Answer:
Yes
Explanation:
AsH3 contains a polar bond.
Answer:
C
Explanation:
This is the only option that could produce an objective answer through experimentation or studies. The other options can be answered subjectively and are opinion based. They could not be answered scientifically.
We can exemplify with H2O (water)
H= nonmetalic
O= Nonmetalic
A bond with nonmetalic and nonmetalic is covalent bond.
Hope it helps!!

Answer:
The sample obtained from the environment has a higher mass
Explanation:
A simple way to put the answer is that the element carbon -as found in nature- has a molar mass of 12.0107 g/mol, because there are a few isotopes of 14C and 13C; and <em>the molar mass is an expression of the isotopes' natural abundance</em>.
So 1 mole of carbon obtained from the environment would weigh 12.0107 g, while a sample of isotopically pure carbon would weigh 12.0000 g.
