Answer:
b) heating, cooling
Explanation:
Heating will favour dissolution (it helps dissolving faster).
Cooling helps in crystallization.
Answer:
D. N₂O
Explanation:
Let's assume we have 100 g of the compound. That means it consists of 63.61 grams of nitrogen and 36.69 grams of oxygen.
Converting masses to moles:
63.61 g N × (1 mol N / 14.01 g N) = 4.540 mol N
36.69 g O × (1 mol O / 16.00 g O) = 2.293 mol O
Normalize by dividing by the smallest:
4.540 / 2.293 = 1.980 mol N
2.293 / 2.293 = 1.000 mol O
So there is approximately twice as many N atoms as O atoms. The empirical formula is therefore N₂O.
The neutrino is the particle that cannot be accelerated in a
magnetic field.
To add, a neutrino is a subatomic particle that is
very similar to an electron, but has no electrical charge and a very small
mass, which might even be zero.
Answer:
I think that the answer is N20:2(14.01)+1(16.06)=44.02g/mol(c) fluorine Di nitrogen monoxide contains how many mom 6.022 x
1023 mol N20
