The law of conservation of mass states energy can’t be created or destroyed, but can be interconverted. During those processes, you are not creating new molecules, but each molecule undergoes a mechanism to be converted to another.
Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
Explanation:
Answer:
Cold climates favor mechanical weathering.
Explanation:
I just took the test and this is the correct answer!
Answer:
1.25 mol LiF
Explanation:
5.00 M solution means
5.00 mol LiF in 1 L solution=1000mL
x mol LiF in 250 mL
x = 5.00*250/1000 = 1.25 mol LiF
