Using ideal gas equation,
PV=nRT
P=199 kpa
V=4.67 L
T=30+273K= 303K
n= number of moles of gas
R=8.321 L·kPa·K-1·mol-1
So using ideal gas equation,
n=PV/RT
=199*4.67/8.321*303\
=0.37 mol
Answer:
B
Explanation:
four electron in atom in cal
Answer:
1.59 atm
Explanation:
The reaction is:

The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:

we don't include
because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of
is:

from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of
.


The partial pressure of each gas is:


so total pressure is:

replacing the moles we get:

We know that T2=3*T1
replacing this value in the equation we get:
