A 1.83 mol sample of carbon reacts with excess zinc oxide to produce zinc and carbon dioxide. How many moles of zinc oxide are consumed?

3.66 moles of Zinc Oxide are consumed

Explanation:

Based on the reaction:

C + 2ZnO → 2Zn + CO₂

Where 1 mole of Carbon reacts with 2 moles of Zin Oxide to produce 2 moles of Zinc and 1 mole of Carbon Dioxide.

To solve this question, we must convert the moles of carbon added to the moles of Zinc Oxide that react using the chemical equation (1mol C = 2mol ZnO):

1.83 moles C * (2mol ZnO / 1mol C) =

KE = 1/2mv^2 = (.5)(.00420kg) (965m/s)^2 = 1960J = 1.9 x 10^3J
