Answer:
5.8125*10^-3
the moles in Fe2O3 are 0.93/(56*2 + 16*3) = 5.8125*10^-3

Q = mCΔT
Q is heat, m is mass, C is specific heat, and ΔT is change in temp
First, find how much energy you need to raise the heat to 100C, or the boiling point
Q = (50g)(4.18)(75 degrees) = 15675 J or 15.675 kJ
Then you need 40.7 kJ extra for each mole of water to evaporate it
If you have 50 grams of water and there are 18 grams per mol
50g / 18g = 2.8 moles x 40.7 = 113 kJ extra
15.675 + 113 kJ = 128.7 kJ required
Answer:
METHANE IS COMPARITIVELY LESS TOXIC AND INFLAMMABLE S COMPARED TO OTHER LABORATORY USED GASES.
Explanation:
THEREFORE,IT CAN BE USED IN THE LABS DUE TO IT'S LESS TOXICITY AND USAGE IN EXPERIMENTS.
