Question

According to the following balanced reaction, how many moles of CaO are required to exactly react with 3.22 moles of H 2O?

CaO( s) + H 2O( l) → Ca(OH) 2( s)
a) 3.22 moles of CaO
b) 1.61 moles of CaO
c) 12.9 moles of CaO
d) 6.44 moles of CaO
e) 0.805 moles CaO

Answer 1

To determine the number of moles of CaO required to react with 3.22 moles of H2O, we first need to refer to the balanced reaction equation. From the balanced equation, we can see that 1 mole of CaO reacts with 1 mole of H2O to produce 1 mole of Ca(OH)2.

Step-by-step explanation:

To determine the number of moles of CaO required to react with 3.22 moles of H2O, we first need to refer to the balanced reaction equation. Unfortunately, the balanced reaction equation is not provided in the question. However, based on the information provided in the reference, let's assume the balanced reaction equation is as follows: CaO + H2O → Ca(OH)2.

From the balanced equation, we can see that 1 mole of CaO reacts with 1 mole of H2O to produce 1 mole of Ca(OH)2. Therefore, the number of moles of CaO required to react with 3.22 moles of H2O would also be 3.22 moles. This means the correct answer is not given among the options provided (6.44 moles of CaO and 0.805 moles of CaO).
