There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution while molality is expressed as the number of moles solute per mass of solution. Calculation is as follows:
(2 mol NaCl / L solution) ( 1 cm^3 / 1.35 g) ( 1000 L / 1 cm^3) (1000 g /kg) = 1.5 x 10^6 mol / kg solution
Reactions eventually stop. Generally the reason for this :
<u>C. One or more of the reactants has been used up.</u>
Explanation:
- A reaction is an action taken in response to something. If you're telling your parents that you want to move out, you'll see by their reaction that they're sad about it. A reaction is often a physical in nature.
- A chemical reaction describes the way a chemical behaves when combined with another substance.
- Reactants are substances initially present in a chemical reaction that are consumed during the reaction to make products. Some chemical reactions go to completion, resulting in all of the reactants becoming products. These reactions are said to be irreversible.
- All chemical reactions involve both reactants and products. Reactants are substances that start a chemical reaction, and products are substances that are produced in the reaction
- For example, burning methane in oxygen is irreversible.
- In a chemical reaction, reactants that are not used up when the reaction is finished are called excess reagents.
Answer:
6CO2 + 6H2O --> C6H12O6 + 6O2
C6H12O6 + O2 --> 6CO2 + 6H2O
Explanation:
The balanced form of both equations
Answer:

Explanation:
just finished the test
Answer:
2 mol of CO₂
Solution:
The reaction is as follow,
H₂CO + O₂ → CO₂ + H₂O
According to this equation,
1 mole of H₂CO produces = 1 mole of CO₂
So,
2 moles of H₂CO will produce = X moles of CO₂
Solving for X,
X = (2 mol × 1 mol) ÷ 1 mol
X = 2 mol of CO₂
