What is the molar mass of sodium bromide? A. 22.99 g

B. 1836.90 g

C. 58.44 g

D. 102.89 g

102.89g

Explanation:

The molar mass of sodium bromide is its gram per mole.

The formula of the compound is given as:

       NaBr ;

Atomic mass of Na = 22.9897g/mol

                           Br  = 79.904g/mol

So;

  Molar mass  = 22.9897 + 79.904  = 102.89g

the answers would be

the first one and the second one

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.
