A Skeleton equation is a chemical equation that does not indicate relative amounts of reactants and products. Answer: D)
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. ... is the heat added to, or removed from, the system.
Answer:
3.00 mol NH₄Cl
Explanation:
Step 1: Write the thermochemical equation for the production of ammonuim chloride
NH₃(g) + HCl(g) → NH₄Cl(s) ΔH = –176 kJ
Step 2: Calculate the number of moles of NH₄Cl produced if the change in enthalpy is –528 kJ
According to the balanced thermochemical equation, 176 kJ are released when 1 mole of NH₄Cl is produced. The moles of NH₄Cl produced if the change in enthalpy is –528 kJ is:
-528 kJ × 1 mol NH₄Cl/(–176 kJ) = 3.00 mol NH₄Cl
