Which element or elements are unbalanced in this equation?

mgo + 2 licl → mgcl2 + li2o

a)mg

b)li

c)all elements are balanced.

d)cl

option C = all elements are balanced

Explanation:

In given chemical equation all elements are balanced.

Chemical equation:

MgO + 2LiCl → MgCl₂ + Li₂O

This is balanced chemical equation. We can see that there are one Mg atom and one oxygen atom is present in reactant side and also in product side. So, both are balanced.

In case of lithium there are two Li atoms in reactant side and also in product side , it is also balanced.

There are two chlorine atoms are present in reactant side and also in product side. Chlorine atoms are balanced.

given the reactants, h2so4 and koh, we are asked to determine the product(s) of the reaction. since h2so4 is an acid and koh is a base. this is a neutralization reaction, thus, the products are salt and water. 

so, h+ from h2so4 will react with oh- from koh forming h2o. k+ will also react with so4 2- forming k2so4. therefore, the balanced reaction will be:

h2so4 + 2koh > k2so4 + 2h2o
