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 […]

Which of the following elements is the most reactive Cl Br or I?
Which of the following elements is the most reactive Cl Br or I? 1 Expert Answer Mike – I can tell you the order of reactivity for these specific nonmetals, I<Br<Cl, therefore, Cl is the most reactive nonmetal in this list. Is nitrogen gas heavier than oxygen? Oxygen is denser than both air and nitrogen, […]
How do I make my plants more green?
How do I make my plants more green? Magnesium in the Epsom salt plays a very crucial role in photosynthesis which is used by the plants to convert sunlight into food. The photosynthesis process creates chlorophyll which is the pigment that gives green plants and algae their color. Are yellow leaves a sign of overwatering? […]
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 […]

Are temperature and moles directly proportional?
Are temperature and moles directly proportional? At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. What happens to pressure when volume and temperature decrease? […]
What are two properties of oxygen?
What are two properties of oxygen? The Physical Properties of Oxygen are as follows: Color : Colorless. Phase : Gas. Odor : Oxygen is an odorless gas. Taste : A tasteless gas. Conductivity : A poor conductor of heat and electricity. Solubility : Slightly soluble in water, alcohol and some other common liquids. Density : […]
How is science used in basketball?
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 […]
Which of these is an example of negative reinforcement?
Which of these is an example of negative reinforcement? Deciding to take an antacid before you indulge in a spicy meal is an example of negative reinforcement. You engage in an action in order to avoid a negative result. One of the best ways to remember negative reinforcement is to think of it as something […]
