Is this the same question that I have solved yesterday?

"

The Ideal Gas Law states that PV=nRT where P is pressure, V is volume, n is number of molecules, R is the gas constant and T is the temp.

As temp does not change and pressure does not change, we move the constants to one side: V/n=RT/P=constant.

We get V1/n1=V2/n2

n1=352 milimoles

n2=352+100=452 millimoles

V2=n2*V1/n1=452*25.2/352

=32.36mL

"

If so, you can report this question. A moderator will delete it and you can get your points back.

avogadros law states that under constant temp n pressure, volume of a gas is directly proportional to amount of gas

amount of gas1 = 352millimoles

amount of gas2 = 352+100 = 452millimoles

new vol = old vol x 452/352 = 25.2 x 452/352

= 32.4 mL

Why does the electrical conductivity of ionic compounds change when they are dissolved in water?
meriva
Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution. Electrical conductivity of the compound in liquid form

What coefficient for O2 demonstrates the law of conservation of mass?
olga2289 [7]

Answer:

2

Explanation:

The coefficient for O is 2 and this is an example of a combustion reaction. With the help of the coefficient 2 infront of oxygen, this equation now demonstrates law of conservation of mass.
