Explanation:
Nitrogen triiodide (NI₃)
Valence electrons of nitrogen = 5
Valence electrons of iodine = 7
The total number of the valence electrons = 5 + 3(7) = 26
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is shown in image below.
Nitrogen posses one lone pair and thus the geometry is pyramidal.
Answer:
A.
Explanation:
the gradual movement of the continents across the earth's surface through geological time.
Answer:
Q = 4.056 J
Explanation:
∴ m = 406.0 mg = 0.406 g
∴ <em>C </em>= 1.85 J/g.K
∴ T1 = 33.5°C ≅ 306.5 K
∴ T2 = 38.9°C = 311.9 K
⇒ ΔT = 311.9 - 306.5 = 5.4 K
⇒ Q = (0.406 g)(1.85 J/gK)(5.4 K)
⇒ Q = 4.056 J
Answer:
the answer is 4.0moles
Explanation:
1mole of O2 produce 2moles of H2O/x mole will produce 8.0moles of H2O then the answer is 4.0moles.
Explanation:
Solar energy is the radiant energy emmitted from the Sun. It is the electromagnetic energy
