Hello!
It's actually easy to add a half drop of NaOH from the buret, you'll only need to be careful.
For doing that, you'll need to first open the flow of the buret until a little drop appears, and close it before it falls to the titrating flask. Then, you'll need to rinse the tip of the buret with deionized water to make the half drop fall into the titrating flask.
Don't worry about diluting your sample with the deionized water, since you are titrating the total moles of your analyte in the solution, and those won't change with concentration.
Have a nice day!
<u>Given:</u>
Velocity of the dog, v = 5.4 m/s
Centripetal acceleration, a = 48.6 m/s2
<u>To determine:</u>
Radius of the path
<u>Explanation:</u>
The centripetal acceleration is related to the velocity and radius as:
a = v²/r
r = v²/a = (5.4 m/s)²/48.6 m/s2 = 0.6 m
Ans: Radius of the path is 0.6 m
Answer:
25
Explanation:
25 may or may not be right im not the best with measuring math stuff but i did
50x2 which is 100 i then divided that by 2 for the 50 again which was a little pointless then i just divided 50 by 2 which we all know to be 25
hope this helped if not really really sorry
The balanced chemical reaction will be:
H2 + Cl2 = 2HCl
We are given the amount of reactants and since chlorine is in excess we can say that all of the hydrogen supplied will be in complete reaction. This will be our starting point.
0.8 g H2 (1 mol H2 / 2.02 gH2) (2 mol HCl/1mol H2) ( 36.46 g HCl/1mol HCl) = 28.88 g HCl
Thus, the answer is 28.88g H2O.
