Answer:
Explanation:
Partial pressure of oil = mole fraction of oil x total pressure
mole fraction of oil = mole of oil / mole of water + mole of oil
= mole of oil = mass of oil / molecular weight of oil
= 20 / 100 = .2
mole of water = 80 / 18
= 4.444
mole fraction of oil = .2 / .2 + 4.444
= .2 / 4.644
Partial pressure of oil = mole fraction of oil x total pressure
= (.2 / 4.644 ) x 760 mm
= 32.73 mm Hg .
An example is when on a seesaw if a kid is on one side and an adult is on the other then it is unbalanced because the adult weighs more
A change of one unit on the pH scale represents a change in the concentration of hydrogen ions by a factor of 10, a change in two units represents a change in the concentration of hydrogen ions by a factor of 100. Thus, small changes in pH represent large changes in the concentrations of hydrogen ions.
Options if it’s true or false true
Im not sure how correct these are but i hope they help :)
some potential barriers are
youd have to wait for the chemicals to clear up before goiun gback into that room if u have kids that r little you would have to make sure they dont lick wutever it is u cleaned otherwise it might poison them and if u use to much of it it could make the air poisoness for a few which could be dangerous toi breathe in.
again im not to sure how correct these r but i hope they were right and i hope they help :)
