4Al + 3O2 —> 2AL2O3
Answer is D
V = 3 x 1 x 1.5 = 4.5 cm^3
m = d x V
= 19.32 x 4.5
= 86.94g
<span>The answer is C)
mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9

Answer:
The intermolecular forces between water molecules are stronger than those between oxygen molecules. In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.
12.992 or 13 (rounded) hours
If you convert 1150km to miles it will be approximately 714.577 miles , now 714.577/55=12.992309090909090
