Handle of frying pan would be a
good use for a nonmetal. A nonmetal is neither a good thermal insulator nor a
good electrical conductor. Because it is neither, it can be use as a semiconductor.
It does not absorb heat that much that is why it is best in insulating.
All the elements in one group have the same number of valence electrons.
Answer:
yes
Explanation:
the results are CO2 and H2O, which usually appear after some kind of combustion.(combustion=burning)
hope this helps!
Explanation:
Molar heat combustion:
Molar heat of combustion is defined as heat released when 1 mole of substance is burnt under the action of oxygen gas to give water and carbon-dioxide.It is measured in kiloJoules (kJ) per mole.This heat of energy can be positive or negative.
- If the enthalpy is positive than the reaction is said to be an endothermic reaction.
- If the enthalpy is negative than the reaction is said to be an exothermic reaction.
