Answer:
Nitrogen has an atomic number of 7; the neutral Nitrogen atom has 7 protons and 7 electrons. If Nitrogen gained three electrons it would have 10 electrons, like the Noble gas Neon (10 protons, 10 electrons). However, unlike Neon, the resulting Nitrogen ion would have a net charge of N3- (7 protons, 10 electrons).
Explanation:
The rate of change of B is twice that of A, so:
rate of change of B = 2 x -0.1
rate of change of B = -0.2 M/s
Should remain the same, the volume will decrease.
Answer:
Q = 555200 J
Explanation:
∴ mass (m) = 80 kg
∴ c = 3470 J/Kg.K
∴ T1 = 37°C ≅ 310 K
∴ T2 = 39°C ≅ 312 K
⇒ ΔT = T2 - T1 = 312 K - 310 K = 2 K
⇒ Q = (80 Kg)*(3470 J/Kg.K)*(2 K)
⇒ Q = 555200 J ≅ 600000 J ≅ 6 E5 J
