Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

Halogens have a seven electrons in their outermost shell.
To complete the number of electrons in this shell, they need to gain an additional electron.
One more electron makes the halogen similar to the corresponding noble gas which is very stable.
Halogens are very reactive groups of elements and are highly electronegative.
They have a high affinity for electrons.
These elements are fluorine, chlorine, bromine, iodine and Astatine.

When molybdate (MoO3) and Zinc (Zn) are heated together they react in this equation:

schepotkina [342]

Answer: The mole ratio of Zn to ZnO is 3: 3.

Explanation:

According to law of conservation of mass, mass can be neither be created nor be destroyed. The mass on reactant side must be equal to the mass on product side. Thus the atoms of each element on both side of the reaction must be same.

The balanced chemical reaction is:

$3Zn+2MoO_3\rightarrow Mo_2O_3+3ZnO$
