Is calcium fluoride acidic or basic?
Is calcium fluoride acidic or basic? CaF2 is slightly basic. The reason is HF is a weak acid ( but it is very corrosive). When dissolved in water, the F- ion formed will undergoes hydrolysis reaction with water molecules forming HF and OH-. Thats why, it is basic. Does calcium fluoride dissolved in water? Calcium […]
How does precipitation affect the weather?
How does precipitation affect the weather? Global Climate Change. comes from precipitation. Too little precipitation can result in dry soil, shallow streams, and shortages of municipal water supplies. For example, too much rain or snowmelt (water from melted snow) at one time can lead to flooding. How is rainfall helpful? Rain and snow are key […]
Why are finches in the Galapagos Island A good example of speciation?
Why are finches in the Galapagos Island A good example of speciation? All the finches in the different islands share a common ancestor, which is a group of finches that initially migrated into the islands and conquered the different islands. Due to the different ecologies in the different islands, adaptive radiation of the finches occurred […]

Does convex lens converge light rays?
Does convex lens converge light rays? Because a convex lens concentrates the light rays that are incident on it, it is called a converging lens. The bending of rays is maximal at the top and bottom of the lens. The distance from the optical center to the focal point is called the focal length of […]
Which bulb will glow brighter in series?
Which bulb will glow brighter in series? Key Points: In a series circuit, 80W bulb glows brighter due to high power dissipation instead of a 100W bulb. In a parallel circuit, 100W bulb glows brighter due to high power dissipation instead of an 80W bulb. The bulb which dissipates more power will glow brighter. What […]
What is variable and example?
What is variable and example? In mathematics, a variable is a symbol or letter, such as “x” or “y,” that represents a value. For example, in the equation below, y is the “dependent variable” because its value is based on the value assigned to the “independent variable” x. … What are some limitations in qualitative […]
