How do I solve for V1 in this equation

arlik [135]

Answer:

<h2> $V_{1} = \frac{P_{2}V_{2}T_{1}}{P_{1}T_{2}}$ </h2>

Explanation:

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

<u>First of all cross multiply</u>

That's

$P_{1}V_{1}T_{2} = P_{2}V_{2}T_{1}$

<u>Next divide both sides by </u> $P_{1}T_{2}$ <u> in order to isolate </u> $V_{1}$

We have

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

We have the final answer as

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

Hope this helps you

In an experiment, what is the purpose of the control group?

Burka [1]

A control group is the comparison group that helps to "make sure your experiment works." A control group is separated from the rest of the experiment and nothing happens to it kinda like a controlled variable. Controlled variables are the variables in a experiment that remains the same for example a temperature, time, type of products, etc..

Hope this helps!

How much volume will 8.8 moles of gas fill at 0.12 atm at 56*C

Neporo4naja [7]

Answer:

2000 L

General Formulas and Concepts:

<u>Atomic Structure</u>

Moles
Temperature Conversion: K = °C + 273.15

<u>Gas Laws</u>

Ideal Gas Law: PV = nRT

P is pressure
V is volume (in L)
n is number of moles
R is gas constant
T is temperature (in K)

Explanation:

<u>Step 1: Define</u>

[Given] 8.8 moles gas

[Given] 0.12 atm

[Given] 56 °C = 329.15 K

<u>Step 2: Solve for </u><em><u>V</u></em>

Substitute in variables [Ideal Gas Law Formula]: $\displaystyle (0.12 \ atm)V = (8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)$
Isolate <em>V</em>: $\displaystyle V = \frac{(8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)}{(0.12 \ atm)}$
Multiply/Divide [Cancel out units]: $\displaystyle V = 1981.7 \ L$

<u>Step 3: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

1981.7 L ≈ 2000 L

How does frost form?

hram777 [196]

Answer:

Frost forms when an outside surface cools past the dew point.

Example: The dew point is the point where the air gets so cold, the water vapor in the atmosphere turns into liquid. This liquid freezes. If it gets cold enough, little bits of ice, or frost, form.
