The overall atom is non-polar because there are two negatively charged sides instead of one positive side and one negative side.
Answer: D
Explanation:
Because at temerature at 25 and 50 is
to low for a compound to evaporate as gas because the bioling point is 100.
Answer is: <span>b.20.0 L </span><span>liters of ammonia are needed to react completely.
</span>V(NO) = 30 L.
n(NO) = V(NO) ÷ Vm.
n(NO) = 30 L ÷ 22,4 L/mol.
n(NO) = 1,34 mol.
From chemical reaction: n(NO) : n(NH₃) = 6 : 4 (3 : 2).
n(NH₃) = 4 · 1,34 mol ÷ 6.
n(NH₃) = 0,892 mol.
V(NH₃) = 0,892 mol · 22,4 L/mol.
V(NH₃) = 20 L.
The metric system is used all around the world because it goes off a ten number base and is easy to calculate.
qualitative data is in words
quantitative data is in numbers
