Suppose you placed a tube containing 80% sucrose solution into a beaker of 40% sucrose solution. would the tube gain weight or lose weight?

gain, you add anything to the beaker there's going to be a gain in weight since there's more stuff there

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
