Explanation :
Balanced reaction : It is defined as the reaction in which the atoms of individual element present on reaction side must be equal to the product side.
As we are given that:
A smoothie contains 1 banana (B), 4 strawberries (St), 1 container of yogurt (Y), and 3 ice cubes (lc).
The balanced chemical equation will be:
![1B+4St+1Y+3Ic\rightarrow BSt_4YIc_3](https://img.qammunity.org/2021/formulas/chemistry/middle-school/q5q8y5mziqtskk99dx27g74u2a29luxz3w.png)
