carl creates the model of a diamond shown below. his model shows atoms of carbon in a crystalline structure. what can carl determine about diamonds using his model?

group of answer choices

a diamond is a mixture because it is made of compounds.

a diamond is an impure substance because it made of mixtures.

a diamond is a pure substance because it is made of one element.

a diamond is a mixture because it is made of elements.

(here is the pic)

A diamond is a pure substance because it is made of one element.

Explanation:

From the crystalline structure model of the diamond, we can see that we only have just one element represented by the green balls connected in a cross linked fashion to one another. Therefore, one can rightly conclude that this is a pure substance made up of one element.

In a pure substance, all parts are homogeneous and composition is definite.

i think it is true since you can test the answer and can use observations to complete it.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
