aThe oxygen atom of the water molecule is more electronegative than the hydrogen atom (i.e., it attracts more the electrons). As a result, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole.[translate]...
Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...

To understand why the oxygen molecule (O₂) is diatomic while the sulfur molecule (S₈) is octatomic, we can break down the explanation into several key points: 1. Atomic Size Comparison: - Oxygen (O) has a smaller atomic size compared to sulfur (S). Both elements belong to Group ...
What molecule is regenerated during the process of the Krebs cycle? Photosynthesis is a redox reaction. Which of the following is oxidized during the process? a. carbon dioxide b. water c. carbohydrate d. oxygen If glucose has undergone oxidation, it has done what? Which kind of reaction con...
What molecule does aerobic respiration use that anaerobic respiration is missing? (a) oxygen (b) glucose (c) exercise (d) light Cellular Respiration: Cellular respiration is the process by which energy (in the form of ATP) is generated inside cell...
