In the simulation, were you able to use noninteger numbers (like ½ or 0.43) for the coefficients in a balanced equation? why do you think this is?

By standard convention, decimals and fractions are avoided or rather do away with when balancing chemical equations.

We do not have decimals when balancing equations, because we are balancing atoms and molecules. You can't cut an atom or a molecule in half after all, so you must use whole numbers.

By doing away with decimals and fractions, mole relationships between reactants and products are simply presented.

It is much more understandable and presentable to say; "2 moles of Hydrogen gas reacts with 1 mole of oxygen gas to form2moles of water molecule"

Rather than; "1 moles of Hydrogen gas reacts with 1/2 mole of oxygen gas to form 1 moles of water molecule"

it's filtration, but this is an assumption so my apologies if i got this

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.
