The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.

First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.

Next, you should research this topic and look at the factors that make it up.

After that, you can create your template as follows:

  • Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.
  • Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.

You can see examples of "Conservation of Masses,"  models in the attached figure.

A particular reaction, a → products, has a rate that slows down as the reaction proceeds. the half-life of the reaction is found
irga5000 [103]
Generally, the rate of a reaction will decrease with increasing temperature, although there are some exceptions in the case of non-elementary reactions. However it is more likely that the first statement is false.
Half-life is a measure of the time taken for a to reach 1/2 of its initial concentration, and is generally completely independent of reagent concentration within a first order reaction, which is likely what this reaction is, therefore statement 2 is also likely false.
Hope this helps!

In the following reaction, 2NaCl 2Na + Cl2 sodium and chlorine are products, salts, reactants, or ions?
avanturin [10]

The answer is: sodium and chlorine are products.

Balanced chemical reaction of sodium chloride decomposition:

2NaCl → 2Na + Cl₂.

Decomposition is reaction where one substance is broken down into two or more simpler substances.  

From one chemical compound (in this example sodium chloride) two new substances (sodium and chlorine) are produced.

Ming has two unknown substances. One is nonpolar, and the other is polar.
Verdich [7]
Hello
We know that polar molecules' attraction is stronger than that of non polar ones; this can be a good basis for us to check the substances' polarity. Knowing that polar forces are stronger, we can eliminate all options referring to them as being the weaker force; that is, options C and A. Next, we know that stronger forces will result in lower volatility so we can eliminate option D. The answer is B, assuming the compound has an odor.
