For the equation that we are given:

[tex] CaO+H_{2}O [/tex] → [tex] Ca(OH)_{2} [/tex]

We see that on the reactants side we have:

Ca: 1 mol

O: 2 mol

H: 2 mol

And then we see that on the products side we have:

Ca: 1 mol

O: 2 mol

H: 2 mol

Therefore since we have equal moles of each of the elements on both sides of the equation, this equation is balanced how it is.

So the correct coefficients for this equation are: B) 1, 1, 1.

The coefficient correctly balance the equation: CaO + H₂O -> Ca(OH)₂ - 1;1;1.

To balance a chemical equation it is required that the moles of the atoms of reactants and the moles of atoms in the product are the same. To find the coefficient it is required to know the moles of each element in the given equation are present.

equation is - CaO + H₂O -> Ca(OH)₂

Reactants: CaO + H₂O

Ca - 1

O - 2

H - 2

Products: Ca(OH)₂

Ca - 1

O - 2

H - 2

Thus, both sides are already balanced in the given equation, so each reactant and product must have one coefficient each or 1, 1, 1.
