Answer:
P(total) = 1110 mmHg
Explanation:
According to the Dalton law of partial pressure,
The pressure exerted by mixture of gases are equal to the sum of partial pressure of individual gases.
P(total) = P1 + P2 + P3+ .....+ Pn
Given data:
Sample A = 740 mmHg
Sample B = 740 mmHg
Sample C = 740 mmHg
Total pressure = ?
Solution:
<em>Sample A:</em>
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = 740 mmHg × 2L/4L
P₂ = 370 mmHg
<em>Sample B:</em>
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = 740 mmHg × 2L/4L
P₂ = 370 mmHg
<em>Sample C:</em>
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = 740 mmHg × 2L/4L
P₂ = 370 mmHg
Total pressure:
P(total) = P1 + P2 + P3
P(total) = 370 mmHg + 370 mmHg+ 370 mmHg
P(total) = 1110 mmHg

Answer:
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
Explanation:
In the first reaction (1) we have:
Silver nitrate and sodium chloride as the reactants. Then the products will be, silver chloride (s) and sodium nitrate.
We know that all the salts from the nitrate are soluble, so the chloride will react to the silver cation to make the precipitate, an insoluble salt.
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
For the second reaction (2), the reactants are:
Potassium phosphate and magnessium chloride
Phosphate salts are insoluble, except for the group 1. The same as chloride that makes soluble salts with the elements from the group 1.
The equation that makes the precipitate is.
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
