Answer:
i think it is all atoms of all elements are exactly alike and have the same mass
Explanation:
Answer:
P = 162 KPa
Explanation:
Given data:
Number of moles = 2 mol
Volume of gas = 30.0 L
Temperature of gas = 293 K
Pressure of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
P = nRT/V
P = 2 mol ×0.0821 atm.L/ mol.K ×293 K/ 30.0 L
P = 48.11 atm.L/ 30.0 L
P = 1.6 atm
atm to kelvin:
1.6×101 = 162 KPa
Answer:
a) 0.30
Explanation:
Kc = [C] [D] / ([A] [B])
Set up an ICE table:
![\left[\begin{array}{cccc}&Initial&Change&Equilibrium\\A&0.4&-x&0.4-x\\B&0.4&-x&0.4-x\\C&0&+x&x\\D&0&+x&x\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%26Initial%26Change%26Equilibrium%5C%5CA%260.4%26-x%260.4-x%5C%5CB%260.4%26-x%260.4-x%5C%5CC%260%26%2Bx%26x%5C%5CD%260%26%2Bx%26x%5Cend%7Barray%7D%5Cright%5D)
Plug in values and solve:
9 = x² / (0.4 − x)²
3 = x / (0.4 − x)
1.2 − 3x = x
1.2 = 4x
x = 0.3
