A mixture of co(g) and h2(g) is pumped into a previously evacuated 2l reaction vessel the total pressure of the reaction system
swat32

Answer is: total pressure of the system is 2.4 atm.

Boyle's Law (the pressure volume law): volume of a given amount of gas held  varies inversely with the applied pressure when the temperature and mass are constant.

p₁V₁ = p₂V₂ (the product of the initial volume and pressure is equal to the product of the volume and pressure after a change).

1.2 atm · 2 L = p₂ · 1 L.

p₂ = 1.2 atm · 2 L / 1 L.

p₂ = 2.4 atm.

When pressure goes up, volume goes down.  

When volume goes up, pressure goes down.

Caclulate the pH of a solution with a hydrogen ion concentration of 1X10-7
LUCKY_DIMON [66]

Answer:

The pH of the solution is 7.00 .

Explanation:

The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

pH = -log (H30 +)

pH= -log (1x10^-7)

<em>pH= 7.00</em>
