Answer: It shows whether the reaction is exothermic or endothermic.
Explanation:
- If the potential energy of the products is greater than that of the reactants, then the reaction is exothermic.
- If the potential energy of the reactants is greater than that of the products, then the reaction is endothermic.
Answer:
the land is heated through radiant energy,
Explanation:
Answer:
= 1.806 × 10^25 molecules.
Explanation:
1 mole of CO2 contains 6.02 × 10^23 molecules
30 moles of CO2 will contain ( 30 × 6.02 × 10^23 )
= 1.806 × 10^25 molecules.
Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
The student stirs it because he wants the reaction to take place more quickly.
