Carbon, helium, and sodium are monoatomic elements.
Hydrogen, iodine, and oxygen are diatomic elements.
Using the ideal gas equation:
pV = nRT
n = pV / RT
1atm = 101325Pa, so p = 10132500Pa
1L = 0.001m^3, so V = 0.050m^3
R = 8.214 (ideal gas constant)
T = 273K
Hence moles of CO2 = (10132500 * 0.050) / (8.314 * 273) = 223.2101553
Reaction ratio between oxygen and CO2 is 1:2
Hence moles of O2 = 223... / 2 = 112 moles (3sf)
C.) a substance with a low ability to conduct energy
Explanation:
The statement that best defines insulators is that it is a substance that has low ability to conduct energy.
Insulators resist the movement of mostly electrical and thermal energy.
They have unique properties that makes them so.
- Insulators are substances that do not conduct heat and electricity.
- Both their solid and molten form lacks the capability of electrical and thermal conduction.
- Some substances can only conduct when molten or liquid.
- Conductors are materials that allows for the passage of electrical and heat energy.
- Most conductors are usually salts, ionic compounds and metals.
- Non-conductors like insulators are usually plastics and woods.
