The ml of 12.0 M HCL needed to prepare 905.0 ml of 1.00m hcl is calculated using M1V1 =M2V2 formula
M1= 12.0 M
V1=?
M2= 905.0 ml
V2 = 1.00M
V1 is therefore = M2V2/M1
=905 x 1.00/12.0 = 75.42 ml
Answer:
Yes, acetic acid could be used, but it would not be as effective as acetyl chloride or acetic anhydride. ... However, the acetic anhydride would still be reacting with an alcohol, so nothing changes in that respect. Also, the reaction would need to be done in basic solution.
The correct answer is A because pollution is a leading factor of pollution.
The accumulation of toxins in the pond from the poor air quality will lead to a change in the acidity of the pond.
I hope I helped! :)
Mg = 24.3 g/mol
23.5 g / 24.3 g/mol = 0.97 mol Mg
