Answer:
ZcH's electrons = 5-2 = +3.
ZcH for inner electrons = -5 - 0 = +5.
Explanation:
Boron 1s² 2s² 2p
As, 2s ⇒ 2.58.
2p ⇒ 2.42.
Electrons = +3.
Greater than 2 cm = 0.35
Slightly greater than +3 .
Answer:
Gay-Lussac's law states that pressure and temperature are directly proportional
Explanation:
Gay-Lussac's law states that pressure and temperature are directly proportional. This always occurs if the volume keeps in constant.
n and V are not directly proportional, they are the same.
At Charles Gay Lussac's law
V1 = V2
n1 = n2
T1 < T2
P1 < P2
P1 / T1 = P2 / T2
If the pressure is contant:
V1 / T1 = V2 /T2
Answer:
15.52 kj
Explanation:
H2 O mole wt ~ 18 gm
6.35 gm is 6.35 gm /18 gm/mole = .353 moles of H2O
.353 moles * 44 kj/mole =
[Co(NH₃)₅Br]²⁺
Ligands and charges on them,
5 × NH₃ = 5 × 0 = 0
1 × Br⁻¹ = 1 × -1 = -1
Charge on sphere = +2
So, putting values in equation,
Co + (0)₅ - 1 = +2
Co + 0 - 1 = +2
Co - 1 = +2
Co = +2 + 1
Co = +3
Result:
Oxidation state of Co in [Co(NH₃)₅Br]²⁺ is +3.
