How many water molecules are required in a chemical reaction?
Thus two molecules of hydrogen and one molecule of oxygen are needed to make two molecules of water. The reaction is accurately expressed by: There are now the same numbers of each type of atom on both sides of the equation: the chemical equation is balanced, so we can now replace the arrow with an equals sign.
How many water molecules are needed for the production of one molecule of glucose?
6 water water molecules
For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction. 6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.
How many molecules of H2O are needed for photosynthesis?
The Photosynthesis equation Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen and water.
How many molecules of glucose are produced in this chemical reaction?
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.
Why does it take 6 carbon dioxide and 6 water molecules to make one sugar molecule?
Why are six carbon dioxide molecules required to make one glucose molecule? Six carbon dioxide molecules (CO2) are required to create one glucose molecule (C6H12O6) because carbon dioxide has one carbon per molecule, while glucose molecules have six carbons.
How do plants make glucose during photosynthesis?
During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light. Photosynthesis requires energy to drive the chemical reaction. Photosynthesis is an endothermic reaction.
What is the chemical formula for photosynthesis?
The formula for photosynthesis is: 6CO2+12H2O → C6H12O6+6O2+6H2O I can count the carbons, the waters on the reactant side, the oxygens, and the glucose, but I cannot seem to locate where in either light or dark reaction 6 water molecules were produced again.
What are the two main reactions of photosynthesis?
Photosynthesis involves several different chemical reactions, but these can be summarised in two main stages. In the first reaction, energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product.
How is hydrogen used in the first stage of photosynthesis?
In the first reaction, energy is used to split water molecules into hydrogen and oxygen. The hydrogen is needed for the second stage of reactions and the oxygen is released by the plant as a waste product. In the reactions of the second stage, the hydrogen is combined with carbon dioxide to make glucose.
