The equation for the dissociation of NaCl is  \boxed{{\text{NaCl}}\left({aq}\right)\to{\text{N}}{{\text{a}}^ + }\left({aq}\right)+{\text{C}}{{\text{l}}^ - }\left({aq}\right)}

The equation of the dissociation of {\mathbf{Fe}}{\left({{\mathbf{Cl}}{{\mathbf{O}}_{\mathbf{4}}}}\right)_{\mathbf{3}}} is \boxed{{\text{Fe}}{{\left({{\text{Cl}}{{\text{O}}_4}}\right)}_3}\left({aq}\right)\to {\text{F}}{{\text{e}}^{3+}}\left({aq}\right)+3{\text{ClO}}_4^ -\left( {aq}\right)}

Further Explanation:

The attraction between atoms, molecules or ions which results in the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding.

Ionic compounds are the compounds that are formed from the ions of the respective species. Ions are the species that are formed either due to loss or gain of electrons. A neutral atom forms cation by the loss of electrons and anion by the gain of electrons.

For example, {\text{MgC}}{{\text{l}}_2} is an ionic compound formed from one {\text{M}}{{\text{g}}^{2 + }} and two {\text{C}}{{\text{l}}^ - } ions. Its dissociation occurs as follows:

{\text{MgC}}{{\text{l}}_2}\rightleftharpoons {\text{M}}{{\text{g}}^{2+}}+{\text{2C}}{{\text{l}}^ - }

(A) NaCl is an ionic compound formed by one  {\text{N}}{{\text{a}}^ + } and one {\text{C}}{{\text{l}}^ - } ions. The reaction for  dissociation of NaCl is,

{\text{NaCl}}\to{\text{N}}{{\text{a}}^+}+{\text{C}}{{\text{l}}^ - }

(B) {\mathbf{Fe}}{\left({{\mathbf{Cl}}{{\mathbf{O}}_{\mathbf{4}}}}\right)_{\mathbf{3}}}  is an ionic compound formed by one {\text{F}}{{\text{e}}^{3 + }} and three {\text{ClO}}_4^ - ions. The reaction for dissociation of  {\mathbf{Fe}}{\left({{\mathbf{Cl}}{{\mathbf{O}}_{\mathbf{4}}}}\right)_{\mathbf{3}}} is,

{\text{Fe}}{\left({{\text{Cl}}{{\text{O}}_4}}\right)_3}\left({aq}\right)\to{\text{F}}{{\text{e}}^{3+}}\left({aq}\right)+3{\text{ClO}}_4^ -\left({aq}\right)

1. Answer;

Equation;

-NaCl(aq) → Na{+}(aq) + Cl{-}(aq)

Explanation;

-The polar property of water allows ionic compounds such as sodium chloride to dissolve in water. (sodium chloride is an ionic compound).

-Sodium chloride dissociates in water into sodium ions and chloride ions as shown by the equation. Water molecules surrounds the negatively charged chloride ions and positive sodium ions and pulls them away into solution.

2. Answer;

Equation;

Fe(ClO4)3(aq) → Fe 3+(aq) + 3ClO4 - (aq)

Explanation;

Iron (iii) perchlorate (Fe(ClO4)3 dissociates in water into iron (iii) ion and perchlorate ion. Iron (iii) ion is positively charged while the perchlorate ion is negatively charged, they are pulled apart by the polar water molecules, a process called dissociation.

Answer:

C7H16 + 11 O2 → 7 CO2 + 8 H2O

This is an oxidation-reduction (redox) reaction:

How many acetate ions are formed when three formula units of zinc acetate dissociate?
jeyben [28]
A formula unit is the same as the empirical formula of a compound or an ionic molecule. It is the lowest ratio of the atoms in the compound or ion. Zinc acetate ions dissociates into zinc ions and acetate ions. The dissociation reaction is expressed as follows:
Zn(O2CCH3)2 = Zn2+ + 2(O2CCH3)1-

We determine the amount of acetate ions produced as follows:

Moles Zn(O2CCH3)2 = (3 formula units Zn(O2CCH3)2) ( 1 mol / 6.022x10^23 formula units) = 4.98x10^-24 mol Zn(O2CCH3)2
moles (O2CCH3)1- = 4.98x10^-24 mol Zn(O2CCH3)2 ( 2 mol (O2CCH3)1- / 1 mol Zn(O2CCH3)2 ) = 9.96x10^-24 mol (O2CCH3)1-
# of acetate ions = 9.96x10^-24 mol (O2CCH3)1- ( 6.022x10^23 ions / 1 mol (O2CCH3)1-) = 6 acetate ions

Jamie is measuring the mass of one mole of carbon. She measures the mass 4 times, achieving the following measurements: 11.86 g,
azamat

This is an incomplete question, here is a complete question.

Distinguish between Accuracy and Precision Question Jamie is measuring the mass of one mole of carbon. She measures the mass 4 times, achieving the following measurements: 11.86 g, 11.87 g, 11.89 g, and 11.90 g. If the accepted value of one mole of carbon is 12.11 g, how can Jamie's measurements best be described?

Select the correct answer below:

Jamie's measurements are both precise and accurate,

Jamie's measurements are accurate but not precise.

Jamie's measurements are precise but not accurate,

Jamie's measurements are neither precise nor accurate,

Answer : The correct option is, Jamie's measurements are precise but not accurate.

Explanation :

Accuracy : It is defined as the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.

Precision : It is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

As we are given that:

The measurements are, 11.86, 11.87, 11.89 and 11.90

The accepted value is, 12.11

The average of these values =  \frac{11.86+11.87+11.89+11.90}{4}=11.88

From this we conclude that, these measurements are close to each other that means they are precise. But the accepted value are not equal to average of four values that means they are not accurate.

Hence, the correct option is, Jamie's measurements are precise but not accurate.
