When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form CO2 (carbon dioxide), which is
Monica [59]

Answer:

1.239 * 10^8 Kg

Explanation:

Since all the electricity consumed comes from natural gas;

amount of electricity consumed = 700 * 300,000 = 2.1 * 10^8 kWh

So, amount of CO2 consumed is given by;

amount of electricity consumed * amount of CO2 per kWh

Hence,

Amount of CO2 = 2.1 * 10^8 kWh * 0.59 = 1.239 * 10^8 Kg

Calculate the enthalpy change for the reaction 2 hcl → h2 + cl2 1. +184 kj/mol of rxn 2. +428 kj/mol of rxn 3. 0 kj/mol of rxn 4
lesantik [10]
Below is the list of enthalpies of formation of the compounds involved in the chemical reaction.

HCl: -92.3 kJ/mol
H2: 0 
Cl2: 0

Both H2 and Cl2 do not have enthaply of formation because they are pure substances. 

Since, in the reaction there are 2 moles of HCl,
   Enthalphy of formation = enthalpy of products - enthalphy of reactant/s
                = 0 - (-92.3)(2) = +184.6 kJ

Hence, the answer is the first choice.
