You are watching: Which statement best describes the amount of catalyst that remains at the end of a reaction?
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.

Therefore, her friend is right due to the fact that the law of conservation of issue is not adhered to in this chemical equation.
Explanation:
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
Explanation:
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
Condensation _____. Is the readjust from fluid water to water vapor requires dust or various other tiny corpuscle happens an ext quickly in
Condensation is a process where a problem in the gas state is adjusted into a fluid state through removing heat to the system. The is the reverse of evaporation. Condensation is constantly associated v the water cycle. It is critical part that the water cycle since it is responsible because that the clouds come form.
