Answer:
its is because the chemicals are very diffraction from each other so which makes it difficult to form a chemical bond.
Explanation:
Number of oxygen molecules = 10 billion = 
Number of hydrogen molecules = 10 billion =
Number of molecules of hydrogen peroxides = 10 billion =
Moles of oxygen gas :
Moles of hydrogen gas :
Moles of hydrogen gas :
Number of moles in hydrogen gas, oxygen gas and hydrogen peroxide is same.
Total number of atoms in 
molecules of oxygen:
(2 atoms in 1 molecule)
Total number of atoms in molecules of hydroegn :
(2 atoms in 1 molecule)
Total number of atoms in molecules of hydrogen peroxide:
(4 atoms in 1 molecule)
Number of oxygen atoms and number of hydrogen atoms are equal but individually they are not equal to number of atoms in hydrogen peroxide.
Convection
Explanation:
Convection is form of heat transfer by which heat moves through liquid and circulates due to density differences.
There are three major forms of heat transfer:
- Conduction is form of heat transfer that involves contact between two bodies in which collision between their molecules caused heat exchange from the hot body to the cold one.
- Radiation is a form of heat transfer that does not involve contact. It involves the use of electromagnetic waves of different forms.
- Convection occurs in fluids in which heat transfers as a result of movement of molecules of the medium from one point to the other. The hotter body becomes lighter and rises whereas the colder ones sinks.
