Answers

Answer:

If I had to choose I think it would be humans fault.

Explanation:

To think that we are the reason for global warming and everything would make the next person a little insulted but when you think about it a long time ago when there was not many technological advancements there was not complains of global warming or anything until recently. Temperatures are starting to rise and more and more pollution is filling our atmosphere. As it could be true that it might not be entirely our fault as humans I think we took a major part in it.

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?

Answers

Answer:

V₂ = 236.84 mL

Explanation:

The relation between pressure and volume is inverse.

We can write it as follows :

[tex]P_1V_1=P_2V_2[/tex]

We have,

P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.

So,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]

So, the new volume of the gas is 236.84 mL.

Tenemos la ecuación de la reacción como sigue;

 N2 (g) + 2 O2 (g) → 2 NO2 (g)

Asi que;

Si 1 mol de nitrógeno produce 2 moles de NO2

5 moles de nitrógeno producirán 5 * 2/1 = 10

Por tanto, se producen 10 moles de NO2 moles
