Answer: The acceleration is 50.
Explanation: You can actually re-arrange the formula F = ma to F/m = a. 250/50 = 50.
Answer:
Paraffin wax's general chemical formula is CnH2n+2, according to ChemistryViews, with n being a varying number of carbon atoms. Although the chemical composition of the wax is always carbon and hydrogen, the actual number of atoms will vary based on the exact origin of the wax.
Answer:
Take 46.9 ml of the 12 M solution using a graduated cylinder and pour the liquid in a 250-ml volumetric flask. Add water until the mark.
Explanation:
To prepare this solution, you have to take a volume of the 12 M HCl solution and add water to 250 ml. What volume should you take?
The number of moles of HCl present in the volume you take from the concentrated solution will be the same as the number of moles in the final solution since you are only adding water. Then:
number of moles of HCl in the taken volume = number of moles in the final solution.
number of moles of HCl = concentration (in molarity) * volume
Then:
Ci * Vi = Cf * Vf
Where
Ci = the concentration of the solution from which you take the volume to prepare the more diluted solution.
Vi = the volume of the concentrated solution you have to take.
Cf = Concentration of the final solution
Vf = volume of the final solution
Replacing with the data:
12.0 M * Vi = 250.00 ml * 2.25M
<u>Vi = 46.9 ml </u>
