Answer:
Every atom wants to get a stable state so atom combines to fill the outermost shell and become stable by either losing electrons or gaining electrons. Atom form chemical bonds with over atoms when there is an electrostatic attraction between them.
Explanation:
A mixture is made from different substances that are not chemically joined. For example, powdered iron and powdered sulfur mixed together makes a mixture of iron and sulfur.
<span>Cotton balls and pine cones are similar in that they both grow on plants and they contain the seeds of that plant. However, that is where the similarities end. By sight and feel alone, cotton balls and pine cones are vastly different. Cotton balls are soft and light, while pine cones have the potential to be a little dry and pri.ckly and have a bit of heft to them.</span>

THE CORECT QUESTION
A 50.0 mL solution of 0.127 M KOH is titrated with 0.254 M HCl. Calculate the pH of the solution after the addition of each of the given amounts of HCl.
SOLUTION
Get the concentration of the HCl first using titration formula
CA X V A / CB VB = NA/ NB
Equation of reation; KOH + HCl => KCl + H2O
CA = 0.254 M
CB = 0.127
VA = 1/0.254 = 3.937
CA (after the addition) = 0.127 x 50 / 3.937
= 1.612 M
But pH = - Log[hydrogen ion]
= -log 1.612
=
