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.

2.carbon dioxide

3.helium

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.
