The deposits from volcanoes can also be used for building materials. Volcanic explosions have caused the atmosphere and oceans to form. Volcanic deposits also create land which is fertile.
Answer:
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium's noble gas configuration becomes [Ne]3s1. That is the answer.

Answer:
True
Explanation:
Limiting reactant - the reactant which get completely consumed in a chemical reaction , is known as the limiting reactant .
As, the concentration of limiting reactant after the completion of the reaction will be zero , hence, it is used to determine the concentration of other reactants .
For example,
for a general reaction -
A + B ---> 3C
Assuming B to be the limiting reactant ,
hence, the concentration of C and A can be determined as -
1 mol of B can give 3 mol of C and 1 mol of A is used for the reaction.
