Reactant a contains 85.1 j of chemical energy. reactant b contains 87.9 j of chemical energy. product c contains 38.7 j of chemical energy. if the reaction absorbs 104.3 j of chemical energy as it proceeds, how much chemical energy must product d contain?

238.6 J

Explanation:

1) Chemical energy is indicated as enthalpy

2) Energy balance:

∑ enthalpy of the reactants + energy added = ∑ enthalpy of the products + energy released.

3) ∑ enthalpy of the reactants = 85.1 J + 87.9 J = 173 J

4) energy added = 104.3 J

5) ∑ enthalpy of the products = 38.7 J + D

6) energy released = 0

7) Equation:

173J + 104.3J = 38.7 + D + 0

⇒ D = 173J + 104.3J - 38.7J = 238.6J, which is the chemical energy of the product D.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
