it will be 11,700J
since the formula would be:
q=mHf=35g x 334 J/g= 11,700 J

How much heat energy must be absorbed to completely melt 35.0 grams of water at 0 degrees Celsius?
Ice at 0 deg C has a latent heat of melting of 335 kJ/kg. If you have 35 grams (0.035 kg), then it would take exactly 11.725 kJ to melt the ice to get 35 grams of water at 0 deg C.
If 108 grams of Al are allowed to completely react with 318 grams of FeO how many grams of AlO and Fe will be produced?
42 , and 28.
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of ovygen?
43.2 grams of water
What would be the final temperature when 250 grams of water at 100 degrees celsius is mixed with 525 grams of water at 30 degrees celsius?
The temperature would be that of water's boilng point od 100 degrees
How many grams of carbon dioxide would be produced if 45 grams of glucose completely react with oxygen?
66g
How much heat energy is absorbed in 65 gram sample whose temperature changed from 45 to 80 degrees celsius?
That completely depends on the specific heat capacity of the substance of which the sample is composed, which you haven't identified. It will take a lot more heat energy to raise the temperature of 65 grams of water 35 degrees than it would take to do the same to 65 grams of iron or yogurt, e.g.

How much energy is absorbed by 50 grams of water if the temperature changes from 22 degrees celsius to 28 degrees celsius?
Change in temp = 28° - 22° = 6°. Heat capacity of liquid water is 1 calorie per gram per degree(C).So the energy absorbed is (50) x (6) = 300 calories.
How many kilojoules of heat are absorbed when 70.00 grams of water is completely vaporized at its boiling point?
158.1Kj
How is stoichiometry used to calculate energy absorbed when mass of solid melts?

What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?
(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.
How many joules are absorbed by the water with a mass of 8 kg in order to raise the temperature from 20 degrees to 70 degrees?
q(joules) = mass * specific heat * change in temperature ( 8 kg = 8000 grams ) q = (8000 grams H2O)(4.180 J/gC)(70o C - 20o C) = 1.7 X 106 joules ============
How many joules of heat energy must be supplied to 21 g of water to raise the temperature of the water from 24 to 95 degrees Celsius?
21 grams through 71 degrees is 21x71 calories.
How many grams of water were involved if a mass of water dropped in temperature by 25.1 degrees celcius. It gave off 5240.0J of energy in the process.?
k
How many grams of antimatter are needed to react with 5 g of matter?
Exactly 5 grams of antimatter will completely annihilate 5 grams of matter, producing an enormous shower of high energy gamma rays. In total a mass of 10 grams will be converted to the equivalent amount of energy.
