Question
Balance the following chemical equation.
\[\ce{NaCl + AgNO3 -> AgCl + NaNO3}\]
Advertisements
Solution
The number of atoms of elements in reactants and products is equal. It does not require any further balancing.
Since all the elements are balanced, the final balance equation is:
\[\ce{NaCl + AgNO3 -> AgCl + NaNO3}\]
The given equation is already balanced.

A student weighed some raisins and recorded the weight as ‘x’. She then soaked the raisins in distilled water. After about 2 hours she removed the raisins, wiped them dry and weighed them again, and recorded that as ‘y’. The percentage of water absorbed by raisins may be determined using the relationship.
In the experiment for determining the percentage of water absorbed by raisins, we do the final weighing of the raisins after keeping them dipped in water for about one hour. For the accuracy of the result, the extra water from the surface of the soaked raisins is removed by
