WebOct 2, 2024 · A balanced equation contains the same number of each type of atoms on both the left and right sides of the reaction arrow. To write a balanced equation, the reactants go on the left side of the arrow, while the products go on the right side of the arrow. Coefficients (number in front of a chemical formula) indicate moles of a compound. Weba. whether a certain displacement reaction can occur. b. whether a chemical reaction will absorb energy. c. the state of a product. d. the melting points of elements. b. if metal A is placed in an ionic solution containing metal B ions and no reaction occurs, then metal B is most likely: a. a halogen. b. higher on the activity series.
WebOct 24, 2024 · Explanation In words, the equation may be stated as: Six carbon dioxide molecules and six water molecules react to produce one glucose molecule and six oxygen molecules . The reaction requires energy in the form of light to overcome the activation energy needed for the reaction to proceed. WebThe overall chemical equation says that 1 mole of glucose reacts with 6 moles of oxygen gas for the reaction to occur. So the glucose to oxygen ratio is 1:6, or basically we need 6 times as many moles of oxygen gas as we do glucose for the reaction to happen. So 0.129 x 6 = 0.833 moles of oxygen. Hope that helps.
