There are 13 atoms in the product
<h3>Further explanation</h3>
Given
Reaction
H2SO4 + 2KOH --> K2SO4 + 2H2O
Required
The number of atoms 
Solution
In a chemical equation, there are reactants on the left and products on the right
Reactants : H2SO4 + 2KOH 
Products : K2SO4 + 2H2O
The number of atoms is determined by their reaction coefficient and the subscript of the atoms in the compound
K2SO4 (coefficient = 1) :
K = 2 atoms
S = 1 atom
O = 4 atoms
Total atoms = 7 atoms
2H2O(coefficient = 2) :
H = 2 x 2 = 4 atoms
O = 2 x 1 = 2 atoms
Total atoms = 6 atoms
Total = 13 atoms
 
        
             
        
        
        
Hexa- means six 
"hexa-" and it is in front of the fluoride so that means we have 6 fluorines
Answer:xenon hexafluoride →
