Question

1.A sample of a gas occupies 3092 milliliters at
20.0±C and 4950 torr. What volume would it
occupy at the same temperature and 414 torr?
Answer in units of mL.


2. A 34 L tank contains a gas under a pressure
of 403 atm. What volume would the gas
occupy at the same temperature at 750 torr
of pressure? Answer in units of L.

Answer 1

Since the tempeature is constant in both your problems, all you need is the simple Boyle's Law equation

P1 V1 = P2 V2.

You question is relativley easy because you don;t have to change any units. Just plug the numbers in for each problem and solve for the new volume.

Answer 2

there's a undeniable quantity of reminiscence artwork to those. you're able to desire to bear in mind the names of the compounds or chemical species that type in a reaction with the intention to have the flexibility to write down the reaction out. you apart from mght might desire to bear in ideas the formula of the compounds you're speaking approximately. Potassium hydroxide is KOH and dissociates in water to grant a potassium io (ok+) and a hydroxide ion (OH-), so which you're able to write KOH(aq) ---> ok+(aq) + OH-(aq) the place the 'aq' only skill 'aqueous' or 'in water' For the rest, calcium hydroxide is Ca(OH)2 and could dissociate to grant a calcium ion (Ca++) and a pair of hydroxide ions. Sodium oxide is Na2O and could dissociate to grant 2 sodium ions (Na+) and one oxide ion (O=). The O= ion could on the instant react with a water molecule (H2O) to produce 2 hydroxide ions. Given this suggestion, i will bypass away it to you to write down out the wonderful chemical equations.
