A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).E - 3. Organic carbon is converted to fossil fuels.H - 4. Carbon dioxide is converted to carbonates.F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).
There can be three mole ratios that can be written involving three substances.It depends on the constant of your reactant to your product. It also depends on the asked mole ratio. But the maximum would be 3 mole ratios because you have 3 substances in your reaction.
Answer:
Is pink in base solution, it provides a visual signal that a solution has changed from acid to a base, is colorless in acid solution.
Explanation:
As all the indicator, phenolphtalein has the property that turns pink when the solution that you have reaches a value of a pH of 9 or above. From 0 to 8 in a pH scale, is colorless. This point in which an indicator changes is it called equivalence point.
They have began to grow apart, as their lives are changing and as they are growing older, they are growing further apart.
I would say the answer is B - Differentiating
The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).
The chemical equation for this precipitation reaction is as following:
AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)
- Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
- If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.
