No, the correct answer is B. Physical change because the identity of the substance does not change.
For example, if you take a piece of paper and tear it in half you actually changed its property because now those pieces of paper have half the weight and and size that they did before you did anything. Now you know its a physical change because its still paper all you have done is change the physical appearance.
Hope this was helpful(;
If no one knows try to do research or sum
Answer:
We will have zero bonds
Explanation:
In this case, we have to start with the <u>structure of 4,5-diethyloctane</u>. This name ends with the <u>suffix "ane"</u> therefore we have an <u>alkane</u>. All the alkanes are made with <u>single bonds</u> between carbons and <u>single bonds</u> between carbon and hydrogen.
The molecule will have a <u>carbon chain of eight carbons</u> and we will have 2 <u>branches</u>, one ethyl on carbon 4 and another ethyl on carbon 5. (see figure 1)
Hey there!:
1) The additional stability that accompanies the formation of the network<span>Crystalline is measured as network enthalpy.
</span>2) The reticular energy is the energy released when the solid Crystal isform from separate ions in the gaseous state. Always exothermic.<span>
3) </span>The enthalpy of the network depends directly on the size of the loads and conversely in the distance between the ions .
hope this helps!
