4Fe+3O₂⇒2Fe₂O₃

CO₂+2Cl₂⇒O₂+CCl₄

<h3>Further explanation  </h3>

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

For simple equations, you can experiment with the balance of the number of atoms on the left and right

4Fe+3O₂⇒2Fe₂O₃

CO₂+2Cl₂⇒O₂+CCl₄

  • with variable :

aFe+bO₂⇒Fe₂O₃

Fe , left=a, right=2⇒a=2

O, left=2b, right=3⇒2b=3⇒b=3/2

the equation :

2Fe+3/2O₂⇒Fe₂O₃   x2

4Fe+3O₂⇒2Fe₂O₃

aCO₂+bCl₂⇒O₂+CCl₄

C, left=a, right=1⇒a=1

Cl, left=2b, right=4⇒b=2

O, left=2a, right=2⇒2a=2⇒a=1

the equation :

CO₂+2Cl₂⇒O₂+CCl₄

Which of the following are not at equilibrium? Check all that apply. Check all that apply. The concentrations of reactants and t
tatyana61 [14]

The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal. and these reactions are not at equilibrium.

<u>Explanation:</u>

The conditions to attain equilibrium is that,

  • Conversion of reactant to product and vice versa occurs at the same rate.
  • The system is a closed system.
  • The temperature remains constant.
  • Concentration of every substance remains constant.
  • Rate of forward and reverse reactions will be different.

So the answer is The concentrations of reactants and the products are not constant and the rates of the forward and reverse reactions are equal.
