Question

C⁶H¹²O⁶»2C²H⁵OH+2CO²+Energy
1. How many atoms of each element are present in one molecule of the reactant?​

Answer 1

$\huge\pink{Hey Mate}$

Lets begin by counting the atoms of each element in each compound ...

In C6H12O6

Number of atoms of carbon = 06

Number of atoms of hydrogen = 12

Number of atoms of oxygen = 06

In 2C2H5OH

Number of atoms of carbon = 04

Number of atoms of hydrogen = 12

Number of atoms of oxygen = 02

In 2CO2

Number of atoms of carbon = 02

Number of atoms of oxygen = 04

So now the total number of atoms are as follows :

Carbon : 6+4+2 = 2

Hydrogen : 12 + 12 = 24

Oxygen: 6+2+4 = 12
