For a mixture of 2.0 mol of CO(g) and 2 mol of H2O(g) was allowed to come to equilibrium in a 1.0L flask at a high temperature. the molar concentration of H2(g)  is mathematically given as

[H2] = x = 1.33 M

<h3>What is the molar concentration of H2(g) in the equilibrium mixture?</h3>

Generally, the equation for the Chemical reaction  is mathematically given as

Kc = [CO2]*[H2]/[CO]*[H2O]

Therefore

4.0 = (1*x)^2/(2-1*x)^2

x = 1.33

In conclusion, the molar concentration

[H2] = x = 1.33 M

439.3 g CO2

Explanation:

First find the # of moles of CO2 that results from the combustion of 3.327 mol C3H6:

3.227 mol C3H6 × (6 mol CO2/2 mol C3H6)

= 9.981 mol CO2

Use the molar mass of CO2 to determine the # of grams of CO2:

9.981 mol CO2 x (44.01 g CO2/1 mol CO2)

= 439.3 g CO2

5. Balance the following reactions using either the oxidation number method or the half-reaction
stich3 [128]

The balanced reaction equations are;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

<h3>What is a balanced redox reaction?</h3>

A redox reaction is said to be balanced when the number of electrons gained is equal to the number of electrons lost.

Let us now write the balanced reaction equations one after the other. Thus;

a) 4 NaClO + H2S → 4 NaCl + H2SO4

b)6Ce^4+ + I^– + 6OH^– → 6 Ce^3+ + IO3^– + 3H2O

Which is a common unbalanced force acting on objects in motion?
Semmy [17]

Answer:

a. friction

Explanation:

What is a common unbalanced force acting in motion? Common forces that are often unbalanced include the force of gravity and applied forces. When these forces are unbalanced, objects accelerate, change their position and find new configurations for which all forces are again balanced.

Friction is a kind of force.

Which property determine am atoms ability to attract electrons shared in a chemical bond?
brilliants [131]
Hello there!

Electronegativity is what determine's an atoms ability to attract electrons shared in a chemical bond.Ionization, atomic radius, and also <span> ionic radius both would not determine this as they wouldn't have any similar bond that would attract.
</span><span>
Your correct answer would be (option c)

</span><span>A. ionization 

B. atomic radius

C. electronegativity

D. ionic radius
