The charge on an electron is ~
" - " symbol is used to show that its negative.
Answer:
To predict the number of shearing electron between the two atoms (ionic bond) the concept of electronegativity is used.In the other words the ability of atoms to attracts the electron is known as electronegativity of the atom.
If the electronegativity between two atoms is greater than 1.7 then these types of bond is known as ionic bond.These types of bond will show ionic character.
Answer:
Add 10 mL of ethanol into a 100 mL volumetric flask. Final volume of diluted ethanol solution is 100 mL.
Explanation:
We need to use a flask of 100 mL to make a 10 times dilution of the 10 mL of ethanol that we have. To prepare this solution we have to measure with a pipet 10 mL of ethanol and place it into volumetric flask of 100 mL. Then we add destiled water to complete the volume of the final ethanol solution.
Then the final volume of the diluted solution of ethanol will be 100 mL.
Answer: Thus pOH has value of 8.19
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration.
Putting in the values:
Thus pOH has value of 8.19
