What is the difference between a hydrogen ion and a hydroxide ion? A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. Because the base “soaks up” hydrogen ions, the result is a solution with more hydroxide […]

What is a persons carbon footprint? A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Why is it important to reduce […]

How does the rate of cooling affects the crystal size? It can be used to illustrate how the rate at which molten rock cools affects the size of the crystals that form within the solid rock – If the magma cools quickly, the crystals do not have much time to form, so they are very […]

Who created the boogaloo dance? Use of the term boogaloo in referring to a musical style was probably coined in about 1966 by Richie Ray and Bobby Cruz. The biggest boogaloo hit of the ’60s was “Bang Bang” by the Joe Cuba Sextet, which sold over one million copies in 1966. “El Pito” was another […]

Are vectors hard? However, perhaps in standard mathematical curricula, vectors just happen to be the first such “interesting” object which students encounter. After having spent (presumably) more than a decade of being taught mathematics in a very rigid and well-defined way, that’s a pretty tough gear-change to make. Is physics grade 12 hard? Physics is […]

What causes light rays to bend in a new medium? When light rays enter a new medium at an angle, the change in speed causes them to bend and change direction. They change the speed causes the ray to bend or change direction. When light slows down even more when it passes from water into […]

What is the power of 10 when 75 200 is written in scientific notation? The correct answer is: 4. Explanation: In scientific notation, we place the decimal behind the first non-zero digit in the number. How do you calculate binary numbers? To convert integer to binary, start with the integer in question and divide it […]

Who named all the planets? All of the planets, except for Earth, were named after Greek and Roman gods and godesses. Jupiter, Saturn, Mars, Venus and Mercury were given their names thousands of years ago. The other planets were not discovered until much later, after telescopes were invented. What is the only planet not named […]

How do you find quantum number L? The secondary quantum number, l, divides the shells up into smaller groups of subshells called orbitals. The value of n determines the possible values for l. For any given shell the number of subshells can be found by l = n -1. This means that for n = […]
