Question

Consider the steps for the balancing of a chemical reaction. Identify the correct sequence.

(a) Check the correctness of the balanced equation.

(b) Make the list of number of atoms of different elements present in the unbalanced equation.

(c) Draw the boxes around each chemical formula (for compound/ element).

(d) Choose and balance the second element and so on.

(e) Start balancing from the compound which has more number of atoms and balance the first element.

(f) Write the symbols of physical states for compounds/ elements.

• A. e, d, a, f, b and c.
• B. e, d, b, a, f and c
• C. c, b, a, d, e and f
• D. c, b, e, d, a, and f

Answer 1

The correct option is D

c, b, e, d, a, and f

The correct order of the statements for balancing the chemical reaction is c, b, e, d, a, and f.
