Answer:

8. the answer is B.

9. the answer is A.

Explanation:

Hello!

8. In this case, by bearing to mind that the limiting reactant is always completely consumed and the excess one remain as a leftover at the end of the reaction, we can also infer that as all the limiting reactant is consumed, it must determine the maximum amount of product as the excess reactant will hypothetically produce a greater mass than expected; thus, the answer to this question is B.

9. In this case, since the mole ratio of oxygen to water is 1:2, the following proportional factor is used to calculate the produced mass of water:

3molO_2*\frac{2molH_2O}{1molO_2}=6molH_2O

Thus, the answer is this case is A.

Best regards!

Charle's Law
Setler [38]

Convert temperature to Kelvin

  • 225°C=498K
  • 127°C=400K

Convert vol to L

  • 400mL=0.4L

Apply Charles law

  • V1T_2=V2T_1
  • 0.4(400)=498V_2
  • 160=498V_2
  • V_2=0.32L=320mL
