Answer:
Explanation:
Causes of Greenhouse Effect
- Burning of Fossil Fuels. Fossil fuels are an important part of our lives.
- Deforestation. Plants and trees take in carbon dioxide and release oxygen.
- Industrial Waste and Landfills.
- Depletion of Ozone Layer.
- Acidification of Water Bodies.
H₂ + CO₂ ⇄ CO + H₂O
1 mol H₂ - 1 mol H₂O
x mol H₂ - 30.6 mol H₂O
x=30.6*1/1=30.6 mol (<span>theoretically)</span>
Ca ionises into Ca^2+. Ca^2+ will be attracted to O^2- ions in the water, since opposite charges attract. (Hydrogen in water forms H^+)
Answer:
33.21% is the right answer.
Explanation:
0.04720 L * 0.02240 mol / L = 1.0573*10-3
mol Fe+2 = 1.0573* 10-3 mol = 5.2864*10-3
mass of Fe= 5.2864 * 10-3 = 0.29522g
% of Fe in sample = 0.29522 g Fe / 0.8890 g of sample * 100 = 33.21%
