Filtration

Explanation:

is a process by which impurities or particles are removed from a fluid, either a liquid or a gas. The liquid, or feed, is poured over a filter, which catches particles and allows filtered liquid, or filtrate, to move through it.

I'm in middle school, and I answered an basic question for you. Come on man, all you have to do is look up the definition.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
