Answer:
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with a definite volume.
Explanation:
I honestly don't know if that's right...
Answer:
3.78 gm O2
Explanation:
In the reaction represented by the equation 2Al2O3 → 4A1 + 302, calculate the theoretical amount in grams of oxygen, O2 produced if 11.84 grams Al2O3 decomposes?
for every 2 moles of Al2O3, 3 mole of 02 are produced
molecular weight of Al2O3 =(2X27) + (3X32) =54+96= 150
11.84 gm Al2O3 = 11.84/150 moles =0.0789 moles
This will produce 3/2 X 0.0789 moles of O2 = 0.118 moles O2
mol wt of O2 is 32
0.118 moles weighs 0.118X32 = 3.78 gm O2
I think it would be A. base pairs but that is my best answer Have a great day!
Answer:
we count the number of the molecules on each side of the equation.
Fusion creates less radioactive material and has nearly an unlimited fuel supply. Fusion also makes several times more energy than fission.
