A 7.0 L sample of methane gas is collected at 50.0°C.
Predict the volume of the sample at 0°C.

V₂ = 5.92 L

Explanation:

Given data:

Initial volume of methane = 7.0 L

Initial temperature = 50.0°C

Final temperature = 0°C

Final volume = ?

Solution:

Initial temperature = 50.0°C (50+273 = 323 K)

Final temperature = 0°C (0+273 = 273 K)

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 7 L × 273 K / 323 k

V₂ = 1911 L.K / 323 K

V₂ = 5.92 L

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
