However, we use the formulas in equations to represent elements and compounds. If we put a number (a coefficient) in front of the formula, we are simply using a different amount of the same substance. If we change the subscript in the formula, we are changing the substance .... Nov 07, 2019 · The balanced equation is: 2 Fe 2 O 3 + 3 C → 4 Fe + 3 CO 2. Both the left and right sides of the equation have 4 Fe, 6 O, and 3 C atoms. When you balance equations, it's a good idea to check your work by multiplying the subscript of each atom by the coefficient. When no subscript is cited, consider it to be 1.. Now look at the O atoms. They are not balanced. There are 2 O atoms on the left side and 4 on the right. Place a coefficient of 2 in front of the O2. We now have 4 O atoms on both sides. CH4 + 2O2 → CO2 + 2H2O. The equation is now balanced. Each side has 1 C atom, 4 H atoms, and 4 O atoms. Answer link. You balance a chemical equation by adding coefficients in front of the chemical formulas. Never change the subscripts because that would change the chemical formula. Write a balanced chemical equation for the following reaction. Change the words into correct formulas. The balancer is case sensitive. Use uppercase for the first character in the element and lowercase for the second character. When the following equation is balanced, the coefficient of H2SO4 IS _____ H2SO4 (aq) + NaOH (aq) Na2SO4 (aq) + H2O (l) 3. Note: You could have written a balanced equation using multiples of the coefficients. For example, if you double all of the coefficients, you still have a balanced equation: 8 Fe + 6 O 2 → 4 Fe 2 O 3. However, chemists always write the simplest equation, so check your work to make sure you can't reduce your coefficients. a) Which of the following are coefficients you could use in a balanced equation? Only whole numbers ☐½ ☐¾ ☐1 ☐2 ☐6 ☐9 b) If you were balancing an equation containing the O2molecule, which of the following would be correct representations of O 2and its coefficient? ☐½O2 ☐O2 ☐3O2 ☐6O2 ☐3O ☐5O3 ½O 2 ☐ O 4.
