Though helium doesn't usually react with other substances due to its full electron shell, it doesn't mean it lacks chemical properties. Properties like atomic number, atomic mass, density, and reactivity are its chemical properties.
The statement that helium does not usually react with other substances is correct. This is due to helium being a noble gas with a complete set of electrons in its outer shell, making it stable and unlikely to participate in chemical reactions. However, this does not mean it has no chemical properties. Properties such as atomic number, atomic mass, density, and the inability to react or bond with other elements are indeed chemical properties.

Answer:
-232 °C
Explanation:
We can use the Ideal Gas Law and solve for T.
pV = nRT
Data:
m = 20.0 g
p = 6.0 atm
V = 0.40 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
Calculations:
1. Moles of N₂
2. Temperature of N₂
3. Convert the temperature to Celsius
T = (41.0 - 273.15) °C = -232 °C
Hey there. I did not build a model for you. Below is a picture of a Plant Cell that you could get some ideas from.
Best Of Luck,

A plant cell is a type of cell found in green plants that is responsible for photosynthesis. It contains a cell wall, chloroplasts, and a central vacuole, which distinguish it from animal cells. Plant cells also include plastids and typically do not have lysosomes or centrosomes.
