![]() ![]() If an element appears in more than one formula on a given side of the equation, the number of atoms represented in each must be computed and then added together. Welcome to Its Elemental - Balancing Act The computer will give you a number of incomplete chemical equations. Note that the number of atoms for a given element is calculated by multiplying the coefficient of any formula containing that element by the element’s subscript in the formula. It may be confirmed by simply summing the numbers of atoms on either side of the arrow and comparing these sums to ensure they are equal. ![]() To do this, keep in mind a subscript indicates the number of atoms. The space shuttle had to be designed to carry 0.126 tn of H 2 for each 1.00 tn of O 2. ![]() Finally, convert the mass of H2 to the desired units (tons) by using the appropriate conversion factors: tonsH2 1.14 × 105gH2 × 1lb 453.6g × 1tn 2000lb 0.126tnH2. This is a requirement the equation must satisfy to be consistent with the law of conservation of matter. Balancing Chemical Equations X + Y XY Introduction Game. The next step for balancing the chemical equation is to determine how many atoms of each element are present on each side of the arrow: Fe + O 2 Fe 2 O 3. massofH2 5.66 × 104molH2 × 2.016gH2 molH2 1.14 × 105gH2. \) is balanced, meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides. ![]()
