What is the percent composition of beryllium (Be) and oxide (O) in BeO? Round your answer to the nearest whole percentage.

Explanation:

Hello!

In this case, since the percent compositions of Be and O in beryllium oxide are computed as shown below:

Since atomic masses are respectively 9.01 and 16.0 g/mol and the molar mass of the compound is 25.01 g/mol, the resulting percent compositions are:

Best regards!

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
