I disagree. Carbon is not a group 18 element. This is incorrect because elements closer to the top of the group are less reactive than those at the bottom of the group. Group 18 elements are noble gases and carbon, a group 14 element, is a non metal.
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.
It’s gotta be e he was like i and we are all over here we have never it again
Al +3CuCl--->AlCl3+3Cu , its balanced equation
