Question

Determine how many of each type of element are represented in the chemical formulas CaBr_2.

Answer 1

In the chemical formula CaBr2, there is 1 atom of calcium (Ca) and 2 atoms of bromine (Br), forming calcium bromide.

Step-by-step explanation:

To determine how many of each type of element are represented in the chemical formula CaBr2, we need to examine the subscripts of each element within the compound. In the case of calcium bromide (CaBr2), the chemical formula indicates there is 1 atom of calcium (Ca) and 2 atoms of bromine (Br) in each molecule of the compound.

We can break down the process in the following steps:

1. Count the number of each type of atom in the formula.
2. Multiply the number of atoms by the atomic mass for each element (Ca = 40.078 g/mol, Br = 79.904 g/mol).
3. Add up the masses for all of the elements.

Therefore, in one molecule of CaBr2, there is 1 atom of calcium and 2 atoms of bromine.
