I don't know man hahahaha
<h3>
Answer:</h3>
12 moles
<h3>
Explanation:</h3>
The equation for the reaction;
CuO(s) + H₂(g) → Cu(s) + H₂O(g)
We are given;
- Moles of copper, Cu is 12 moles
We are required to calculate the number of moles of CuO required;
- From the reaction 1 mole of CuO reacts to produce 1 mole of copper
- Thus, the mole ratio of CuO to Cu is 1 : 1
- Moles of CuO = Moles of Cu
Thus, moles of CuO = 12 moles
Therefore; 12 moles of CuO will be required.
<h2>
Answer:C</h2>
Explanation:
A chemical equation is a equation that describes a corresponding chemical reaction.
A chemical reaction is generally written as
→
refer to all the reactants involved in the chemical reaction.
Reactants are usually written on the left hand side of the chemical equation.
refer to all the products formed in the chemical reaction.
products are usually written on the right hand side of the chemical equation.
In the given reaction,
,
are written on the right side of the equation.
So,
,
are the products.
