HCIO, How many atoms are in the chemical formula shown?

A) 2
B) 3
C) 4
D) 5

Explanation:

First, identify the elements.

Next, identify any subscripts or coefficients. This would indicate there are multiple atoms of each element or group of elements.

There are none, so each element has 1 atom.

There are 3 elements with 1 atom each, so 3*1= 3

This chemical formula has 3 atoms and B is correct.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the answer would be c
