To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water. Ex. 2CH4 + 3O2 → 2CO + 4H2O The amount of oxygen present and the temperature determine whether the reaction is complete or incomplete.

At dynamic equilibrium, the concentration of ice and water has been equal. Thus, option D is correct.

The equilibrium state can be given as the condition when the reactant and the product in the chemical reaction have been in equal amount.

In the condition when the water has bee kept in the freezer, the water will condense at the freezing temperature and will be converted to ice. The water there has been the reactant while the ice has been the product.

According to the law of equilibrium, at the equilibrium there has been equal concentration of reactant and products. Thus, at dynamic equilibrium, the concentration of ice and water has been equal. Thus, option D is correct.

Hello..!

There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.

\( \sf \red {\underline{ \underline{Explantation:}}}\)

Ions with a positive charge are known as cations. Those that are negatively charged are called anions.

¿Doubts? in the comments Greetings.

The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.

Explanation:

The rat smells the food or sees the food it goes towards the food to eat it.

Answer:

B

Explanation:

since the farther you go out in the atmosphere the temperature decrease and the air pressure drops

Answer:

1. A = 1; 2, B = 2; 3. C = 1; 4. D = 2; 5. 1 mol SnO₂, 1 mol;

6. SnO₂ and H₂; 7. Sn and H₂O; 8. Endothermic,

Explanation:

Often, the best way to start is to balance all atoms other than O and H, then balance O, then balance H.

1. Put a 1 in front of the most complicated-looking formula (SnO₂):

1SnO₂ + H₂ ⟶ Sn + H₂O

2. Balance Sn:

We have fixed 1 Sn on the left. We need only 1 Sn on the right. Put a 1 in front of Sn to fix it.

1SnO₂ + H₂ ⟶ 1Sn + H₂O

3. Balance O:

We have fixed 2 O on the left. We need 2 O on the right. Put a 2 in front of H₂O.

1SnO₂ + H₂ ⟶ 1Sn + 2H₂O

4. Balance H

We have fixed 4H on the right. We need 4H on the left. Put a 4 in froth of H₂.

1SnO₂ + 2H₂ ⟶ 1Sn + 2H₂O

Every formula now has a coefficient. The equation should be balanced.

5. Check that atoms balance:

\(\begin{array}{ccc}\textbf{Atom} & \textbf{On the left} & \textbf{On the right}\\\text{Sn} & 1 &1\\\text{O} & 2 & 2\\\text{H} & 4 & 4\\\end{array}\)

It checks.

The balanced equation is

SnO₂ + 2H₂ ⟶ Sn + 2H₂O

6. Moles of SnO₂

According to the balanced equation,

1 mol of SnO₂ reacts with 2 mol of H₂.

The balanced equation represents 1 mol of SnO₂.

7. The reactants — on the left of the reaction arrow — are SnO₂ and H₂.

8. The products — on the right of the reaction arrow — are Sn and H₂O.

9. The energy is on the reactant side of the equation, so it is being added to the system.

The reaction is endothermic.

The major disadvantage of using charts and graphs is that these aids may oversimplify data, which can provide a misleading view of the data. Attempting to correct this can make charts overly complex, which can make their value in aiding a presentation less useful.

Explanation:

hope it helps if did then mark me the briliantest

The disadvantages of using a graph to communicate data is data can be misrepresented, not as precise. Therefore, option A is correct.

Disadvantages of using a graph include the need for further written or verbal explanation and the ease with which they can be misrepresented.

Charts have the potential to simplify the data, which might obscure some of its more challenging features. A chart is more aesthetically pleasing and more effective at highlighting the important parts of the data, since it emphasizes those features.

The cost of human labor and resources, the process of choosing the best graphical and tabular representation of data, the complexity of the visualizing data's design, and the possibility of human bias are the usual drawbacks of graphical representation of data.

Thus, option A is correct.

Answer:

When an organism use chemical energy to move, some of it is lost as metabolic heat.

The term chemical energy is defined as the energy which is stored in the bonds of chemical compounds. It is given in the chemical reaction and mostly produces heat as a by-product, known as an exothermic reaction.

Energy changes as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are taken by organisms from the next level.

Thus, Metabolic heat is lost when an organism uses chemical energy to move.
