Ammonium carbonate decomposes upon heating according to the following balanced equation:
(NH4)2CO3(s)?2NH3(g)+CO2(g)+H2O(g)< br />
Calculate the total volume of gas produced at 24.0?C and 1.05atm by the complete decomposition of 11.9g of ammonium carbonate

Answer : The total volume of gas produced are, 11.5 L

Explanation :

First we have to calculate the moles of ammonium carbonate.

Molar mass of = 96.094 g/mol

Now we have to calculate the moles of total gas.

The given balanced chemical reaction is:

From the balanced chemical reaction we conclude that,

As, 1 mole of react to give 4 mole of gas

So, 0.124 mole of react to give mole of gas

Now we have to calculate the volume of gas.

Using ideal gas equation:

where,

P = Pressure of gas = 1.05 atm

V = Volume of gas = ?

n = number of moles = 0.496 mole

R = Gas constant =

T = Temperature of gas =

Putting values in above equation, we get:

Thus, the total volume of gas produced are, 11.5 L

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
