HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)

A student was given the task of titrating a 20.mL sample of 0.10MHCl(aq) with 0.10MNaOH(aq) . The HCl(aq) was placed in an Erlenmeyer flask. An equation for the reaction that occurs during the titration is given above.

(b) The equation above is not written in net ionic form. Write the correct net ionic equation for the reaction.

The study of chemicals and bonds is called chemistry.

The correct answer is as follows:-

The Net ionic equation is as follows:-

H^+(aq) + OH^-(aq) ---- H_2O(l)

What is titration?Titration is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte. A reagent, termed the titrant or titrator, is prepared as a standard solution of known concentration and volume.

The Chemical equation mentioned in the equation is as follows:-

HCl(aq)+ NaOH(aq) ---- NaCl(aq) + H_2O(l)

After breaking down into the ions the Ionic equation is:-

H^+(aq) + Cl^-(aq) + Na^+(aq) + OH^-(aq) ---- H_2O(l) + Na^+(aq) + Cl^- (aq)

Net ionic equation:

H^+(aq) + OH^-(aq) ---- H_2O(l)

The Cl⁻(aq) and Na⁺ (aq) are spectator ions that are why these are not written in the net ionic equation. The water can not be split into ions because it is present in liquid form. What are Spectator ions? These ions are the same on both sides of a chemical reaction. These ions are canceled out. Their presence can not affect the equilibrium of reaction that's why these ions are omitted in the net ionic equation.

Hence, the correct answer is mentioned above.

Net ionic equation:

H⁺(aq) + OH⁻(aq) → H₂O(l)

Explanation:

Chemical equation:

HCl(aq)+ NaOH(aq) → NaCl(aq) + H₂O(l)

Ionic equation:

H⁺(aq) + Cl⁻(aq) + Na⁺(aq) + OH⁻(aq) → H₂O(l) + Na⁺(aq) + Cl⁻ (aq)

Net ionic equation:

H⁺(aq) + OH⁻(aq) → H₂O(l)

The Cl⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.

$\frac{239}{94}pu+\frac{1}{0}n ====> \frac{y}{z}x+\frac{134}{54}xe+3\frac{1}{0}$

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137 subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54 subtract 54 from both sides.

40 = z

answer

$\frac{103}{40}x=\frac{103}{40}zr$
