Answer:
1. C(s) + O₂(g) ⇄ CO₂(g)
2. ![K=\frac{[CO_{2}]}{[O_{2}]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BCO_%7B2%7D%5D%7D%7B%5BO_%7B2%7D%5D%7D)
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}]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BCO_%7B2%7D%5D%7D%7B%5BO_%7B2%7D%5D%7D)
Answer:
Dear, your answer is
solubility is affected by current concentration, mechanical disturbance, temperature and pressure. So the answers are:
- Increasing temperature decreases the solubility of gases.
- Stirring increases the solubility of solids.
- Increasing pressure increases the solubility of gases.
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.
Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
- There are over a hundred elements known to date.
- Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
- Examples are copper, gold, iron
- The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
- There are several millions of compounds known.
- They are usually represented by chemical formulae.
As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.
Answer:
for the process is -375 kJ
