The american physical chemist gilbert newton lewis (1875-1946) proposed a unit of time called a jiffy. according to lewis, 1 jiffy is the time it takes light to travel 1 cm. (c= 2.998 x 10^8 m/s)

a) if you perform a task in a jiffy, how long does it take in seconds?

b) how many jiffys are in one minute?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
