They evaporate . The answer is D
Nuclear power plants generate heat by a nuclear reaction and lets out less pollution, a power plant generates electricity by burning fossil fuels and lets out more pollution
The equation is as below,
<span>5 Ag</span>⁺ (aq) + Mn²⁺ <span>(aq) + 4H</span>₂<span>O (l) → 5Ag (s) + MnO4</span>⁻<span>(aq) + 8H</span>⁺ <span>(aq)
Reduction:
According to eq. Silver is reduced as,
</span>
5 Ag⁺ + 5 e⁻ → 5 Ag
One electron is gained per Ag ion, so 5 Ag ions will gain 5 electrons.
Oxidation:
According to eq. Manganese is Oxidized as,
Mn²⁺ → MnO4⁻
Oxidation number of Mn in MnO₄⁻ is +7, so Mn²⁺ is loosing 5 electrons, Hence,
Mn²⁺ → MnO4⁻ + 5 e⁻
Results:
Hence, 5 moles of electrons are exchanged between oxidizing and reducing agents.
The element which can not loose electron easily and having electronagtive character is called non-metal it has following property-
1. it can not conduct heat and electricity
2. it is netiher ductile not malleable
3. it is not lsuturous and also not sonorous
Given,
1 gram remain out of 16 grams after 237 seconds.
So,
1g -> 2g -> 4g -> 8g -> 16g
So, 4 half lives have taken palce.
So,
we divide 237 by 4 and we get our answer.
So,
234 / 4 = 59.25 ≈ 59.3
So, the answer is (2) 59.3 seconds
