Answer:
<u><em>1. The air boiled out of water as steam is rich in water vapor, </em></u><em><u>H₂O</u></em><u><em>(g)</em></u>
<u><em></em></u>
<u><em>2. Benzene reacts with hydrogen in the presence of nickel catalyst at 180°C to give cyclohexane.</em></u>
Explanation:
<em></em>
1. When water boils liquid water passes to gaseous phase.
Water in gaseous phase is named water vapor or steam.
This happens around 100ºC, depending on the atmospheric pressure.
The air that is around the boiling water will carry that steam, becomind an air rich in water vapor, H₂O(g)
2. Benzene has chemical formula C₆H₆.
It is a cyclic unsaturated hydrocarbon. Benzene contains 3 double bonds.
When unsaturated hydrocarbons are heated in the presence of nickel catalyst, the double bonds are broken, forming single bonds and adding the needed hydrogen to the chain: one to each carbon that had a double bond transformed into single bond.
Thus, the product of the catalytic hydrogenation of benzene, C₆H₆, is cyclohexane, C₆H₁₂

Answer:
D) 2 NOCl(g) ⇄ 2 NO(g) + Cl₂(g); Kp = 1.7 × 10⁻²
Explanation:
In order to compare the degree of decomposition of these reactions, we have to compare the equilibrium constant Kp. Kp is equal to the partial pressure of the products raised to their stoichiometric coefficients divided by the partial pressure of the reactants raised to their stoichiometric coefficients. The higher the Kp, the more products and fewer reactants at equilibrium. Among these reactions, D is the one that has the highest Kp, therefore the one experiencing the largest degree of decomposition.
Answer:
3. a) 1 atm,
4. 3 mol/L
Explanation:
3. Solubility 1 : solubility 2 = Pressure 1 : Pressure 2
6.0 g/L : 3.0 g/L = 2.0 atm : x atm
x = 3.0*2.0/ 6.0 = 1 atm
4. Molarity = 15 mol/5 L = 3 mol/L
