Consider the following equation:
C7H9 + 3 HNO3 → C7H6(NO2)3 + 3 H2O
Identify the product(s) for this reaction.
a. C7H6(NO2)3
b. H2O
c. HNO3 d. C7H9 and H2O
<u>e. C7H6(NO2)3 and H2O</u>
Answer:
B
Explanation:
The methyl prefix means theres a CH3 group bonded to a carbon in a hydrocarbon. This is called branching because it looks like a branched tree. This is literally cheating but you do you.
Answer:
00.001 mol/h+
Explanation:
The ph of a solution is defined as the negative iogaristhum pf the hydrogen ion concentration(in mole)ph=log(h+)poh=-log
Answer:
You see the concentration decreased ten fold, from 1 M to 0.1 M.
You can simply increase the volume by ten times.
For example
If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.
If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.
C1 = starting concentration.
C2 = final concentration.
V is for volume.
So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.
1 M x V1 = 0.1 M x 50 mL
V1 = 5 mL
So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.
