The reaction of carbon dioxide(g) with hydrogen(g) to form carbon monoxide(g) and water(g) proceeds as follows: co2(g) + h2(g) > co(g) + h2o(g)when 16.4 grams of co2(g) react with sufficient h2(g) , 15.4 kj of energy areabsorbed .what is the value of > h for the chemical equation given? δhrxn = kj

ΔHrxn = 41.3 kJ

Explanation:

Let's consider the following equation.

CO₂(g) + H₂(g) ⇒ CO(g) + H₂O(g)

When 16.4 g of CO₂ react 15.4 kJ of energy are absorbed. In the balanced equation, there is 1 mole of CO₂, so we have to calculate the heat absorbed per mole of CO₂. Taking into account that the molar mass of CO₂ is 44.01 g/mol, the enthalpy of reaction (ΔHrxn) is:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
