Explanation:
All matter has mass and occupies space. Volume is a measure of how much space an object occupies. ... "Mass" only depends on how much matter is in an object. "Weight", on the other hand, depends on how strongly gravity pulls on an object.
Answer:
2390 CuO
Explanation:
2 NH3(g) + 3 CuO(s) ---> 3 Cu(s) + N2(g) + 3 H2O(g)
from reaction 3 mol 1 mol
given x mol 10.0 mol
x = 3*10.0/1 = 30.0 mol
M(CuO) = 63.5 + 16.0 = 79.5 g/mol
m(CuO) = 30.0 mol CuO * 79.5 gCuO/1 mol CuO = 2390 g CuO
I'm not sure but I think it is similar atomic numbers
All of these are compounds except oxygen because a compound is two or more different elements bonded together.
Boiling point is the only answer that doesn’t have to do with their physical property
