The equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.
<h3>What is a chemical reaction?</h3>
The term chemical reaction has to do with the combination of substances to give products. We know that reactants and products must follow the law of conservation of mass.
Hence, the equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.

Answer: 
is a reactant; it is present before the reaction occurs.
Explanation:
In a chemical reaction the chemical formulas written before the arrow are described as reactants as they react together to form products which are written after the arrow.
Thus and HCl are reactants here whereas 
, 
and 
are products.
Answer: D!! ( difference in the potential energy of the reactants and products )
Explanation:
i have the same test
When they ask you for the solution they are usually asking for x. So solve for X.
X=-12 so you only have one solution. so the answer is B
Im guessing it might be 98.4x0.58, when you rearrange the pressure formula.
