Answer:
✓no change in the composition of the platinum could be detected
Explanation:
1 gram of AGNO3 is 169,87 g/mol
2.5 mole = 2.5×16987
= 42467
Answer:
11.6 mol O₂
Explanation:
- C₇H₁₆ + 11 O₂ → 7 CO₂ + 8 H₂O
In order to solve this problem we need to <u>convert moles of carbon dioxide (CO₂) into moles of oxygen gas (O₂)</u>. To do so we'll use a conversion factor containing the <em>stoichiometric coefficients</em> of the balanced reaction:
- 7.4 mol CO₂ * = 11.6 mol O₂
