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.

How many moles of NH3 can be produced from 12.0 mol of H2 and excess N2? Express your answer numerically in moles. View Availabl
VladimirAG [237]

Answer:

A) 8.00 mol NH₃

B) 137 g NH₃

C) 2.30 g H₂

D) 1.53 x 10²⁰ molecules NH₃

Explanation:

Let us consider the balanced equation:

N₂(g) + 3 H₂(g) ⇄ 2 NH₃(g)

Part A

3 moles of H₂ form 2 moles of NH₃. So, for 12.0 moles of H₂:

12.0molH_{2}.\frac{2molNH_{3}}{3molH_{2}} =8.00molNH_{3}

Part B:

1 mole of N₂ forms 2 moles of NH₃. And each mole of NH₃ has a mass of 17.0 g (molar mass). So, for 4.04 moles of N₂:

4.04molN_{2}.\frac{2molNH_{3}}{1molN_{2}} .\frac{17.0gNH_{3}}{1molNH_{3}} =137gNH_{3}

Part C:

According to the <em>balanced equation</em> 6.00 g of H₂ form 34.0 g of NH₃. So, for 13.02g of NH₃:

13.02gNH_{3}.\frac{6.00gH_{2}}{34.0gNH_{3}} =2.30gH_{2}

Part D:

6.00 g of H₂ form 2 moles of NH₃. An each mole of NH₃ has 6.02 x 10²³ molecules of NH₃ (Avogadro number). So, for 7.62×10⁻⁴ g of H₂:

7.62 \times 10^{-4} gH_{2}.\frac{2molNH_{3}}{6.00gH_{2}} .\frac{6.02\times 10^{23}moleculesNH_{3}  }{1molNH_{3}}=1.53\times10^{20}moleculesNH_{3}

Brenda rode a skateboard 95 meters west. It took her 20 seconds. What was
Artemon [7]

Answer:

D. 4.75 m/s west

Explanation:

You can immediately get the answer once you know the formula for<em> velocity.</em>

  • The formula for velocity is: Velocity (V) = \frac{distance (d)}{time (t)}

The distance is 95 meters while the time is 20 seconds. All you have to do is to divide <u>95 meters by 20 seconds</u>.

Let's solve:

  • V = \frac{d}{t}
  • V = \frac{95 meters}{20 seconds}
  • V = 4.75 meters per second

Since Brenda is going west with her her skateboard, then you have to add <em>west </em>as her direction.

Brenda's velocity is 4.75 m/s west.

A large weather balloon filled with helium has a volume of 7.00 x 102 L at STP. Which expression should be used to find the mass
balandron [24]

Answer:

mass of Helium = mole of Helium x Molarmass of Helium

Explanation:

Mole of Helium = volume of Helium/ 22.4dm^3/mol

                          = 7.00 x 10^2/22.4

                          = 31.25mol

Mass of Helium = mole of Helium x Molarmass of Helium

                           = 31.25mol x 4g/mol

                           = 125g
