Answer:

x=4

Explanation:

1.5(4+x)−3=4.5(x−2)

Step 1: Simplify both sides of the equation.

1.5(4+x)−3=4.5(x−2)

(1.5)(4)+(1.5)(x)+−3=(4.5)(x)+(4.5)(−2)(Distribute)

6+1.5x+−3=4.5x+−9

(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)

1.5x+3=4.5x−9

Step 2: Subtract 4.5x from both sides.

1.5x+3−4.5x=4.5x−9−4.5x

−3x+3=−9

Step 3: Subtract 3 from both sides.

−3x+3−3=−9−3

−3x=−12

Step 4: Divide both sides by -3.

−3x−3=−12−3

x=4

gavmur [86]

If the pressure is raised from 0.789 atm to 1.579 atm. Then the new volume of the CO₂ gas is 99.94 cubic mm.

<h3>What is thermodynamics?</h3>

It is a branch of science that deals with heat and work transfer.

The pressure on a 200-milliliter sample of co2 (g) at constant temperature is increased from 0.789 atm to 1.579 atm.

Then the new volume of the gas will be

For the constant temperature process, the formula we have

$\rm P_1V_1 = P_2V_2$

Then the new volume will be given as

$\rm V_2 = \dfrac{P_1V_1}{P_2}\\\\\\V_2 = \dfrac{0.789 \times 200}{1.579}\\\\\\V_2 = 99.93666 \approx 99.94 \ mm^3$

The immediate purpose of a scientific experiment is usually to... Question 20 options: solve a problem .... create monsters....

horsena [70]

The answer is test a hypothesis. You can't have a real scientific experiment without forming a hypothesis first. It also can't be creating monsters because that one doesn't make sense so we know that isn't correct. But based off the steps you have to take to perform a scientific experiment the answer would have to be to test a hypothesis.

Hope this helps ! <3
