Put the list in chronological order (1–5). allow the solid/liquid mixture to drain through the filter. use water to rinse the filter paper containing the mixture. place the filter paper in the funnel, then place the funnel in the erlenmeyer flask. weigh the dried filter paper and copper. weigh and fold the filter paper.

Explanation:

Filtration is a separation technique in which solid particles suspended in liquid medium are separated by allowing the mixture through the pores of the filter paper. By this solid particles get collect on filter paper and liquid drains out from the pores of the filter paper.

The chronological order for given steps will be:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

i think its 100

i hope this !
