Which polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1

kolezko [41]

Answer:

"Nitrate" is a polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1

Explanation:

Nitrate is a polyatomic ion with the molecular formula NO⁻ ₃. Organic complexes that comprise the nitrate ester as a functional group are also named nitrates. Nitrates are shared apparatuses of fertilizers and explosives. Almost all nitrate salts are soluble in water. Usually nitrates that enter the body by eating or drinking leave the body without harm. These nitrites in the blood cause changes in hemoglobin, or the molecules that help move oxygen in the body. Nitrates can make it so that less oxygen is available for the body to function properly.

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 :

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