Answer:
B. The order in which specific traits may have evolved
Explanation:
Answer:
Functional groups
Explanation:
A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.
There are several functional groups in organic chemistry that determine the properties of organic compounds.
For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.
Answer:
1.4% salt residue
Explanation:
Mass percent can be found using the formula:
mass of solute (grams)
------------------------------------ x 100%
mass of solution (grams)
Therefore, since you have been given the weights of both the solute and solution, you can use the formula to solve for the mass percent.
3.50 g salt residue
----------------------------- = 0.014 x 100% = 1.4% salt residue
250 g salt solution
Answer:
c. remain constant.
Explanation:
The half life is defined as the time at which the reactant's concentration reduced to half.
The formula for the half life for a first order kinetic reaction is:
Where,
is the half life
k is the rate constant.
<u>As seen from the formula the half life for a first order reaction is independent of the reactant's concentration. </u>
<u>So, it will remain constant on any change of the reactant's concentration.</u>
