10. Ethanol OH weighing 3.56 g is burned in a calorimeter. The temperature rises from 15.C to C. The temperature rises from 15.1 If to 28. heat of the bomb plus water is 8.224C. Find the Δ in kJ/mol.  (provide the given and required to find in the problem) (Kindly provide a CLEAR and COMPLETE solution) (Answer should be typewritten)

Please don't provide handwriting solution

A chemistry student dissolved 4.51 g of sodium hydroxide in 100.0 mL of water at 19.5 ºC (in a calorimeter cup). As the sodium hydroxide dissolves, the temperature of the surrounding water increases to 31.7 ºC. Determine the heat of solution of the sodium hydroxide in J/g. Specific heat of water = 4.184 J/g•ºC Select one: a.– 1182 J/g b.+1132 J/g c.+1180 J/g d.– 1132 J/g

The heat capacity of liquid water is 4.18 J/g.°C and the heat of vaporization is 40.7 kJ/mol. How many kilojoules of heat must be provided to convert 1.05 g of liquid water at 76°C into 1.05 g of steam at 100°C?

6) A block of rhenium metal (specific heat =0.0329 cal/ gC) is heated to 88.2C and then dropped into 100.0 g of water initially at 26.4 C. The final temperature of the mixture is 32.4C. What was the mass of the block of rhenium?

A solution is made by mixing 232.0 mL of ethanol initially at 12.7 ∘C with 232.0 mL of water initially at 22.5 ∘C. What is the final temperature of the solution assuming that no heat is lost? The density of ethanol is 0.789 g/mL and the density of water is 1.00 g/mL. The specific heat of ethanol is 2.46 J/g·°C and the specific heat of water is 4.184 J/g·°C ?f=        ∘C
