Answer:

The chemical equation for step 1 is 2 NO2(g) → NO(g) + NO3(g), and the rate law is rate = k[NO2]^2

Explanation:

We know that the rate determining step is the slowest step in a sequence of non elementary reactions.

As we can see, the first reaction is slow so it is the rate determining step. From here we obtain the rate equation.

Also, the specie NO3 is absent in the overall reaction equation indicating that it is merely an intermediate produced in step 1 and used up in step 2.

The chemical equation for step 1 is [tex]2 NO_2(g) \rightarrow NO(g) + NO_3(g)[/tex], and the rate law is [tex]rate = k[NO_2]^{2}[/tex].

The rate -determining step is the slowest step in a sequence of non -elementary reactions.  The first reaction is slow so it is the rate determining step. From here we obtain the rate law.

Also, the specie [tex]NO_3[/tex]  is absent in the overall reaction equation indicating that it is merely an intermediate produced in step 1 and used up in step 2.

So, the chemical equation for step 1 is [tex]2 NO_2(g) \rightarrow NO(g) + NO_3(g)[/tex], and the rate law is [tex]rate = k[NO_2]^{2}[/tex].

Answer:

Explanation:

The dilution factor : 100

The dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution

From equation of dilution :

M₁V₁=M₂V₂

[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]

Volume of aliquot = 0.1 ml

Volume of diluent = 9.9 ml

So final volume :

[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]

The dilution factor (DF) :

[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]

Explanation:

Answer:

28.8g

Explanation:

I think your chemical equation should be:

2KClO3 → 2KCl +3O2

Number of moles of KClO3

[tex] = \frac{mass}{molar \: mass} [/tex]

[tex] = \frac{69}{39 + 35.5 + 3(16)} [/tex]

[tex] = 0.6mol[/tex]

From the equation,

2 mol of KClO3 : 3 mol of 02

So...

0.6 mol of KClO3 : 0.9 mol of O2

Number of moles of O2= 0.9mol

So the mass of O2 formed = number of moles× molar mass

= 0.9 × 2(16)

= 28.8g

If 69 gram of KClO₃ decomposes then 27.036 grams of oxygen will form.

Stoichiometry helps us use the balanced chemical equation to measure the quantitative relationship and it is to calculate the amount of product and reactants that are given in a reaction.

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The given balanced equation is

2KClO₃ → 2KCl + 3O₂

According to Stoichiometry, x gram of oxygen will form

= [tex]69\ \text{g of}\ KClO_{3} \times \frac{1\ \text{mol}\ KClO_{3}}{122.55\ g\ KClO_{3}} \times \frac{3\ \text{mol}\ O_2}{2\ \text{mol}\ KClO_{3}} \times \frac{32\ g\ O_2}{1\ \text{mol}\ O_2}[/tex]

= 27.036 grams of Oxygen

Thus from the above conclusion we can say that If 69 gram of KClO₃ decomposes then 27.036 grams of oxygen will form.

Answer:

86

Explanation:

The reaction that takes place is:

First we convert moles of ethanol to moles of water:

Then we convert moles of water to grams of water, using its molar mass:

So 84.6 grams of water will be produced.

The mass of water, H₂O produced when 1.6 moles of ethanol, C₂H₅OH are completely burned is 86.4 g

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

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

From the balanced equation above,

1 mole of C₂H₅OH reacted to produce 3 moles of H₂O.

Therefore,

1.6 moles of C₂H₅OH will react to produce = 1.6 × 3 = 4.8 moles of H₂O.

Mole of H₂O = 4.8 moles

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass = mole × molar mass

Mass of H₂O = 4.8 × 18

Thus, the mass of water obtained from the reaction is 86.4 g

Answer:

Concept: Chemical Analysis

Answer:

0.75 mol

Explanation:

Given data:

Number of moles of Na = 0.75 mol

Mass of water = 500 g

Moles of hydrogen gas produced = ?

Solution:

Chemical equation:

Na + H₂O   →      NaO + H₂

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 500 g/ 18 g/mol

Number of moles = 27.8 mol

now we will compare the moles of hydrogen gas with both reactant.

                   Na         :          H₂

                    1            :          1

                  0.75       :         0.75

                 H₂O        :          H₂

                   1            :           1

               27.8          :         27.8

sodium will act as limiting reactant it produced small number of moles of hydrogen gas as compared to water.

Thus, number of moles of hydrogen gas are 0.75 mol.
