According to Boyle’s law, PV= K, what was the volume at the time of the first measurement given the following information? Round
Temka [501]
<h2>Hello!</h2>

The answer is:

The first measurement of volume is equal to 835.23 mL.

<h2>Why?</h2>

Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.

So, we Boyle's Law equation states that:

P_{1}V_{1}=P_{2}V_{2}

Where,

P_1=FirstPressure\\V_1=FirstVolume\\P_2=NewPressure\\V_2=NewVolume

Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:

P_{1}V_{1}=P_{2}V_{2}\\\\V_{1}=\frac{P_{2}V_{2}}{P_{1}}

So, substituting the given information and calculating, we have:

V_{1}=\frac{8.59atm*527mL}{5.42atm}

V_{1}=\frac{4526.93atm.mL}{5.42atm}=835.23mL

Hence, the first measurement of volume is equal 835.23 mL.

Have a nice day!

Find the product of ( 2a2– 3b2) and ( a +b2- 3z)​
Bond [772]

Answer:

2a^3+2a^2b^2-6a^2z-3ab^2-3b^4+9b^2z

Step-by-step explanation:

(2a^2-3b^2)(a+b^2-3z)

Start by distributing the 2a^2 into all of the terms in between the second parentheses.

2a^3+2a^2b^2-6a^2z

Next, distribute the -3b^2 into all of the terms in between the second parentheses.

-3ab^2-3b^4+9b^2z

For the sake of simpler interpretation, I separated the two above, but they are together:

2a^3+2a^2b^2-6a^2z-3ab^2-3b^4+9b^2z

Since the terms are already in descending order, we do not need to rearrange them.

What’s the volume of the prism
likoan [24]

Answer:

384 cubic inches (in^3)

Step-by-step explanation:

volume = length * width * height

So find the volume of the large rectangle of the prism, then find the volume of the small rectangle of the prism. Add the two volumes together and the sum is your final answer.
