Is oxygen considered a product?
Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Is a reactant or product?
The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. A product is a substance that is present at the end of a chemical reaction.
How many reactants and products are in oxygen?
Element-reactant-product table
| Element | Number of reactants | Number of products |
|---|---|---|
| Hydrogen | 5 | 5 |
| Carbon | 3 | 3 |
| Oxygen | 5 | 5 |
| Sodium | 1 | 1 |
What is considered a reactant?
Reactant: Any entity whose chemical structure is changed in a chemical reaction or mechanism step. Even though their chemical structure may change (and then be restored) during the course of a reaction or mechanism step, catalysts are usually not considered to be reactants.
How many atoms of oxygen are present in the reactants?
two oxygen atoms
There are two oxygen atoms in the reactants and two atoms of oxygen in the product. The law of conservation of matter has been satisfied.
What is the example of reactant?
Examples of Reactants H2 (hydrogen gas) and O2 (oxygen gas) are reactants in the reaction that forms liquid water: 2 H2(g) + O2(g) → 2 H2O(l). Notice mass is conserved in this equation. There are four atoms of hydrogen in both the reactant and product side of the equation and two atoms of oxygen.
Is oxygen compound or an element?
Oxygen is a chemical element with symbol O and atomic number 8. Classified as a nonmetal, Oxygen is a gas at room temperature.
