Answer:
If aluminum is the limiting reactant, <em>NONE </em>of it will still be visible after the reaction completes.
If CuCl2 is the limiting reactant, <em>SOME</em> of the aluminum will still be visible.
Explanation:
- Any chemical reaction, if the reactants are not in equimolar ratios, contains limiting reactant and leftover reactant.
- The limiting reactant in a chemical reaction is the reactant that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
- The leftover reactant is the reactant that is in excess and not consumed completely and some of it remains in the reaction mixture.
So,
If aluminum is the limiting reactant, <em>NONE </em>of it will still be visible after the reaction completes.
and,
If CuCl2 is the limiting reactant, <em>SOME</em> of the aluminum will still be visible.
Answer:
Benzoic acid
Explanation:
The strength of an acid is principally a measure of its dissociative capabilities in aqueous solutions. While strong acids dissociate completely in solution, weak acids dissociates only partially.
The relative strength of an acid can be obtained from its pKa value. The pKa value is the negative logarithm of the concentration of the Ka value.
Stronger acids have a pKa value usually negative. This is a pointer to the fact that the lower the pKa value, the stronger the strength of the acid in question.
Relatively therefore, Benzoic acid is stronger than acetic acid because it has a lesser value for pKa
No its not it can be different.
Answer:
This is the typical route of alcohol metabolism, where in the liver it is first transformed to acetaldehyde and then to acetate.
Explanation:
Ethanol is not digested but absorbed and follows its metabolic pathway in the liver, producing in the first instance acetaldehyde, which is the main substance that causes the hangover and then this compound is transformed into the final product, which is acetate Later acetate is metabolized to Acetyl-CoA. The enzyme responsible for the metabolism of ethanol is alcohol dehydrogenase in the liver, and for the cytochrome P-450 dependent system and for catalase in the liver.
<em>Answer:</em>
- Such a alkane has only one ring that is cyclooctane.
<em>Explanation:</em>
- The general formula of alkane is CnH2n+2. Such general formula is applicable for only open chain alkane.
- When alkane form ring, then this formula does not remain valid.
- The general formula of Cycloalkane is CnH2n.
As in this case, there are 8-carbon and 16-hydrogen that is according to above cycloalkane formula.
