Answer:
The answer to your question is the first choice (H₂)
Explanation:
Process
Look for the electronegativity of the elements of this exercise
a) H₂ = 2.2 - 2.2 = 0
b) NaF = 3.98 - 0.93 = 3.05
c) HBr = 2.96 - 2.2 = 0.76
d) HS⁻ = 2.58 - 2.2 = 0.38
The molecule that has the smallest difference in electronegativity is H₂
Answer:
the mass of 8.03 mole of NH3 is 136.51 g
Explanation:
The computation of the mass is shown below:
As we know that
Mass = number of moles × molar mass
= 8.03 mol × 17 g/mol
= 136.51 g
Hence, the mass of 8.03 mole of NH3 is 136.51 g
We simply multiplied the number of moles with the molar mass so that the mass could come
Answer:
There are 2 moles of oxygen molecules; there are 4 moles of oxygen atoms.
