Let suppose the Gas is acting Ideally, Then According to Ideal Gas Equation,
P V = n R T
Solving for P,
P = n R T / V ----- (1)
Data Given;
Moles = n = 1.20 mol
Volume = V = 4 L
Temperature = T = 30 + 273 = 303 K
Gas Constant = R = 0.08206 atm.L.mol⁻¹.K⁻¹
Putting Values in Eq.1,
P = (1.20 mol × 0.08206 atm.L.mol⁻¹.K⁻¹ × 303 K) ÷ 4 L
P = 7.45 atm
No chemical bonding take place.
And the elements or compounds in the mixtures have no definite proportions.
Answer:

Potassium 19 8
Calcium
Answer:
2H⁺ + 2e → H₂.
Zn → Zn²⁺ + 2e.
Explanation:
- The reaction includes two half-reactions:
<em>The reduction reaction:</em>
<em>2H⁺ + 2e → H₂.</em>
- 2.0 moles of hydrogen ions is reduced by 2 electrons to produce 1.0 mole of hydrogen gas.
<em>The oxidation reaction:</em>
<em>Zn → Zn²⁺ + 2e.</em>
- 1.0 mole of Zn metal is oxidized to Zn²⁺ and releases 2 electrons.
- <em>The overall reaction will be:</em>
<em>Zn + 2H⁺ → Zn²⁺ + H₂.</em>
