What coefficients can be used to balance the following equation
zheka24 [161]

The coefficient that can be used to balanced the given equation are 3, 2, 6, 1

<h3>What is a chemical equation? </h3>

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

<h3>How to balance the equation </h3>

K₂CO₃ + FeCl₃ -> KCl + Fe₂(CO₃)₃

There are 3 atoms of C on the right side and 1 on the left side. It can be balanced by writing 3 before K₂CO₃ as shown below:

3K₂CO₃ + FeCl₃ -> KCl + Fe₂(CO₃)₃

There are 6 atoms of K on the left side and 1 on the right side. it can be balanced by writing 6 before KCl as shown below:

3K₂CO₃ + FeCl₃ -> 6KCl + Fe₂(CO₃)₃

There are 6 atoms of Cl on the right side and 3 on the left. It can be balanced by writing 2 before FeCl₃ as shown below:

3K₂CO₃ + 2FeCl₃ -> 6KCl + Fe₂(CO₃)₃

Now the equation is balanced.

Thus, the coefficients are; 3, 2, 6, 1

Dovator [93]
Coal a is a chemical compound. It is pure carbon. You cannot separate carbon into other molecules without changing its chemical consitution.

Petroleum is a mixture of many chemical compounds, hydrocarbons, plus other elements. Petroleum components contain carbon, hydrogen, oxygen, nitrogen, sulfur, and some metal traces. The different compounds that consitute the petroleum can be separated by physical media like distillation.

Please help thank you
maxonik [38]

Answer:

K=1.7x10^{-3}

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve this problem by firstly setting up the equilibrium expression for the given reaction, in agreement to the law of mass action:

K=\frac{[NO]^2}{[N_2][O_2]}

Next, we plug in the given concentrations on the data table to obtain:

K=\frac{(0.034)^2}{(0.69)(0.98)}\\\\K=1.7x10^{-3}

Regards!
