The answer to your question is : no.of moles of Si = 43/atomic mass of Si = 43/28.1 = 1.53
according to reaction 3 moles of Si gives 1 mole of Si3N4
so 1.53 mole of Si will give 1.53/3 = 0.51 mole of Si3N4
molar mass of Si3N4 = 140.28 g/mole
it means that 1 mole of Si3N4 = 140.28 g
so 0.51 mole of Si3N4 = 0.51 X 140.28 = 71.543 g
Answer:
pauli exclusion principle states that no two electrons in the same orbital can have the same spin.
Explanation:
this means you can't have 2 up arrows or 2 down arrows in your box
Looks like 3*.5 mol of N, or 1.5*.5 N2
<span>convert that to grams.</span>
C because it’s reshaping it, it stays the same but just reshaping it
