Find a snack food. Determine the grams of fat, protein, and carbohydrate in one serving. Determine the number of "food calories" (Cal) per gram of fat, protein, and carbohydrate. Which of these biomolecules has the highest number of Cal/gram?
Now based on this information, which is the best energy storage form for the body?
1Cal = 1000 cal 1 cal = 4.184 J. How many Joules are there in one serving of your snack?
Water has a specific heat of 4.184 J/g ºC. How many grams of water can be warmed 1 ºC by a serving of your food?© BrainMass Inc. brainmass.com October 24, 2018, 10:46 pm ad1c9bdddf

8.Calculate the mass of potassium chlorate needed to prepare 5.00L of oxygen gas at 24.0oC and 0.950 atm. (When using atmospheres, the gas constant, R=0.0821L ∙ atm ∙ mol-7 ∙ K-1).
The equation is KClO3 → KCl + 3O2.
9.Consider the following reaction, which takes place in an autoclave at 250oC and 800 atm.
NH3(g) + 7O2(g) → NO2(g) + 3H2O(g)
Into the reaction vessel has been placed 200L of NH3(g) and 120L of O2(g). The reaction is allowed to go to completion. Determine the quantity, in moles, of the gas that remains unreacted.View Full Posting Details
