Answer:
1.33L of gas
Explanation:
1 mole of Baking soda (NaHCO₃) reacts with acetic acid producing 1 mole of CO₂, water and sodium acetate, thus:
NaHCO₃ + CH₃COOH → NaCH₃COO + H₂O + CO₂
5g of NaHCO₃ (Molar mass: 84g/mol) are:
5g × (1mol / 84g) = 0.0595 moles of NaHCO₃ that produce 0.0595 moles of CO₂ -Moles of gas-.
If 1 mole of gas occupies 22.4L, 0.0595 moles occupy:
0.0595 moles gas × (22.4L / mol) = <em>1.33L of gas</em>
Freezing point depression is directly proportional to molality. So the compound to have the greatest effect will be the one that disassociates into the most ions = CaF2
Add up all the molar masses of the elements multiplied by the number of atoms each.
Molar mass of carbon = 12.01g
Molar mass of hydrogen = 1.01g
Molar mass of oxygen = 16g
9(12.01) + 8(1.01) + 4(16)
Molar mass of aspirin = 180.17g
Answer:
0.9875 mole O₂
Explanation:
Rxn => H₂ + ¹/₂O₂ => H₂O
from above reaction, 1 mol H₂ requires ¹/₂ mol O₂ then 1.975 mol H₂ requires ¹/₂(1.975 mol)O₂ or 0.9875 mol O₂.
The answer in C. Greenhouse Gases. Greenhouse Gases is caused by the trapped heart in the atmosphere harming us which we will always have. hope this helped
