When writing chemical equations, the coefficient is distributed to each element in the (1) not just the first element. The coefficient also goes in front of the entire compound. If a subscript is located within the compound, the subscript is (2) by the coefficient to determine the number of atoms of that element. Examine the formula: N2 + H2 ⇒ NH3. When balancing this equation, the reactant side has (3) nitrogen atoms, while the product side has (4) nitrogen atom. To balance the nitrogen atoms, a coefficient of 2 is placed in front of the compound (5) . The number of hydrogen atoms in the product is now equal to 2x3, or the coefficient times the (6) . The hydrogen atoms on the reactant and product sides are not (7) . To balance them, a (8) must be placed in front of the H2. Now the equation is balanced. Options:
(1) - Balanced, Compound, Subscript
(2) - Subscript, Balanced, Compound, Multiplied
(3) - 2, 1, 3, N2
(4) - 3, H2, 2, 1
(5) - N2, NH3, H2, 2
(6) - Subscript, Compound, Balanced, Multiplied
(7) - Subscript, Compound, Balanced, Multiplied
(8) - 2, 1, H2, 3
