How can you identify a gas on a solubility curve? Solutes whose curves move downward with increased temperature are typically gases because the solubility of gases decreases with increased temperature. The steeper the incline of a solute, the more soluble the solute is because it doesn’t take as much of a temperature increase to dissolve […]
Can we see an atom yet?
Can we see an atom yet? Atoms are small. In fact, even the most powerful light-focusing microscopes can’t visualise single atoms. What makes an object visible is the way it deflects visible light waves. Atoms are so much smaller than the wavelength of visible light that the two don’t really interact. What is the meaning […]
What are the conditions to form ionic bonds?
What are the conditions to form ionic bonds? The Condition required for the formation of an ionic bond between two Elements are: Two elements must be of opposite charge. An element must have its less Ionisation Enthalpy(Cation). Another element must have high negative electron gain enthalpy(Anion). Which of the following is least ionic KCl AUCL? […]
What is the principle of naphthalene and salt?
What is the principle of naphthalene and salt? Answer: Sublimation is the method of separating naphthalene from common salt. Sublimation involves the conversion of a solid directly into its vapour state without being converted in the liquid state. Naphthalene vapours can be collected after sublimation and the salt remains as residue. Which method is used […]
What are the 7 steps of digestion?
What are the 7 steps of digestion? The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation. Some chemical digestion occurs in the mouth. Some absorption can occur in the mouth and stomach, for example, alcohol and aspirin. What is the first step in digestion process? Mouth. The mouth is the beginning […]
What is normal 10th physics?
What is normal 10th physics? An angle of refraction (r): It is the angle between refracted rays and perpendicular line (normal) at the point of incidence. “The incident ray, refracted ray and normal at the point of incidence all lie in the same plane.” Which is the most difficult chapter in class 10 science? Heredity […]
What is the formula of de Broglie wavelength?
Do polar or nonpolar compounds travel faster on silica gel?
Do polar or nonpolar compounds travel faster on silica gel? The solvent acts as the mobile phase along a polar paper stationary phase. Polar compounds will interact more with the paper, travelling slowly, while nonpolar compounds will interact more with the solvent, travelling more quickly. Is silica polar or nonpolar? Silica gel is a polar […]
What is the difference between a transverse wave and a longitudinal wave give examples of each?
What is the difference between a transverse wave and a longitudinal wave give examples of each? Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves. A sound […]
