The given reaction is the type of Decomposition reaction. A decomposition reaction occurs when one reactant splits into many products.

What does a reaction's breakdown entail?

Chemistry reaction reactions of decomposition. Decomposition reactions occur when complex chemical entities split apart into smaller components. Decomposition reactions often demand energy input.

What are the names for decomposition reactions?

Decomposition reactions are those that divide or break the compounds into two simpler products. Because two or more reactants are combined to create a single product in a combination reaction, they are known as the reverse of combination reactions.

The exothermic nature of a decomposition reaction is why?

It entails the severing of ties. Energy is necessary to dismantle the bonding between atoms. Decomposition advances when energy in the form of heat or electricity is provided. As the bond is broken during this reaction, energy is given to them, making them endothermic processes.

P5-F2 + Ar --> ArF3
P5a- How many moles of F2 (Fluorine) are needed to produce 9 mole of ArF3 (Argon trifluoride)?
P5b- How many moles of Argon (Ar) are consumed in a reaction that consumes 5 moles of F2 (fluorine)?


I need the answers for the p5 part please help

Answers

Answer:

5a. 13.5 moles of F₂

5b. 3.33 moles of Ar.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3F₂ + 2Ar —> 2ArF₃

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar to produce 2 moles of ArF₃.

5a. Determination of the number of mole of fluorine, F₂, needed to produce 9 moles of ArF₃.

From the balanced equation above,

3 moles of F₂ reacted to produce 2 moles of ArF₃.

Therefore, Xmol of F₂ will react to produce 9 moles of ArF₃ i.e

Xmol of F₂ = (3 × 9)/2

Xmol of F₂ = 13.5 moles

Thus, 13.5 moles of F₂ is needed.

5b. Determination of the number of mole of Ar needed to react with 5 moles F₂.

From the balanced equation above,

3 moles of F₂ reacted with 2 moles of Ar.

Therefore, 5 moles of F₂ will react with = (5 × 2)/3 = 3.33 moles of Ar.

Thus, 3.33 moles of Ar was consumed.

what is the mass in grams of 1.204x10^24 molecules of hydrogen gas (H2) ?

Answers

Answer:

4.03 g

Explanation:

The mass in grams of the hydrogen gas is 4.0 g

Stoichiometry

From the question,

We are to determine the mass in grams of the hydrogen gas.

First, we will determine the number of moles of hydrogen gas present.

Using the formula,

[tex]Number\ of\ moles =\frac{Number\ of \ molecules}{Avogadro's\ constant}[/tex]

From the given information,

Number of hydrogen molecules = 1.204 × 10²⁴ molecules

Thus,

Number of moles of hydrogen gas present = [tex]\frac{1.204 \times 10^{24} }{6.02 \times 10^{23} }[/tex]

Number of moles of hydrogen gas present = 2 moles

Now, for the mass of the hydrogen gas

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of hydrogen gas = 2.016 g/mol

Then,

Mass of the hydrogen gas = 2 × 2.016

Mass of the hydrogen gas = 4.032 g

Mass of the hydrogen gas ≅ 4.0 g

Hence, the mass in grams of the hydrogen gas is 4.0 g

What is the final temperature of both substances at thermal equilibrium?

Answers

Answer:

The final temperature of both substances at thermal equilibrium is 17.3°C

Explanation:

To calculate the final temperature of both substances at thermal equilibrium -:

First , we calculate the heat of A1  cube as follows -

            q= mSΔT

(where q = heat of the cube , m = mass of cube , S= specific heat of cube  {0.902j/g°C}, T = Temperature )

Putting the values given in the question ,

        [tex]q= 32.5g\times0.902\j/g[/tex]°[tex]C[/tex][tex]\times(T_f-45.8[/tex]°[tex]C)[/tex]

            [tex]29.315\times(T_f-45.8)J[/tex]

Now , calculate the heat of water -

         q=mSΔT

Putting values from the question ,

           [tex]q=105.3g\times4.18j/g[/tex]°[tex]C[/tex][tex]\times (T_f-15.4[/tex]°[tex]C)[/tex]

              =[tex]440.154\times(T_f-15.4)J[/tex]

          Now ,

Heat lost by water A1= Heat gained by water [negative sign about heat lost]

         [tex]-29.315\times(T_f-45.8)J[/tex] [tex]=440.154\times(T_f-15.4)J[/tex]

            [tex]\frac{-(T_f-45.8)J}{T_f-15.4)J} =\frac{440.154}{29.315}=15.0[/tex]

      [tex]-T_f+45.8[/tex]°[tex]C=15T_f-231.2[/tex]°[tex]C[/tex]

       [tex](45.8+231.2)[/tex]°[tex]C[/tex]=[tex]16T_f[/tex]

        [tex]16T_f=277.03[/tex]°[tex]C[/tex]

       [tex]T_f=\frac{277.03}{16}[/tex] = 17.3°C

Therefore , the final temperature of both substances at thermal equilibrium is 17.3°C
