What is the standard enthalphy change δho, for the reaction represented above? (δhof of c2h2(g) is 230 kj mol-1; (δhof of c6h6(g) is 83 kj mol-1; )

-608KJ/mol

Explanation:

3 C2H2(g) -> C6H6(g)

ΔHrxn = ΔHproduct - ΔHreactant

ΔHrxn= ΔHC6H6 - 3ΔHC2H2

ΔHrxn = 83 - 3(230)

ΔHrxn = -608

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

answer; i do believe the correct answer is (river); /// good luck
