ANSWER:

Solution 37P

Here, we have to write the balanced equations for each of the following by inserting the correct coefficients in the blanks.

Step 1 of 2

Rules for balance the chemical equations is as follows.

  • Write the reactants and products using the correct formula and state for each substance.
  • Count the number of each atoms of each element on the LHS of the equation.
  • Do the same for RHS compare for each element.
  • And write the correct coefficients for that make the equation balanced.
