What would be the change in pressure in a sealed 10.0 l vessel due to the formation of n2 gas when the ammonium nitrite in 2.40 l of 0.900 m nh4no2 decomposes at 25.0°c?

Answer : The pressure of the gas will be, 5.285 atm

Solution : Given,

Volume of gas = 10 L

Temperature of gas =  

Volume of = 2.40 L

Molarity of the ammonium nitrate solution = 0.9 M

First we have to calculate the moles of ammonium nitrate.

The balanced chemical reaction is,

From the balanced reaction, we conclude that

1 mole of decomposes to give 1 mole of gas

2.16 moles of decomposes to give 2.16 moles of gas

Now we have to calculate the pressure of the gas.

using ideal gas equation,

where,

P = pressure of the gas

V = volume of the gas

T= temperature of the gas

n = number of moles of gas

R = gas constant = 0.0821 Latm/moleK

Now put all the given values in ideal gas equation, we get pressure of the gas.

Therefore, the pressure of the gas will be, 5.285 atm

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
