How many grams of c₆h₆ must decompose according to the following chemical equation to transfer 430kj of heat?
c₆h₆(l) → 3 c₂h₂(g)∆h= 630 kj

THE NUMBER OF GRAMS OF PRODUCED IS

Explanation:

The given equation is ,

ΔH=;

the number of moles '' that will decompose is :

Thus,

The number of grams = no.of moles weight of one mole

weight of one mole = 6(mass of one mole of ) + 6(mass of one mole of )

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
