Answer:
5- number of electrons=11
Explanation:
in a neutral atom number of protons=number of electrons which in this case=11
2 C5H12O + 15 O2 = 10 CO2 + 12 H2O
Hope this helped :)
According to the kinetic theory of gases, the collisions among the molecules are perfectly elastic, that is, when the collision of the molecules takes place, they bounce off each other with no gain or loss of energy. No repulsive or attractive forces take part at the time of collisions, so energy is conserved.

Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A double replacement reaction is one in which exchange of ions take place.
