Hello!

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?

We have the following data:

P1 (initial pressure) = 12 atm

V1 (initial volume) = 23 L

T1 (initial temperature) = 200 K

P2 (final pressure) = 14 atm

T2 (final temperature) = 300 K

V2 (final volume) = ? (in L)

<u><em>Now, we apply the data of the variables above to the General Equation of Gases, let's see:</em></u>

\dfrac{P_1*V_1}{T_1} =\dfrac{P_2*V_2}{T_2}

\dfrac{12*23}{200} =\dfrac{14*V_2}{300}

\dfrac{276}{200} =\dfrac{14\:V_2}{300}

multiply the means by the extremes

200*14\:V_2 = 276*300

2800\:V_2 = 82800

V_2 = \dfrac{82800\!\!\!\!\!\!\!\dfrac{\hspace{0.4cm}}{~}}{2800\!\!\!\!\!\!\!\dfrac{\hspace{0.4cm}}{~}}

V_2 \approx 29.57142857... \to \boxed{\boxed{V_2 \approx 30\:L}}\:\:\:\:\:\:\bf\blue{\checkmark}

<u><em>*** Note: the approximation rule says that when the number before the digit 5 ​​is odd, the previous value is raised to the next even number</em></u>

<u><em>Answer:</em></u>

<u><em>The new volume is approximately 30 Liters </em></u>

Answer : The volume of gas will be 29.6 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 12 atm

P_2 = final pressure of gas = 14 atm

V_1 = initial volume of gas = 23 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 200K

T_2 = final temperature of gas = 300K

Now put all the given values in the above equation, we get the final pressure of gas.

\frac{12atm\times 23L}{200K}=\frac{14\times V_2}{300K}

V_2=29.6L

Therefore, the new volume of gas will be 29.6 L

Fofino [41]

Answer:

a) 2ZnS(s)+3O_2(g)\rightarrow 2ZnO(s)+2SO_2(g)

2 moles of Zinc sulphide in solid form reacts with 3 moles of Oxygen in gaseous form to give 2 moles of Zinc oxide in solid form and 2 moles of sulphur dioxide in gaseous form.

b)  CaH_2(s)+2H_2O(l)\rightarrow Ca(OH)_2 aq)+2H_2(g)

1 mole of calcium hydride in solid form reacts with 2 moles of liquid water to give 1 mole of calcium hydroxide dissolved in water and 2 moles of hydrogen in gaseous form.

The chemical reactions are written by writing the chemical formula of the reactants on left side of the arrow followed by chemical formula of the products. The number of atoms of each element must be balanced to follow the law of conservation of mass.

What mass of oxygen is needed to combust and produced 6.4 moles of carbon dioxide gas?
N76 [4]
You have already gotten the balanced equation. And the ratio of mol number of reactants and production is the ratio of coefficient. So there is 6.4/8*11=8.8 mol oxygen needed. The mass is 8.8*32=281.6 g.

Carbondioxide gas is't collectable in water. why​?
Lisa [10]

Answer:

carbon dioxide is a gas so it isn't collected over water.

Explanation:

it works for insoluble gases such as hydrogen,or gases that do not dissolve easily in water such as ammonia and chlorine are readily soluble in water and are not collected this way.

hope it is helpful for you.
