Scandium forms one ion, Sc3+, with an electron configuration of 1s2 2s2 2p6 3s2 3p6
<span>So, when you make something boiling or melting, its still the same substance. Water doesn't change into something else, just change its state of matter. When you burn something, one substance reacts with another. For example, when you burn carbon in oxygen, you get carbon dioxide. That's the difference.</span>
Answer : The mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.
Explanation :
As we are given that, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide. Now we have to determine the mass of nitrous oxide formed from 85.20 g of nitrogen.
As, 28.01 g of nitrogen is present in 44.01 g of nitrous oxide
So, 85.20 g of nitrogen is present in
of nitrous oxide
Thus, the mass of nitrous oxide formed from 85.20 g of nitrogen is, 133.9 grams.

Answer: 2800 g
Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number
of particles.
Given mass = 5 kg = 5000 g
1 mole of
produces = 1 mole of 
50 moles of
produces =
of 
Mass of 
2800 g of
is produced from 5.0 kg of limestone.
