The presence of salt that is sodium chloride cannot be tested at once. Two different tests are performed to show the presence of both sodium and chloride.
To test for the chloride ion:
Add few drops of aqueous solution of silver nitrate to aqueous solution of sodium chloride, white precipitate is seen which cannot dissolve in cold water and dilute nitric acid. This precipitate formed is soluble in solution of ammonium hydroxide to give a colorless diamine silver chloride solution.
To test for the sodium ion: Use a flame test.
Dip a wire of platinum in concentrated hydrochloric solution and hold it in the flame of the Bunsen burner until the flame no longer changes its color. Again dip the wire in hydrochloric solution and rub some sodium chloride on the wire and put it again in the burner, an intense yellow to orange color forms that shows the presence of sodium ion.
If the substance passes both the tests in the given way then it is salt (sodium chloride)
<span>superposition.. its literally word for word "secondary layers are placed on top of the first layers which are on the bottom"</span>
the answer is cannabinoids
1. Photosynthesis occurs in the Chloroplast, which contain a chlorophyll whereas Cellular Respiration takes place in the double-membrane organelle called the mitochondrion.
2. PHOTOSYNTHESIS:
<em>6CO2 + 6H2O → C6H12O6 + 6O2.</em>
The reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.
CELLULAR RESPIRATION :
<em>C6H12O6 + 6O2 → 6CO2 + 6H2O.</em>
<em>T</em><em>he equation for cellular respiration is the direct opposite of </em><em>photosynthesis</em><em>.</em><em> </em>
<em>3.</em><em> </em>Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Answer:
I think its 1 cells all come from pre existing cells. have a nice day hope this isnt too late :)
Explanation:
im taking the test too
