Calculate the heat of reaction for the following reaction: h2(g)+cl2(g)(g) round your answer to the nearest .

Given reaction:

H2(g) + Cl2(g) → 2HCl(g)

Formula:

Heat of the reaction is the enthalpy change given as:

ΔHrxn = ∑nΔH°f(products) - ∑nΔH°f(reactants)

          = [2ΔH°f(HCl(g))] - [ΔH°f(H2(g)) + ΔH°f(Cl2(g))]

          = [2(-92.31)] - [0 + 0] = -184.62 kJ/mol

The heat of the reaction is -184.62 kJ/mol

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
