Answer: 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Explanation:
1) Chemical equation:
Formaldehyde + oxgyen → CO₂ + H₂O
H₂CO + O₂ → CO₂ + H₂O
2) That equation is already balanced
3) Mole ratios
1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O
4) Then, every mol of mol of H₂CO produces 1 mol of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Answer
E. 21.3mmHg is the right answer
Yes because the cold water has slower moving molecules.
Answer:
0.0917 mol Co(CrO₄)₃
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
37.3 g Co(CrO₄)₃
<u>Step 2: Identify Conversions</u>
Molar Mass of Co - 58.93 g/mol
Molar Mass of Cr - 52.00 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Co(CrO₄)₃ - 58.93 + 3(52.00) + 12(16.00) = 406.93 g/mol
<u>Step 3: Convert</u>
<u /> = 0.091662 mol Co(CrO₄)₃
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.091662 mol Co(CrO₄)₃ ≈ 0.0917 mol Co(CrO₄)₃
