Answer:
Energy is transferred when atoms are rearranged.
Explanation:
Answer:
- Volume of the solution will increase.
- Molarity will decrease.
Explanation:
Hello,
In this case, for molarity, unit of concentration relating the moles of solute and volume of solution, we have:
Hence, since the given molarity is 0.70M, we first shall infer that by adding more water, that for sure is the solvent, the volume of the solution will increase which will be the first change. Moreover, since the volume and the molarity are in an inversely proportional relationship, as the volume increases the molarity decreases, which is the other change. In addition to the aforementioned statements, the moles of the solute are not modified as just water is added.
Best regards.
Answer:
Information that must be specified is the temperature of the solution,Amount of solute,Amount of solvent,and Identity of the solvent.
Explanation:
<u>Answer:</u> The correct answer is Option a.
<u>Explanation:</u>
The reaction between sodium thiosulfate and nitric acid produces a number of products. The balanced chemical equation for the reaction of two follows:
By Stoichiometry of the reaction:
1 mole of sodium thiosulfate reacts with 2 moles of nitric acid to produce 2 moles of sodium nitrate, 1 mole of water, 1 moles of sulfur dioxide and 1 mole of solid sulfur.
Hence, the correct answer is Option a.
