Answer:
Explanation:
Molarity is number of moles÷ volume of the solution.
Density = mass÷ volume.
Moles is mass÷molar mass
Molar mass of Nacl is 58.44g/mol
Moles is 1/58.44=0.017moles.
0.017 moles divided by volume which is 1.
Molarity is 0.017 moles
Molarity is the number of moles of solutes divided by volume of the solution.
Answer:
The answer to your question is ΔH = -964.2 kJ
Explanation:
Data
Reaction 1 X + 12O₂ ⇒ XO ΔH = -607.3 kJ
Reaction 2 XCO₃ ⇒ XO + CO₂ ΔH = 356.9 kJ
ΔH for Reaction 3 X + 12O₂ + CO₂ ⇒ XCO₃
Process
1.- Write the Reaction 1 the same
2.- Invert the order of reaction 2, and change the sign of the Enthalpy
Reaction 1 X + 12O₂ ⇒ XO ΔH = -607.3 kJ
Reaction 2 XO + CO₂ ⇒ XCO₃ ΔH = - 356.9 kJ
3.- Sum up the reactions
X + 12O₂ + XO + CO₂ ⇒ XO + XCO₃
4.- Simplify
X + 12O₂ + CO₂ ⇒ XCO₃ ΔH = -964.2 kJ
