3. Identify the major products of the following reactions.
The thermite reaction is very exothermic, the heat of the reaction sufficient to melt the iron that is produced by the reaction:

2Al + Fe2O3 Al2O3 + 2Fe H=?

a) calculate the standard enthalpy change for this reaction?
b) if 40.0 g of iron (III) oxide we’re reacted with excess aluminum, how much heat would be produced ?
c) of the heat produced was used to heat 2.00L of water at 23.0C, what would the final temperature of the water be?
burning methan releases 890.4kj/mol-1 of methane burned in a hot water tank, natural gas is burned to release heat and warm up the water. what mass of methane would need to be burned to warm up 60.0 us gallons of water from 12.0c to 75.0 c?

A calorimeter is used to try To determine the enthalpy of combustion of a candle. The calorimeter contains 7.50 x 10^2 mL of water. The initial mass of the candle is 42.3g and the initial temperature of the water is 18.1 C. After being allowed to burn for a period of time, the candle is re-measured to have a mass of 38.8g and the temperature of the water is 55.6C.
a) how much heat energy was transferred into the water ?
b) how much energy was transferred per gram of paraffin wax?
c) How much energy was transferred per mile of paraffin wax?
d) If the theoretical enthalpy of combustion of paraffin wax is -42kj/g, what is the percentage difference ?
provide arrow pushing mechanism that accounts for the formation of the following product
I have a chemistry lab question and I need help
Determine the normality of thehe given hcl solutions by titrating against n /20 na2co3
A 1L sample of gas at 1atm pressure and 298K expands isothermally to 10L. It is then heated to 500K, compressed to 1L and then cooled 298K. What is the ∆E of the process?
The pH of a lake is 8.0. Over a 10 year period, the pH of the water becomes 1000x more
acidic.
