thedesigningfairy.com is: C) The lot of catalyst is the exact same at the finish as at the start of the reaction.
A catalyst is a chemical varieties that is existing at the start of a reaction and reappears at the end.
An intermediate forms throughout the reaction and disappears prior to the end.
Catalysis is the boost in the rate of a chemistry reaction because of the participation of an additional substance dubbed a catalyst.
Reactions occur much faster with a catalyst because they require less activation energy.

A chemist determined by measurements that 0.015 moles of gold participated in a chemical reaction. Calculation the massive of yellow th
thedesigningfairy.com: The fixed of yellow participated in the chemistry reaction is 2.95 grams
To calculate the variety of moles, we usage the equation:
Molar massive of yellow = 197 g/mol
Moles of yellow participated in the reaction = 0.015 moles
Putting worths in above equation, we get:
Hence, the mass of yellow participated in the chemistry reaction is 2.95 grams
