Answer: 1. 3.914 × ^10-4 | 2. 4.781 × ^10-1
Explanation:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
Use the formula PV=nRT
convert T into kelvin by 25+273
put in the values given and calculate n
Answer:
The <u>Law of Conservation of Energy</u> is the total energy of an isolated system that is remaining constant, it is conserved over time.
Explanation:
How does it relate to a chemical reaction: Chemical energy is converted to kinetic energy when a stick of dynamite explodes.
