The answer to this question will depend on what the substance that is reacting is. You will need to find the appropriate standard enthalpy value, which corresponds to the amount of enthalpy change when one mole of matter is transformed by a chemical reaction in standard conditions.

When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
How much heat is involved in the synthesis of 5.0 moles of ammonia?
46.2 kJ/mole of heat is a part of the synthesis of 1.0 mole of ammonia. As a result, 231 kJ/mole of heat will result in the synthesis of 5.0 moles of ammonia.
How much heat is absorbed when 75 g of liquid carbon tetrachloride (CCl4) vaporizes into a gas?
Approx. 15 kJ.
How much tin metal will react with 32.0mL of a 1.75M solution of hydrochloric acid to produce hydrogen gas?
I assume by " much " you mean grams tin. Balanced equation first.Sn + 4HCl -> SnCl4 + 2H2Now, find moles HCl by......Molarity = moles of solute/Liters of solution ( 32.0 ml = 0.032 Liters )1.75 M HCl = X moles/0.032 liters= 0.056 moles HCl=============== Now,0.056 moles HCl (1 mole Sn/4 moles HCl)(118.7 grams /1 mole Sn)= 1.7 grams of tin-----------------------
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
How much energy is absorbed when 23.1 moles of water vaporize?
540 calories per gram is absorbed when water vaporizes at its boiling point. Called the latent heat of vaporization. 540 x 23.1 x 18 = 224532 calories
What factor determines how much heat can be absorbed by the brakes drum?
Too much heat would result in brake damage, which is absorbed in the brake drum.
How much heat is absorbed by land and sea?
51%
How much energy in kilocalories is absorbed when 9.0 mol of water is vaporized?
Molecular weight of water is 18 so 9 moles is 162 grams. Latent heat of vaporisation is 550 cal/gram, so the amount of heat is 89100 cal or 89.1 kcal.
When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
How does cotton react to heat?
No, it stays pretty much the same.
How much heat is involved in the synthesis of 5.0 moles of ammonia?
46.2 kJ/mole of heat is a part of the synthesis of 1.0 mole of ammonia. As a result, 231 kJ/mole of heat will result in the synthesis of 5.0 moles of ammonia.
How much heat exactly is absorbed by the ozone or what temperature would the earth be if there was no ozone?
23 percent of incoming solar energy is usually absorbed by the ozone. Temperature, not how much
How much X will remain in 4.0 moles of X and 3.8 moles of Y are allowed to react. X plus 5Y equals 3Z?
for every 5 moles of y there is 1 mole of x, so 3.8/5 is .76
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How much heat is needed to make 2.00 moles of Cl2 gas?
The necessary heat to transform liquid chlorine (Cl2) to a gas is 9,756 kcal.
When 10g of diethyl ether is covered to vapor at its boiling point about how much heat is absorbed?
2 kJ.
