Pretty much, for solids draw the molecules close together and rigid, for liquids, the molecules are spaced apart a little and not all lined up
Answer:
False
Explanation:
Chemical reaction equation:
C₅H₁₂ + 8O₂ → 2CO₂ + 6H₂O
Most chemical reactions obey the law of conservation of mass. By so doing, the number of chemical elements on both sides of the expression must be balanced.
Reactants Products
C 5 4
H 12 12
O 16 10
We see that for C and O, the number of atoms on both sides of the expression differs and so, it is not balanced.
