20 B203(s) + 12180 HF(l) = 4060 BF3(g) + 609 H20(l)
Answer:
≈ 1.142 moles
Explanation:
formula is “grams given/molar mass = moles”
nitrogen’s molar mass is 14.0067g
solve:
16 / 14.0067 = 1.14231046571
or ≈ 1.142 moles
hope this helped :)
Answer:
Radical chain initiator
Explanation:
The peroxide here serves as a radical chain initiator. In the field of chemistry the radical initiatives are those substances that are used in industrial processes like polymer synthesis. These initiatives have weak bonds generally and they're mostly used to create free radicals. These radicals are atoms that have odd numbers of electrons. Peroxide is an example of such.
Answer:
6 valence electrons
Explanation:
The atom you have given is a sulfur atom. It has 6 valence electrons.
Increase, because you need heat to melt a solid to a liquid, so the temperature will have to get greater.
