write the role of nitrogen and calcium.
Answers
Answer:
Calcium is a metal, so its formula will simply be
Ca
.
Nitrogen is a diatomic molecular compound, making it
N
2
.
Since calcium nitride is an ionic compound, by evaluating its constituent ions we can determine its formula. The calcium ion is a 2+ ion, or
Ca
2
+
. The nitride ion is a 3- ion, or
N
3
−
. As such, to balance the charges we require 3x calcium ions for every 2x nitride ions, or
Ca
3
N
2
.
∴
C
a
(
s
)
+
N
2
(
g
)
→
C
a
3
N
2
(
s
)
Balancing the equation, then, you will notice that the number of nitrogens on each side balances However, on the left side of the equation we have
1
calcium, and on the right we have
3
. We can balance this simply by increasing the number of calciums on the left to
3
, as demonstrated in the answer above.
Answer:
Nitrogen:-
It is a naturally occurring element that is essential for growth and reproduction in both plants and animals.
Calcium:-
It is one of the most important minerals for the human body. It helps form and maintain healthy teeth and bones.
