Chemistry Help, Please?
1.Calculate the amount of heat energy needed to raise the temperature of the water in 40.-gal (151-kg) home water heater from 19.0 Celcius (66.2 F) to 60.0 Celcius (140. F).
2. What quantity of heat energy is needed to raise the temperature of 1 pound (454g) of aluminum from 25.0 Celcius to its melting point, 660. Celcius? (csp(al)=0.900 J/g.Celcius)
3.Sodium metal reacts violently with water to produce aqueous sodium hydrogen gas. Calculate the enthalpy change for this reaction.
4. Propane (C3H8), the major component of LP gas, is often used as a heating and cooking fuel in homes, RV’s, and camping equipment, and can alsoe be used as a motor fuel. when propane is burned (reacted with oxygen), C02 (g) and H2O (g) are produced.
A. Write and equation for the reaction and calculate the enthalpy change for the combustion of propane.
B.How much heat can be produced by the combustion of 50.0 g propane?
Any help is appreciated…
Don’t they have the answers in the back of the book?
