Describe what happens when a. piece of potassium is dropped into a trough of water coloured with red litmus. Pls help, it's urgent!!!

The potassium floats, fizzes as it makes hydrogen, the hydrogen gas is so hot it self combusts and burns with a lilac flame. The red litmus will show little blue trails until everything mixes and it turns evenly blue. If the piece of potassium is big enough it may also explode, spraying blobs of molten metal for several meters.

indium, and thallium have three electrons i think

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
