phosphorus in water is rapid combustion.
Answer:
C.
Explanation: In nuclear fission and fusion reactions, some of the energy in matter is converted to energy. If you weigh the reactants and the products, the products will weigh less than the reactants. This is called the mass defect and is the result of turning matter into energy.
Answer:
A covalent chemical bond is one in which <u>outer-shell electrons of two atoms are shared so as to satisfactorily fill their respective orbitals</u>.
Explanation:
Covalent bonds are formed between two atoms having their electronegativity difference less than 1.7. In this type of bonding the valence electrons of one atoms forms molecular bond with the valence electrons of another atom. The electrons are mutually shared.
Covalent bond can be non-polar as for example formed between hydrogen and carbon atoms.
Also, covalent bond can be polar in nature as that formed between hydrogen and chlorine atoms because the chlorine atom is more electronegative and hence attracts the electrons more towards itself making density of electrons less on hydrogen atom.
When nuclear fusion reaction takes place, matter is converted to energy.
