Answer 1

To solve this question, you will need to match the coefficients of each of the chemical equations to make a balanced equation. A balanced equation is one in which the number of each type of atom on the left side of the arrow must equal the number of each type of atom on the right side of the arrow. The coefficients refer to the number of molecules that are needed to balance the equation. The correct coefficients for the equation provided are 1, 2, 1, 1. This means that for every 1 molecule of E2SO4, you need 2 molecules of SrCl2, 1 molecule of ECl, and 1 molecule of SrSO4 to make a balanced equation.
