How is science used in basketball? Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). The energy in the compressed air is transferred back to the ball pushing it back […]
What do polar solvents dissolve?
What do polar solvents dissolve? The rule of thumb is that “like dissolves like”. Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil. What are two factors that affect the solubility […]

How are alkali metals extracted?
How are alkali metals extracted? Alkali metals are generally extracted by electrolysis of their ores. Only electrolytic method is suitable because of high reactive nature of alkali metals. Why do alkali metals have low density? Since alkali metals have a large atomic size and low atomic weight, they have low density. What are the properties […]
