Temperature of 1.4 moles of gas’s with pressure of 3.25 atmosphere in a 4.738-liter container

-139 °C

Step-by-step explanation:

We can use the Ideal Gas Law and solve for T.

pV = nRT     Divide each side by nR

 T = (pV)/(nR)

Data:  

p = 3.25 atm

V = 4.738 L

n = 1.4 mol

R = 0.082 06 L·atm·K⁻¹mol⁻¹

Calculation:

T = (3.25 ×4.738)/(1.4 × 0.082 06)

T =  134 K

T = (134 - 273.15) °C

T = -139 °C

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
