The rules of the atoms can be majorly explained through three rules and principles;
- Aufbau principle
- Pauli exclusion principle
- Hund's rule
Hund’s rule states that an atomic orbital is firstly singly occupied by electrons before it is doubly occupied until its fully filled. Electrons in a singly occupied orbital have the same spin quantum number.
Aufbau principle states that the lowest atomic orbitals are occupied first, while Pauli exclusion principle states that the electrons in an atomic orbital cannot have the same quantum state.
Answer:
light-dependant reactions and Calvin cycle:)
Explanation:
Well, In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Answer: Both Respiration and Burning uses oxygen. Both Respiration and Burning produces energy. Both Respiration and Burning gives out carbon dioxide as the end product.
Explanation: The overall chemical reactions of both Respiration and Burning are the same.
The correct answer for this question is "<span>The mass of the products equals the mass of the reactants because the same matter is present."
All chemical reactions follow the Law of Conservation of Mass which states that mass cannot be created nor destroyed. This means that mass is constant before and after a process. If ever it seems like the mass is not the same, it is possible that the missing mass was converted to something else.</span>
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
