Answer:

AgNO3 is soluble dissolves in water to give the Ag+ ion and the NO3- ion

Pb(C2H3O2)2 is soluble in water to give the Pb2+ ion and the CH3COO- ion

KNO3 is soluble in water to give K+ ion and the NO3- ion

(NH4)2S is soluble in water to give the NH4+ ion and the S2- ion

Explanation:

This question requires a knowledge of a few solubility rules

All nitrates are soluble in water

All group I salts are soluble in water

All ammonium salts are soluble in water

All ethanoates are soluble in water except silver ethanoate

Answer:

According to the solubility rules:

<u>1. Silver nitrate</u>: AgNO₃ is soluble.

Reason: Nitrates (NO₃⁻) are soluble.

AgNO₃ (aq) → Ag⁺(aq) + NO₃⁻(aq)

<u>Ions present</u>: silver ion (Ag⁺) and nitrate ion (NO₃⁻)

<u>2. Lead(II) acetate:</u> Pb(C₂H₃O₂)₂ is soluble.

Reason: Acetates (C₂H₃O₂⁻) are soluble

Pb(C₂H₃O₂)₂ → Pb²⁺(aq) + 2 CH₃COO⁻(aq)

<u>Ions present</u>: lead(II) ion (Pb²⁺) and two acetate ions (CH₃COO⁻)

<u>3. Potassium nitrate</u>: KNO₃ is soluble.

Reason: Nitrates (NO₃⁻) are soluble and group-1 ions such as K⁺ are soluble.

KNO₃ (aq) → K⁺(aq) + NO₃⁻(aq)

<u>Ions present:</u> potassium ion (K⁺) and nitrate ion (NO₃⁻)

<u>4. Ammonium sulfide: </u>(NH₄)₂S is soluble.

Reason: Ammonium (NH₄⁺) ions are soluble

(NH₄)₂S (aq) → 2 NH₄⁺(aq) + S²⁻(aq)

<u>Ions present:</u> two ammonium ions (NH₄⁺) and sulphide ion (S²⁻)

suter [353]

The reaction of removing CO2 using LiOH is the following:

2 LiOH + CO2 -----> Li2CO3 + H2O

By solving the amount of CO2 the LiOH can scrub:

(3.50 × 10^4 g LiOH) (1 mol LiOH/ 24 g LiOH) ( 1 mol CO2 / 2 mol LiOH) ( 44 g CO2 /1 mol CO2) = 32, 083.33 g CO2 it can scrub

<span>Since number of astronaut = 32, 083.33 g / 9 (8.8 × 10^2) = 4 astronaut</span>
