Answer:
atoms bond to attain neutral configuration or to get noble gas configuration.
Explanation:
atoms always want to be stable by attaining noble gas configuration.
they do so by forming bonds. they also bond to each other to make their outer electrons stable that is if the atom has an excessive electron than its neutral configuration it can bond to another atom that has one less electron than its neutral configuration by ionic bond.

Answer:
17.2mL are needed
Explanation:
<em>The pH curve for titration of 50.0 mL of a 0.100 M solution of hydrochloric acid</em>
<em />
A strong acid as HCl reacts with a strong base as NaOH producing water and a salt. The chemical equation is:
HCl + NaOH → H₂O + NaCl
<em>Where 1 mole of HCl reacts per mole of NaOH</em>
<em />
To solve this question we must find the moles of HCl added = Moles NaOH you must add to reach the equivalence point. With these moles and the molar concentration we can find the volume that would be needed as follows:
<em>Moles HCl:</em>
50.0mL = 0.0500L * (0.100moles / L) = 0.00500 moles HCl = Moles NaOH
<em>Volume NaOH:</em>
0.00500 moles NaOH * (1L / 0.290moles) = 0.0172L NaOH =
<h3>17.2mL are needed</h3>
