How many moles of carbon dioxide are formed when 32 moles of oxygen gas are consumed?

CH4(g) + 2O2(g) --> CO2(g) + 2H2O(g)

The classification of the above given compounds would be listed below as follows:

a.) Cu2CrO4 = ionic

b. Ba(NO3)2 = ionic

c. Cl2O = ionic

d. BrF5= covalent

An ionic compound are those chemical substances that are made up of both positively charged ions called cations and negatively charged ions called anions.

A covalent compound is defined as the type of chemical compound that is formed when two nonmetals react with each other. This is seen in the chemical compound BrF5 where bromine and fluorine which are both nonmetals react with each other.

Answer:

4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

Explanation:

The given reaction equation is expressed as:

        C₃H₃N   +    O₂    →   C  +   H₂O    +     N₂

The problem here entails balancing of the chemical reaction.

 So;

assign letters a,b,c,d and e as coefficients that will balance the expression:

            aC₃H₃N   +    bO₂    →   cC  +   dH₂O    +     eN₂

Conserving C :  3a  = c

                   H :   3a  = 2d

                   N :    a = 2e

                   O:    2b  = d

let a  = 1, c  = 3, e  = [tex]\frac{1}{2}[/tex]  , d  = [tex]\frac{3}{2}[/tex]  , b  =  [tex]\frac{3}{4}[/tex]

    Multiply through by 4;

          a  = 4, b  = 3, c  = 12 , d  = 6 and e  = 2

                4C₃H₃N   +    3O₂    →   12C  +   6H₂O    +     2N₂

Explanation:

The mass of oxygen gas : = 61.98 g

Given

Reaction

Zn(ClO3)2 → ZnCl2 + O2

The mass of zinc chlorate was 150 grams

Required

The mass of oxygen gas

Solution

Balanced equation :

Zn(ClO₃)₂ → ZnCl₂ + 3O₂

mol of Zn(ClO₃)₂ :

= mass : MW

= 150 : 232.29 g/mol

= 0.6457

From equation, mol ratio of Zn(ClO₃)₂ → ZnCl₂ : O₂ = 1 : 3, so mol O₂ :

= 3/1 x mol  Zn(ClO₃)₂

= 3/1 x 0.6457

= 1.937

Mass of  O₂ :

= mol x MW

= 1.93  x 31.998 g/mol

= 61.98 g

Or we can use equation :

= (150 x 3 x 31.998) : (232.29 x 1) grams

= 14399.1 : 232.29

= 61.98 g

The number of moles of Zn(ClO₃)₂ was calculated as 150 g / 232.29 g/mol, substitute that value into the equation along with the molar mass of O₂ (31.998 g/mol) to find the mass of oxygen gas formed.

Given:

The mass of oxygen  = 61.98 g

The mass of zinc chlorate = 150 grams

The balanced reaction is:

Zn(ClO₃)₂ → ZnCl₂ + 3O₂

Mol of Zn(ClO₃)₂ :

Mass: MW

150: 232.29 g/mol

0.6457

From equation, mol ratio of Zn(ClO₃)₂ → ZnCl₂ : O₂ = 1 : 3, so mol O₂ :

= 3/1 x mol  Zn(ClO₃)₂

= 3/1 x 0.6457

= 1.937

Mass of  O₂ :

Mol x MW

=1.93  x 31.998 g/mol

= 61.98 g

= (150 x 3 x 31.998) : (232.29 x 1) grams

= 14399.1: 232.29

= 61.98 g

Answer:

Mass = 40 g

Explanation:

Given data:

Mass of oxygen needed = ?

Mass of propane = 11 g

Solution:

Chemical equation:

C₃H₈ +5O₂   →     3CO₂ + 4H₂O

Number of moles of propane:

Number of moles = mass/molar mass

Number of moles = 11 g/ 44.1 g/mol

Number of moles = 0.25 mol

now we will compare the moles of propane and oxygen.

              C₃H₈        :          O₂

                  1           :            5

                0.25      :            5/1×0.25 = 1.25 mol

Mass of oxygen needed:

Mass = number of moles × molar mass

Mass = 1.25 mol × 32 g/mol

Mass = 40 g

Explanation:

Solid KMnO₄ needed = 7.9 g

Given

MW KMnO₄ = 158 g/mol

500 mL(0.5 L) of a 0.1M stock solution of KMnO₄

Required

solid KMnO₄

Solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]

Input the value :

n = M x V

n = 0.1 M x 0.5 L

n = 0.05 mol

Mass KMnO₄ :

= mol x MW

= 0.05 x 158 g/mol

= 7.9 g

The solid KMnO₄ a person need to add before filling water flask will be:

"7.9 g".

According to the question,

Molecular weight of KMnO₄ = 158 g/mol

Volume of solution = 500 mL or,

                                = 0.5 L

Molarity = 0.1 M

We know the relation,

Molarity, M = [tex]\frac{n}{V}[/tex]

or,

→ n = M × V

By substituting the values,

     = 0.1 × 0.5

     = 0.05 mol

hence,

The mass of KMnO₄ will be:

= mol × Molecular weight

= 0.05 × 158

= 7.9 g

Thus the response above is appropriate.
