When the oxide of generic metal M is heated at 25.0 ∘ C , a negligible amount of M is produced. MO 2 ( s ) − ⇀ ↽ − M ( s ) + O 2
alex41 [277]

Answer:

1. C(s) + O₂(g) ⇄ CO₂(g)

2. K=\frac{[CO_{2}]}{[O_{2}]}

Explanation:

<em>When the oxide of generic metal M is heated at 25.0 °C, a negligible amount of M is produced. MO₂( s ) ⇄ M(s) + O₂(g) ΔG° = 290.2 kJ/mol.</em>

<em>1. When this reaction is coupled to the conversion of graphite to carbon dioxide, it becomes spontaneous. What is the chemical equation of this coupled process? Show that the reaction is in equilibrium. Include physical states and represent graphite as C(s).</em>

The chemical equation for the coupled reaction is:

C(s) + O₂(g) ⇄ CO₂(g)

<em>2. What is the thermodynamic equilibrium constant for the coupled reaction?</em>

The thermodynamic equilibrium constant (K) is the product of the concentration of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients. Only gases and aqueous species are included.

K=\frac{[CO_{2}]}{[O_{2}]}

Gallium (Ga) consists of two naturally occurring isotopes with masses of 68.926 and 70.925 amu. (a) How many protons and neutron
pav-90 [236]

Answer:

neutrons_{Ga-69}=38\\\\neutrons_{Ga-71}=40

Explanation:

Hello!

In this case, since isotopes of the same element have the same number of protons and electrons but different atomic mass, we can compute the number of neutrons by subtracting the number of protons to the atomic mass of the isotope; thus, for Ga-69 and Ga-71 (rounded up to whole numbers), we obtain:

neutrons_{Ga-69}=69-31=38\\\\neutrons_{Ga-71}=71-31=40

Best regards!
