We can characterize properties of a substance to identify it because it helps us determine how the substance should be used. We can identify a substance by using physical or chemical properties. These help us by telling us which chemical we are looking at.

I hope this helps.. I wasn't sure what kind of answer you were looking for.

Imagine that you have a 5.00 LL gas tank and a 4.50 LL gas tank. You need to fill one tank with oxygen and the other with acetyl

Otrada [13]

Answer:

$P_2=139atm$

Explanation:

Hello,

In this case, even we are given two different gases, as it says "ensure that you run out of each gas at the same time", they shall behave as only one, for that reason, no matter the amounts, they are going to be modeled by means of the Boyle's law, as temperature remains unchanged, which allows us to understand the pressure-volume behavior as an inversely proportional relationship:

$P_1V_1=P_2V_2$

Hence, we solve for the P2, representing the pressure of the acetylene as shown below:

$P_2=\frac{P_1V_1}{V_2} =\frac{5.00L*125atm}{4.50L} \\\\P_2=139atm$

Best regards.
