How many moles of H2O can be formed when 4.5 moles of NH3 react with 3.2 moles of O2?

1 answer:

3 0

Hi Sentpain! Thanks for asking a question here on Brainly.

Solving:

4 NH3 +5 O2 = 4 NO + 6 H2O

☛ Find the ratio for NH3 and O2. That's 4:3
☛ 4.5 x 5 /4 = 5.6
☛ Find the ratio for O2 and H2O. That's 5:6
☛ 3.2 x 6 / 5 = 3.8

Answer: 3.8 mol H2O - choice A

Hope that helps! ★ If you have further questions about this question or need more help, feel free to comment below or leave me a PM. -UnicornFudge aka Nadia

Consider the following reaction: 2CH3OH ---> 2CH4+O2 delta H= +252.8kJ. Calculate the amount of heat transferred when 22.0g o

nydimaria [60]

To calculate the amount of heat transferred when an amount of reactant is decomposed, we must look at the balanced reaction and its corresponding heat of reaction. In this case, we can see that 252.8 kJ of heat is transferred per 2 moles of CH3OH used. When 22 g of CH3OH is used, 86.9 kJ is absorbed.
