Atomic fission requires temperatures of one million degrees or hotter.<br><br> True <br> False

pickupchik [31]

<u>Answer:</u> The correct answer is false.

<u>Explanation:</u>

Atomic fission reactions are defined as reactions in which nucleus of an atom splits into two or more smaller nuclei. These reactions are carried out in nuclear reactors. The temperature range for the reactors are around 300°C.

Atomic fusion reactions are the reactions in which nucleus of two or more atoms fuse together to form one large nuclei. These reactions require a huge amount of energy to occur. The temperature required by these reactions are about one million kelvins.

Hence, the given statement is False.

If air contains 78% Nitrogen by volume, what is the solubility of nitrogen in water at 25 degree celisus

Svet_ta [14]

The solubility of nitrogen in water at 25 °C= 4.88 x 10⁻⁴ mol/L

<h3>Further explanation</h3>

Given

78% Nitrogen by volume

Required

The solubility of nitrogen in water

Solution

Henry's Law states that the solubility of a gas is proportional to its partial pressure

Can be formulated

S = kH. P.

S = gas solubility, mol / L

kH = Henry constant, mol / L.atm

P = partial gas pressure

In the standard 25 C state, the air pressure is considered to be 1 atm, so the partial pressure of N₂ -nitrogen becomes:

Vn / Vtot = Pn / Ptot

78/100 = Pn / 1

Pn = 0.78 atm

Henry constant for N₂ at 25 °c = 1600 atm/mol.L=6.25.10⁻⁴ mol/L.atm

The solubility :

$\tt S=6.25.10^{-4}\times 0.78\\\\S=4.88\times 10^{-4}~mol/L$
