The percent composition of potassium chloride, KCl, can be calculated from the atomic weights of potassium and chlorine and the formula weight of KCl.
Formula weight of KCl: 39.10 g + 35.45 g = 74.55 g
Percent potassium: 39.10 g K
74.55 g KCl X 100% = 52.45% potassium
Percent chlorine: 35.45 g Cl
74.55 g KCl X 100% = 47.55% chlorine
process by which one separates compounds from one another by passing a mixture through column that retains some compounds longer than others.
Answer:
Photosynthesis is the process through which autotrophs are bale to produce their own food. The Process is named so because photo means sun's light and synthesis means creating. It involves the Plants or other autotrophs absorbing the sun's light and also carbon dioxide released into the atmosphere by respiration. As a result of Photosynthesis, we obtain what is known as oxygen. This is, in fact, the biproduct of the process. Mainly, Photosynthesis occurs due to the presence of Chlorophyll which give leaves their green colour.
key terms:
Authotrops: Those who have the ability to produce their own food.
Biproduct: The extra result of a scientific equation.
Chlorophyll: a green pigment, present in all green plants and in cyanobacteria, etc.
Hope this helped pls brainliest me if you can <3
You can find it by adding the standard atomic masses of the constituent atoms.
