Answer:
K = 137.55 atm/M.
Explanation:
- The relationship between gas pressure and the concentration of dissolved gas is given by Henry’s law:
<em>P = (K)(C)</em>
where P is the partial pressure of the gaseous solute above the solution (P = 1.0 atm).
k is a constant (Henry’s constant).
C is the concentration of the dissolved gas (C = 7.27 x 10⁻³ M).
∴ K = P/C = (1.0 atm)/(7.27 x 10⁻³ M) = 137.55 atm/M.
<u>Answer:</u>
<em>A - It will increase</em>
<em></em>
<u>Explanation:</u>
Take for instance,
The number of particles (10000) present initially is less in a per unit volume say in 1 mL.
The number of particles increases (20000) in the same volume 1mL
.
So, the pressure will increase in the container since 10000 particles is present in a low volume of 0.5 mL now.
We know as volume decreases the pressure will increase as per Boyle’s law.

The formula of the product when Br2 reacts with 3L of F2 to completion and produce 2 L of the product is
2 BrF3
Br2 +3F2 = 2BrF3
1 mole of Br reacted 3 moles of f2 to form 2 moles of BrF3
Answer:
No.
Explanation:
This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.
<span>If the decomposition of H2O2 is first order, then
rate=k*[H2O2], and k=rate/[H2O2]
In this case k=(4.83 x 10-6 M/s)/(0.15 M)
k=3.22 x 10-5 s^-1</span>
