The empirical formula of the compound is C4H1.
An empirical formula represents the whole number ratio of various atoms present in a compound.
If the mass percent of various elements present in a compound is known, its empirical formula can be determined
We are given that a compound contains 4 mole C and 1 mole H.
Hence, the ratio of C: H is 4:1, which is already in the form of the simplest whole number.
Therefore, the empirical formula of the given compound is C4H1 and its molecular mass is 12 x 4 + 1 = 49.

The answer is: C) MgO + H2O.
Balanced chemical reaction: MgO + H₂O → Mg(OH)₂.
Synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
In this chemical reaction magnesium oxide and water react anf form magnesium hydroxide.
Other examples are not synthesis reactions.
