Answer:
x=170
The question is asking you to add them together to get your unknown number
<u>We are given:</u>
V1 = 100 mL P1 = 6 atm
V2 = x mL P2 = 1 atm
<u>Solving for 'x' : </u>
According to the Boyle's law:
P ∝ 1/V (pressure and volume are inversely proportional)
PV = k (where k is a constant)
since the constant k will be the same:
P1V1 = P2V2
replacing the variables
6 * 100 = 1 * x
x = 600 mL OR 0.6L
Therefore, the gas will have a volume of 600mL or 0.6L
Answer:
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Given: Kc = 0.50
Temperature = ![400^oC=[400+273]K=673K](https://tex.z-dn.net/?f=400%5EoC%3D%5B400%2B273%5DK%3D673K)
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(3+1) = -2
Thus, Kp is:
Answer:
pH = 3.65
Explanation:
given data
pKa of HNO2 = 3.40
nitrous acid (HNO2) = 0.110 M
NaNO2 = 0.200 M
to find out
What is the pH
solution
we get here ph for acidic buffer that is express as
pH = pKa + log(salt÷acid) ........................1
put here value and we get
pH = 3.40 + log(0.200÷0.110)
pH = 3.65
Liquid silver is less dense than solid silver, so the solid silver would sink
