5. Use the known reactions to determine the AHxn of the following reaction.
C2H4(g) + Cl2 (8) - C2H4C12 (1)
4 HCl (g) + O2(g) → 2 Cl2(g) + 2 H2O (1)
AH° = -202.4 kJ/mol
2 HCI (g) + C2H4 + 1/2O2(0) CH. Cl20) + H2O (1) AH° = -318.7 kJ/mol

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

it is the most commonly accepted one

answer carbon and three oxygen atoms;

hypostyle hall;
