<h3>What does the chemistry term "equation" mean?</h3>
Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.
<h3>Equation and response are what?</h3>
What is an equations and a chemical reaction?

physical, mathematical, and conceptual are the 3 types of models an example of a conceptual model is a model of our solar system or even a rocket a limitation of them is they are not realistic in scale but allow us see arrangements of things. mathematical models could be something like a formula graph charts ect we benefit from the visual steps however the downfall is there's lots of user error and a physical model is something like an atom model it allows to see the thing but it's physical states limits us
The correct answer would more than likely have to be true, i’ve had this question before not to long ago.
