Answer:
Magnesium is in Group 2 (sometimes called Group II or 2A). Since it is in Group 2 it will have 2 valence electrons. When you draw the Lewis structure for Magnesium you'll put two "dots" or valance electrons around the element symbol (Mg).GOOD LESSONS ♡

2.9 is the ph of a buffer solution made by adding 0. 010 mole of solid naf to 50. ml of 0. 40 m HF.
pH
The hydrogen ion concentration in water is expressed by pH. Specific to aqueous solutions, pH is the negative logarithm of the hydrogen ion (H+) concentration (mol/L):
pH equals -log(H+)10
The phrase refers to a solution's basicity or acidity in a range of 0 to 14, with pH 7 representing neutrality. The pH decreases and acidity rise as the concentration of H+ ions in the solution.
Since pH is a logarithmic function, a pH shift of one unit (for example, from 7 to 6) corresponds to a 10x change in the concentration of H+ in the solution. However, hydrogen ion activity, not concentration, is what is actually measured.
