition of the membrane lipids. At low temperatures, the membrane lipids of the bacterium from a cold environment have more unsaturated fatty acids, which increase the fluidity of the membrane to maintain its function. In contrast, at high temperatures, the membrane lipids of the bacterium from a warm environment have more saturated fatty acids, which decrease the fluidity of the membrane.

If a bacterium adapted to a cold environment were moved to a much warmer environment, the increased temperature would increase the fluidity of the membrane. To maintain the integrity and function of the membrane, the bacterium must decrease the fluidity of the membrane. The bacterium can do this by decreasing the length of the fatty acid tails on the membrane lipids. Shorter fatty acid tails result in fewer interactions between the lipid molecules, which decreases the fluidity of the membrane. Therefore, option B is the correct answer.

Answers

The percent change in volume is 21 %.

given that :

temperature , T1 = 273 -28 = 245 K

temperature , T2 = 273 + 9 = 282 K

pressure P1 = P

pressure P2 = P - O.O5 P = 0.95 P

Volume V1 = V

volume V2 = ?

using ideal gas equation , we get :

P1 V1 / T1 = P2 V2 / T2

V2 = (P1 V1 T2 ) / P2 T1

V2 = ( P × V × 282 ) / ( 0.95 P × 245 P )

V2 = 1.211 V

change in volume is given as = V2 - V1

                                                 =  1.211 V - V

                                                 = 0.211 V

Percent change in volume is = (0.21 V)) / V ) × 100 %

a ground state hydrogen atom absorbs a photon of light having a wavelength of 92.6 nm. what is the final state of the hydrogen atom?

Answers

When a ground state hydrogen atom absorbs a photon of light having a wavelength of 92.6 nm, the final state of the hydrogen atom is the excited state.

The hydrogen atom has only one electron, which is located in the ground state or the first energy level. When a photon of light of 92.6 nm wavelength is absorbed, the electron gains energy and jumps to the higher energy level, which is the second energy level (n = 2).

Thus, the final state of the hydrogen atom is the excited state or the second energy level. The energy absorbed by the electron is equal to the energy of the photon. The energy of a photon is given by the formula: Energy of a photon = hc/λwhere,h = Planck's constant = 6.626 x 10⁻³⁴ J.s

c = speed of light = 3 x 10⁸ m/s λ = wavelength of the photon

Substituting the given values, we get

Energy of a photon = (6.626 x 10⁻³⁴ J.s x 3 x 10⁸ m/s) / (92.6 x 10⁻⁹ m)

Energy of a photon = 2.14 x 10⁻¹⁸ J. The energy absorbed by the electron is equal to the energy difference between the two energy levels.

The energy of an electron in the nth energy level of the hydrogen atom is given by the formula: E_n = (-2.18 x 10⁻¹⁸ J) / n² where, E_n = energy of electron in nth energy level

Substituting n = 1 (ground state), we get: E₁ = (-2.18 x 10⁻¹⁸ J) / (1)²   E₁= -2.18 x 10⁻¹⁸ J

Substituting n = 2 (excited state), we get: E₂ = (-2.18 x 10⁻¹⁸ J) / (2)²  E₂ = -0.545 x 10⁻¹⁸ J

The energy absorbed by the electron is the difference between the energy of the electron in the excited state and the energy of the electron in the ground state.

ΔE = E₂ - E₁

ΔE = (-0.545 x 10⁻¹⁸ J) - (-2.18 x 10⁻¹⁸ J)ΔE = 1.64 x 10⁻¹⁸ J

Since the electron gains energy, the energy absorbed by the electron is positive. Therefore, the final state of the hydrogen atom is the excited state.

Mrs. Webb placed a cup containing 10.0 g of water into a beaker, then placed 2.0 g of calcium carbide, CaC₂ into the H₂O. The reaction produced flammable ethyne (C₂H₂) gas an calcium hydroxide.
a. Write the balanced equation for the reaction. CaC₂+ H₂O → C₂ H₂ + Ca(OH)₂
b. How many L of ethyne (at STP) can form?​

Answers

Explanation:

To determine how many liters of ethyne (C₂H₂) can form at STP, we need to use stoichiometry and the ideal gas law.

First, let's determine the number of moles of CaC₂ and H₂O that reacted. From the given information, we know that the mass of water is 10.0 g and the mass of CaC₂ is 2.0 g. We can use the molar masses of CaC₂ (64.10 g/mol) and H₂O (18.02 g/mol) to convert the masses to moles:

moles of CaC₂ = 2.0 g / 64.10 g/mol = 0.0312 mol

moles of H₂O = 10.0 g / 18.02 g/mol = 0.555 mol

Next, we need to determine the limiting reactant to find out how many moles of ethyne can form. To do this, we compare the mole ratio of CaC₂ to H₂O in the balanced equation:

CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂

1 2

For every 1 mole of CaC₂, we need 2 moles of H₂O to react. The moles of H₂O we have (0.555 mol) are more than enough to react with the moles of CaC₂ we have (0.0312 mol). Therefore, CaC₂ is the limiting reactant.

Now we can use the mole ratio of CaC₂ to C₂H₂ in the balanced equation to find the moles of C₂H₂ that can form:

CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂

1 1

1 mole of CaC₂ produces 1 mole of C₂H₂. Therefore, the moles of C₂H₂ that can form is also 0.0312 mol.

Finally, we can use the ideal gas law to find the volume of C₂H₂ at STP. The ideal gas law is PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. At STP, the pressure is 1 atm and the temperature is 273 K.

Plugging in the values, we get:

V = (nRT) / P

V = (0.0312 mol)(0.0821 L·atm/mol·K)(273 K) / 1 atm

V = 0.738 L

Therefore, the volume of C₂H₂ that can form at STP is 0.738 L.

what volume of methane gas, ch4, reacts to give 5.00 ml of carbon dioxide gas? (assume temperature and pressure remain constant.) ch4(g) o2(g) spark co2(g) h2o(g)

Answers

Carbon dioxide is produced when 5 mL of methane gas interacts.

Methane, a hydrocarbon, is the primary component of natural gas. Methane has an effect on the climate and temperature of the earth because it is a greenhouse gas (GHG). Methane is released into the atmosphere through a variety of natural and anthropogenic (caused by humans) sources.

Methane is non-toxic and safe to breathe in small amounts, but if it is allowed to replace air in large quantities, the absence of oxygen could result in suffocation.

\(CH_{4}(g) + 2O_{2} \rightarrow CO_{2} + 2H_{2}O(g)\)

1 volume of \(CH_{4}\) = 1 volume of \(CO_{2}\)

5 ml of \(CH_{4}\) = 1 × 5 mL CO2

                    = 5 mL CO2

So, volume of methane = 5mL

The solution to the equation and value of variable 21(3d - 4) + 100 = 58 is d = 2/3.

Solve the equation 21(3d - 4) + 100 = 58, we can begin by simplifying and isolating the variable:

21(3d - 4) + 100 = 58

Distribute 21 to the terms inside the parentheses:

63d - 84 + 100 = 58

Combine like terms:

63d + 16 = 58

Subtract 16 from both sides:

63d = 42

Divide both sides by 63:

d = 42/63

Simplifying the fraction gives:

d = 2/3

The solution to the equation is d = 2/3.

The solution to the equation 21(3d - 4) + 100 = 58 is d = 2/3. By simplifying the equation, we find that dividing both sides by 63 results in the solution of d = 2/3, which satisfies the original equation.
