Consider the chemical reaction aC2H6 + bCO2 + cH2O → dC2H5OH,
where a, b, c, and d are unknown positive integers. The reaction mush be balanced; that is, the number of atoms of each element must be the same before and after the reaction. For example, because the number of oxygen atoms must remain the same,
2b+c=d.
While there are many possible choices for a, b, c, and d that balance the reaction, it is customary to use the smallest possible integers. Balance this reaction.
a=
b=
c=
d=

Explanation:

aC2H6 + bCO2 + cH2O → dC2H5OH

The balanced equation for the reaction is given as;

6C2H6 + 2CO2 + 3H2O → 7C2H5OH

Check!

Oxygen

Reactant = 2 * 2  +  3  =  7

Product = 7

Carbon

Reactant = 6 * 2  +  2  = 14

Product = 7 * 2 =14

Hydrogen

Reactant = 6 * 6  + 3 * 2  = 42

Product = 7 * 5 + 7 * 1 = 42

a = 6

b = 2  

c =  3

d = 7

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
