In an experiment, marble chips reacted with dilute hydrochloric acid and carbon dioxide gas was given off. The experiment was done twice, once using small marble chips and again with large marble chips.
Look at the graph. Was the total mass of marble chips the same each time?

no

Explanation:

Small marble chips reacts faster

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
