A gas gas a volume of 4.0 liters at a pressure of 0.80 atm. What is the volume if the pressure is changed to 0.40 atm at a constant temp

The volume is 8,0 L.

Explanation:

We apply Boyle Mariotte's Law: for a given mass of gas at constant temperature, its pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa):

P1 x V1 = P2 xV2

V2 = (P1 x V1)/P2

V2 = ( 0,80 atm x 4,0 L)/ 0,40 atm

V2= 8,0 L

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
