You have 25.0mL HCl of unknown concentration. It takes 12.5 mL of 0.2 M NaOH to neutralize the acid. Determine the concentration

Ugo [173]

Answer:

1) The concentration of HCl = 0.1 M.

2) The table that can be used to organize the information correctly is C.

Explanation:

1) The concentration of HCl:

We know that the no. of millimoles of the acid is equal to the no. of millimoles of the base at the neutralization point.

which means that: (MV)HCl = (MV)NaOH,

M of HCl = ??? M, V of HCl = 25.0 mL.

M of NaOH = 0.2 M, V of NaOH = 12.5 mL.

∴ M of HCl = (MV)NaOH/V of HCl = (0.2 M)(12.5 mL)/(25.0 mL) = 0.1 M.

2) The table that can be used to organize the information correctly is C

Table A and B are the same and reported volume of HCl and NaOH is wrong.

Table C is right, contain the correct volumes and concentration of NaOH and missed the concentration of HCl which is 0.1 M.

Table D reported the volume and the concentration of HCl wrongly and also the concentration of NaOH. The data reported of HCl and NaOH is reversed.

CAN SOMEONE HELP ME WITH THESE QUESTIONS I WILL GIVE ALL MY POINTS 5 STARS AND THANKS AND BRAINLY ALL I ASK IS WHENN YOU ANSWER

ira [324]

1. The bird has to adjust where it doves in for the fish because the light is refracted by the water, making it look like the fish is in a different position than it is.

2. The clock is reflected in the mirror, which sends each part of the image straight back.

4. Your first part is correct. The second part: The plant would look dark brown or black and red light. Red light has no green wavelengths to reflect, and the red light would be absorbed by the leaf, making it appear almost black.

LMK if you have questions.
