It has 4 because electrons are negative.
Answer:
Specific heat is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in temperature.
Explanation:
I searched for complete question (as your question is missing with structure) and found the structure of compound attached below.
Answer: The compound can
neither act as a Hydrogen Bond Donor
nor act as a Hydrogen Bond Acceptor.
Explanation: For two compounds to build Hydrogen Bond Interactions it is compulsory that they must contain Hydrogen atoms which are directly attached to most electronegative atoms like
Fluorine,
Oxygen and
Nitrogen.
As the given compound is
2-Butene (a non polar hydrocarbon), it lacks partial positive Hydrogen (which can act as Hydrogen Bond Donor) and a most electronegative element (F, O or N) which can act as Hydrogen Bond Acceptor. Therefore, this compound will not generate any Hydrogen Bonding with water molecules and will remain immiscible in it.
These are 3 assumptions that i know for a fact. Hope this helped.
1.Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.
2.There are no forces of attraction between gas particles.
3.The temperature of a gas depends on the average kinetic energy of the particles of the gas.
