Answer:
-heat and pressure is your answer
<em>Balance Chemical Equation:</em>
2H3N(aq) + 3Ca(OH)2(aq) → Ca3N2(aq) + 6H2O(liq)
<em>Explanations:</em>
- According to law of mass of conservation, the chemical equation should be balanced.
- In balance chemical equations, the numbers of same or different atoms in reactants should be equal to the number of different atoms of elements of product side.
Answer:
Explanation:
1. a student conduct an experiment she found that her actual yield was
20g. the theoretical yield for the experiment is 25g. calculate the percent
yield for the reaction
Hello there.

Elements with three p-electrons....
That would be N, P, As, Sb, and Bi -- elements in group 15
For example, energy diagram showing "empty" orbitals up through the 3p.

Energy diagram of phosphorous showing three unpaired electrons in 3p-sublevel
.....3p ↑_ ↑_ ↑_
3s ↑↓
.....2p ↑↓ ↑↓ ↑↓
2s ↑↓
1s ↑↓
According to Hund's rule, the electrons singly occupy the p-orbitals, and all have the same spin.
