A. AlCl3 the more ions that dissociate in the water, the lower the freezing points becomes. AlCl3 has 4 ions which has the most out of all the other answer choices.
The answer is Mixture.

A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

Answer:
the change in energy of the gas mixture during the reaction is 227Kj
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
Measurements show that the enthalpy of a mixture of gaseous reactants increases by 319kJ during a certain chemical reaction, which is carried out at a constant pressure. Furthermore, by carefully monitoring the volume change it is determined that -92kJ of work is done on the mixture during the reaction. Calculate the change of energy of the gas mixture during the reaction in kJ.
From thermodynamics
ΔE= q + w
Where w= workdone on the system or by the system
q= heat added or remove
ΔE= change in the internal energy
q=+ 319kJ ( absorbed heat is + ve
w= -92kJ
If we substitute the given values,
ΔE= 319 + (-92)= 227 Kj
With the increase in enthalpy and there is absorbed heat, hence the reaction is an endothermic reaction.
