Hydrogen reacts with chlorine to form hydrogen chloride (hcl (g), mc012-1.jpghf = –92.3 kj/mol) according to the reaction below.
which statement is correct?
the enthalpy of the reaction is –184.6 kj, and the reaction is exothermic.
the enthalpy of the reaction is –184.6 kj, and the reaction is endothermic.
the enthalpy of the reaction is 184.6 kj, and the reaction is endothermic.
the enthalpy of the reaction is 184.6 kj, and the reaction is exothermic.

Given:

H2(g) + Cl2 (g) → 2HCl (g)

To determine:

The enthalpy of the reaction and whether it is endo or exothermic

Explanation:

Enthalpy of a reaction is given by the difference between the enthalpy of formation of reactants and products

ΔH = ∑nHf (products) - ∑nHf (reactants)

      = [2Hf(HCl)] - [Hf(H2) + Hf(Cl2)] = 2 (-92.3) kJ = - 184.6 kJ

Since the reaction enthalpy is negative, the reaction is exothermic

Ans: The enthalpy of reaction is -184. kJ and the reaction is exothermic

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'
