This question is very unspecific, but it is probably the Mantle. If that is wrong try Crust.<span />
The masses are always equal. Since matter can not be created nor destroyed, you will have the same amount of mass as you did before the reaction as you do after.
Explanation:
because metal want to give electron and nonmetal want to gain.
Answer:
Phosphorus makes 5 bonds with other atoms
Explanation:
has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).
These valence electrons are used to draw Lewis structure of
.
Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)
Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of
, it has been found that P makes total 5 bonds with rest of the atoms.
Lewis structure of
along with formal charge (in parentheses) has been given below.
