Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:
Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water.
or we can add H2SO4 to produce:
Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. <span />
<u><em>Buffers</em></u> <span>are solutions that resist changes in ph when moderate amounts of acids or bases are added and contain ions or molecules that react with oh- or h when these ions are introduced into solution.</span>
density of acetone in gm/cm^3 is 0.791
=28.80cm^3*0.791 g/cm63
=22.78 g
Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 100 g
volume = 20 mL
So we have

We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
