Determine the number of each type of atom in each of the following formulas.

(a) Ba(OH)2(subscript) Ba
1. O
2. H
3. Ba

thanks

i got it

2O

2H
1Ba

To determine the number of each type of atom in the formula Ba(OH)2, you should break down the formula into its individual elements.

In this case, the formula consists of the following elements:
- Ba (barium)
- O (oxygen)
- H (hydrogen)

To determine the number of each type of atom, you need to consider the subscripts present in the formula. The subscript indicates the number of atoms for each element.

In the formula Ba(OH)2, the subscript "2" applies to both the H and the O. This means that there are two atoms of hydrogen (H) and two atoms of oxygen (O).

The subscript outside the parentheses, "1," applies to the Ba. Therefore, there is one atom of barium (Ba).

So, the number of each type of atom is as follows:
1. Ba: 1 atom
2. O: 2 atoms
3. H: 2 atoms
