Answer:
[Al³⁺] = 1.62 M
[SO₄²⁻] = 2.43 M
Explanation:
Step 1: Given data
Molar concentration of Al₂(SO₄)₃: 0.811 M
Step 2: Write the reaction for the ionization of Al₂(SO₄)₃
Al₂(SO₄)₃(aq) ⇒ 2 Al³⁺(aq) + 3 SO₄²⁻(aq)
Step 3: Calculate the molar concentration of Al³⁺
The molar ratio of Al₂(SO₄)₃ to Al³⁺ is 1:2. The molarity of Al³⁺ is 2/1 × 0.811 M = 1.62 M.
Step 4: Calculate the molar concentration of SO₄²⁻
The molar ratio of Al₂(SO₄)₃ to SO₄²⁻ is 1:3. The molarity of SO₄²⁻ is 3/1 × 0.811 M = 2.43 M
Answer:
1363.2 kilocalories
Explanation:
Heat up the ice ==> melt the ice to water ==> heat the water ==> vaporize the water to steam ==> heat the stem 52 degrees to 152
1.81 kg * (spec heat of ice * 19 +* heat of fusion of water + specific heat of water *100 + heat of vaporization of water + specific heat of steam* 52)
1810 g * ( .50 cal/g -C * 19 C + 79.7 cal / g + 1 cal/g-C *100C + 539 cal/g + .48 cal/g * 52 C ) =<u> 1 363 219.6 calories</u>
