Which statement best describes the amount of catalyst that remains at the end of a reaction?
Ivenika [448]
I believe the correct answer is C. The amount of catalyst is the same at the end as at the beginning of the reaction. Catalysts can't be consumed by the reaction thus is not D.

Which equation is a decomposition reaction? Li2CO3 Right arrow. Li2O + CO2 Zn + HCl Right arrow. ZnCl2 + H2 Na2O + CO2 Right arr
Dmitrij [34]

Answer:

Li₂CO₃ ⇒ Li₂O + CO₂ is a decomposition reaction.

Explanation:

In a decomposition reaction, a single substance decomposes, producing two or more different substances. In other words, in this type of reaction two or more substances are formed from a compound. The atoms that form a compound separate to give the products according to the formula:

AB → A + B

It can occur spontaneously, or be aided by a catalyst, heat, or electrolysis.

In this case:

Li₂CO₃ ⇒ Li₂O + CO₂ It is a type of chemical reaction in which a single compound decomposes into two or more compounds. So it is a decomposition reaction.

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide (NO) gas, 2.61 atm chlorine (C12) gas, and 8.64 atm nitrosyl c
lys-0071 [83]

Answer:

\Delta _rG=2832.2J/mol

Explanation:

Hello,

In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:

K=\frac{p_{NOCl}^2}{p_{NO}^2p_{Cl_2}} =\frac{8.64^2}{9.47^2*2.61}=0.319

Hence the Gibbs free energy:

\Delta _rG=-RTlog(K)=-8.314\frac{J}{mol*K}*298.15K*ln(0.319)\\\\\Delta _rG=2832.2J/mol

Best regards.
