Answer:
The chlorine atom (or atoms) is covalently bonded by a shared pair of electrons to the other element.
Explanation:
1. 0+15+30+45+60=150/5=30 s
0+10+16+22+27=75/5=15 cm^3
then, 15/30= 0.5 cm^3/s(average rate of rxn)
2. 0+15+30+45+60+75+90+105+120=540/9=60 s
0+10+16+22+27+31.50+36+39.5+42=224/9=24.89cm^3
then, 24.89/60=0.414cm^3/s (avrg rate of rxn)
3. overall rxn add all the time divide by 12 and the volume add them too and divide by 12. after take average volume divide by the average time to get the average rate of overall rxn
4. 16/30= 0.533cm^3/s
5. 39.5/105= 0.37cm^3/s
The correct answers from the choices are:
a. Reduce inflammation locally
b. Antagonize H1 receptors
c. May be administered orally
<span>d. Are systemically distributed
</span><span>Antihistamines are drugs that are H1 antagonists or blockers, may be administered orally, are distributed systemically, and do not directly reduce nasal congestion.</span>
Answer:
1.33 M
Explanation:
We'll begin by writing out the data obtained from the question. This includes the following:
Volume of the stock solution (V1) = 0.5L
Molarity of the stock solution (M1) = 4M
Volume of diluted solution (V2) = 1.5L
Molarity of the diluted solution (M2) =.?
With the application of the dilution formula, the molarity of the diluted solution can be obtained as follow:
M1V1 = M2V2
4 x 0.5 = M2 x 1.5
Divide both side by 1.5
M2 = (4 x 0.5) / 1.5
M2 = 1.33 M
Therefore the molarity of the diluted solution is 1.33 M
