1. A gas has an initial volume of 13 L at a pressure of 1.8 atm. What will be the new pressure at a volume of 5 L?

Hey there!:

The law of boyle is used:

initial pressure ( P1 ) = ?

initial volume ( V1 ) = 13 L

final pressure ( P2 ) = 1.8 atm

final volme ( V2 ) =  5 L

P1 *V1 = P2 * V2

P1 * 13 = 1.8 * 5

P1 * 13 = 9

P1 = 9 / 13

P1  = 0.692 atm

Hope this helps!

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
