d. NO3
Explanation:
Answer:
its N³
Explanation:
In chemistry, a nitride is a compound of nitrogen where nitrogen has a formal oxidation state of −3.The nitride ion, N3−, is never encountered in protic solution because it is so basic that it would be protonated immediately. Its ionic radius is estimated to be 140 pm.

15. Ions formed in the product of Sodium nitride
Answer:
When it forms the nitride ion, it gains three electrons to form a 3- ion: N3− . In ionic compounds, the charges of constituent ions must balance. This can be achieved by having three sodium ions per nitride ion. Therefore, the formula of sodium nitride is Na3N
Explanation:
Sana makatulong16. The following is the chemical reaction for the synthesis of cesium and nitrogen forming cesium nitride, Cs3N: *see picture* 50 grams of cesium is combined with 50 grams of nitrogen to produce cesium nitride, Cs3N. What is the mass in grams of the excess reactant left after the reaction?
The balanced chemical equation for the synthesis of cesium nitride, Cs3N, from cesium and nitrogen is:
3Cs + N2 → Cs3N
The stoichiometric ratio of cesium to nitrogen in the reaction is 3:1, meaning that 3 moles of cesium reacts with 1 mole of nitrogen to form 1 mole of cesium nitride.
To determine the limiting reactant and the excess reactant, we need to calculate the number of moles of each reactant present:
Moles of Cs = 50 g / 132.9 g/mol = 0.376 moles
Moles of N2 = 50 g / 28.0 g/mol = 1.786 moles
According to the stoichiometry of the balanced equation, 1 mole of N2 reacts with 3 moles of Cs to produce 1 mole of Cs3N. Since we have more moles of N2 than required for the reaction, nitrogen is in excess and cesium is the limiting reactant.
The amount of cesium used up in the reaction is:
Moles of Cs used = 1/3 * Moles of N2 = 1/3 * 1.786 mol = 0.595 mol
The amount of cesium remaining after the reaction is:
Moles of Cs remaining = 0.376 mol - 0.595 mol = -0.219 mol
The negative value indicates that there is no cesium left over after the reaction and that all of it was consumed. Therefore, there is no excess reactant left in this case.
17. what is a percentage of sodium Na is in sodium nitride in Na3n
Answer:
83.12% is the percentage
Explanation:
Hope it helps
Answer:
8.313 Na
Explanation:
Na 3x23 =69
N 1x14=14
total: 83
Na 69g÷83=0.8313×100
=8.313%Na
ini-round off ko po yan↑↑
Na 3x22.9897693=68.9693079
N 1x14.007 =14.007
total: 82.9763079
Na 68.9693079/82.9763079=0.8311927783424550×100
=83.1192778342455%Na
