Answer:
Electron shells surrounding the nucleus.
Answer:
0.005 M
Explanation:
Given data:
volume of sample solution ( volume of D ) = 5.0 mL
volume of added stock solution ( V1 ) = 5.0 mL
concentration of added stock solution ( N1 ) = 0.02 M
Total volume of concentration ( V2 )= 10 mL = ( 5.0 mL + 5.0mL)
concentration of Total volume of sample ( C2 ) = 0.01
N2 = ( N1V1 ) / V2
= ( 0.02 * 5 ) / 10 = 0.01 m
absorbance of sample solution ( A1 ) = 0.10
absorbance of additional sample solution ( A2 ) = 0.20
attached below is the remaining part of the detailed solution
I would answer this but i have to go to bed i have a reading test tommorow
Answer:
Bases (solutions with a high pH) feel slipper, have an -OH group, and are corrosive.
Answer:
The answer is 11 electron and 11 protons respectively
Explanation:
Since the sodium is in it neutral state, number of electron is the same as the number of proton, which is 11.
