What are the 3 kinds of solubility? Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble. Does base increase solubility? The anion in sparingly soluble salts is often the conjugate base of a weak acid that may become protonated in solution, so the solubility […]
Why is alkaline hydrolysis preferred?
Why is alkaline hydrolysis preferred? Hydrolysis using dilute alkali There are two big advantages of doing this rather than using a dilute acid. The reactions are one-way rather than reversible, and the products are easier to separate. Why is hydrolysis reversible? Hydrolysis is a reversible reaction, meaning that the alcohol and acid groups can react […]

Can a room be cooled indefinitely by leaving the door of the refrigerator open?
Can a room be cooled indefinitely by leaving the door of the refrigerator open? No, the room can’t be cooled by leaving the door of an electric refrigerator open. In fact the temperature of the room rises because the refrigerator extracts heat from the freezing chambers and rejects it to the surrounding air in the […]
When a metal jar lid is difficult to remove from a glass jar you can run hot water on the lid and then it is easier to open Why?
How breccia is formed?
How breccia is formed? Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. How hard […]

How does light interact with eyes?
How does light interact with eyes? Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The […]
What is the mechanical advantage of a simple block and tackle with one rope?
What is the mechanical advantage of a simple block and tackle with one rope? The mechanical advantage is 2, requiring a force of only 50 N to lift the load. How do you calculate the mechanical advantage of a mousetrap car? The total mechanical advantage can be calculated by multiplying the two: 1/6 x 1/19 […]
