Explanation
There are three main branches of science: physical science, Earth science and life science. Let's talk about each branch and the areas of study within each branch. Physical science is the study of inanimate natural objects and the laws that govern them.
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
2.5 M x V1 = 1.0 M x .250 L
<span>V1 = 0.10 L or 100 mL of the 2.5 M HCl solution is needed
Hope this helps.</span>
Answer:
1) The reaction rate is double with respect to that reactant
Explanation:
Hello,
By considering the rate law:

If we double the reactant A concentration, by definition, the rate will be doubled as well since the
power is one (order 1), this could be proved just by checking it out in the rate law.
Best regards.
Answer:
B. Aromatic
Explanation:
Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.
For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
Answer:Low temperatures
Explanation:
∆G= ∆H-T∆S
If ∆H is negative (exothermic reaction), then in order to maintain ∆G<0 which is the condition for spontaneity; T must decrease. This is because, decrease in T will keep the difference of ∆H and T∆S at a negative value in order to satisfy the above stated condition for spontaneity.
