The chemical equation given below represents the chemical reaction between lithium (li) and sulfur (s). in the equation, why is the number 2 present in front of lithium on the reactants side of the equation?
a. to show the number of lithium atoms involved in the reaction
b. to show the number of electrons gained by lithium in the reaction
c. to show the atomic number of lithium in the periodic table
d. to show the number of electrons lost by lithium in the reaction

Option (A) is the correct answer.

Explanation:

The given chemical reaction equation is as follows.

As the number of atoms on both reactant and product side are the same. Hence, it is a balanced chemical reaction equation.

Here, number 2 before lithium atom represents that two atoms of lithium are taking part in the reaction. As there is no coefficient or number placed before the sulfur atom this means that only one atom of sulfur is reacting in the reaction.

Thus, we can conclude that the number 2 present in front of lithium on the reactants side of the equation shows the number of lithium atoms involved in the reaction.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
