Propane burns in oxygen to produce carbon dioxide and water. What are the chemical
formulas of the reactants and products?
The formulas of the reactants are C3H8, O,
and CO2. The formula of the product is H20.
The formulas of the reactants are C3Hg and
O2. The formulas of the products are CO and
H20.
The formulas of the reactants are C3Hg and
02. The formulas of the products are CO2
and H20.

Reactants are C3H8 and O2

Products is CO2 and H20

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
