Answer:
Heterogeneous mixture.
(The composition is not uniform.)
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
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
In a balanced chemical equation, the numbers of individual particles and the numbers of moles of particles are represented by the COEFFICIENTS.

<span>all the ones that phase down are exothermic - freezing, deposition, condensation.
all the ones that phase up are endothermic - melting, sublimation, vaporization
endothermic is to gain heat, exothermic is to release heat</span>
