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:
- Weigh and fold the filter paper.
- Place the filter paper in the funnel, then place the funnel in the Erlenmeyer flask.
- Allow the solid/liquid mixture to drain through the filter.
- Use water to rinse the filter paper containing the mixture.
- Weigh the dried filter paper and copper.
The SI unit for temperature is Kelvin.
D. All of the above. Developing medicine, analyzing compounds and producing new product such as plastic all have to deal with chemistry.
I would say A and D. A is right for sure, as for D, I'm not so sure. Hope this helps!
