Answer:

The correct answer is "0.0179".

Explanation:

The given reaction is:

⇒ CO_2(g) + C(s) \rightleftharpoons  2 \ CO(g)

The given value is:

At 727°C temperature,

Kp = 1.47

As we know,

Gas constant,

R = 0.0821 L atm/mol.K

Temperature,

= 727+273

= 1000 \ K

Now,

The change in moles will be:

⇒ \Delta n=Products-reactants

⇒       =2-1

⇒       =1

As we know,

⇒  K_p=K_c(RT)^{\Delta n}

On substituting the given values, we get

⇒  1.47=K_c(0.0821\times 1000)^1

⇒    K_c=\frac{1.47}{0.0821\times 1000}

⇒          =\frac{1.47}{82.1}

⇒          =0.0179

What are the products of this reaction? (High temperature)<br> Na2SO4 * 10H2O + C —&gt; ????
Thepotemich [5.8K]

Answer:

A chemical equation can be described as a symbolic representation of a chemical reaction. It can be written in the form of words or symbols.

The following chemical reaction can be completed as :

Na2SO4·10H2O + 2C = Na2S + 10H2O + 2CO2

Sodium Sulfate Decahydrate + Diamond = Sodium Sulfide + Water + Carbon Dioxide

The products of the reaction are:

  • Sodium Sulfide (Na2S)
  • Water (H2O)
  • Carbon dioxide (CO2)

Describe the difference between a reaction that occurs spontaneously and one that does not
lidiya [134]
2.B. Describe the difference between a reaction that occurs spontaneously and one that does not. Spontaneous chemical reactions release energy and use that energy to power itself; non-spontaneous chemical reactions need to absorb energy, which they can't absorb their own energy that they don't even have.

3. A mass of 0.15 ounces is equal to how many grams?
garik1379 [7]

Answer:

Option C = 4.25 g

Explanation:

Ounce and grams are unit of mass. Ounce is larger unit while gram is smaller unit. The one ounce is consist of 28.35 g or we can say that one ounce is equal to 28.35 g. In order to convert the given ounce value into grams the value is multiply with 28.35 g.

Given data:

Mass = 0.15 ounce

Mass in gram = ?

Solution:

One ounce is equal to 28.35 g, so

0.15 × 28.35 = 4.25 g
