Answer:
sugar
Explanation:
sand will not dissolve in water because the bond in water isn't strong enough to dissolve it.
so sand is a big no.
so the answer is the other option: which is sugar.
Answer: The partial pressure of is 0.35 atm.
Explanation:
Given: Total pressure = 0.98 atm
Partial pressure of = 0.48 atm
Partial pressure of Ar = 0.15 atm
Partial pressure of = ?
Total pressure is the sum of partial pressure of each component present in a mixture of gases.
Hence, partial pressure of is calculated as follows.
Total pressure =
Substitute the values into above formula as follows.
Thus, we can conclude that the partial pressure of is 0.35 atm.
Gas is one of the four fundamental states of matter
Answer:
Tthe value of
Explanation:
Initial moles of hydrogen peroxide = 1.75 mole
Volume of the container = 25 L
Concentration of a substance is calculated by:
So, concentration of hydrogen peroxide =
The given chemical equation follows:
Initially 0.07 M 0 0
At equilibrium
(0.07-2x) M 2x x
We are given:
Equilibrium moles of hydrogen peroxide = 1.20 mole
Equilibrium concentration of hydrogen peroxide =
Evaluating the value of 'x', we get:
(0.07-2x) M = 0.048 M
x = 0.011 M
So, the equilibrium concentrations of water vapors and oxygen gas are:
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of
