exis [7]3 years ago
3 0

Answer:

Hal is wrong because the teacher can instruct the student, but no make all the choices in a lab.Students must always wear ppe (personal protection equipment) , use proper lab protocol, and conduct themselves in a responsible manner. It is NOT the work of a teacher to ensure lab safety, but in fact the responsibility of said students.

Calculate the ph of a mixture that contains 0.18 m of hno3 and 0.24 m of hbro
Kobotan [32]
HNO3 is a strong acid while HBrO is weak acid.
Therefore we ignore the presence of the weak acid such that we consider the pH of the strong acid.
Therefore; since pH= - log (H+)
Hence pH= -log 0.18
                = 0.745
Thus the pH of the mixture is 0.745

How many mL of a 0.300 M AgNO3 solution will it take to make 500 mL of a 0.100 M AgNO3 solution?
sergeinik [125]
The answer is 166 mL. You use the formula V1*M1=V2*M2. For what you're given you rearrange the formula to V1=M2*V2/M1 so V1= (0.500 mL)(0.100 M AgNO3)/(0.300 M AgNO3) = 166 mL

All of these conditions can cause protein denaturation, except:
Free_Kalibri [48]

Answer:

The correct option is: an increase in body temperature due to high fever

Explanation:

Denaturation of protein is a process by which the protein unfolds i.e. loses it's quaternary, tertiary, and the secondary structure when exposed to <u>high temperature (above 41°C)</u>, <u>change in pH</u> or<u> chemical denaturants</u>. Denaturation of proteins leads to loss of activity.

The enzymes <u>pancreatic proteases</u> breaks down proteins by hydrolysis, thus leading to the denaturation of protein.

<u>Since, generally fever does not increase the body temperature above 41°C. Therefore, it doesn't lead to denaturation of protein.</u>
