Answer:
they explain the properties and structure of the compound which empirical molecular formulars cannot explain
The structural formulas are good for depicting polymers because polymers are the chemical compounds attached to the long chain with ac other which is impossible to represent other than the structural formula.
What are structural formulas?The structural formulas are the graphic representation or diagrammatical representation of the structure of any chemical formula in organic and inorganic chemistry they are mostly used.
In Polymers, they are long chains of chemicals compound can be shown diagrammatically or graphically to understand the attachment t of the bonds within them which signifies the physical properties too.
Therefore, polymers are the chemical compounds attached to the long chain with ac other which is impossible to represent other than the structural formula which is why structural formulas are good for depicting polymers.

If a person consumes 50% of their daily kilocalories from carbohydrates and 30% from protein, what percentage of their daily kilocalories will come from fat?
The percentage of daily kilocalories of the person that come from fat is 20%.
The diet of a person is composed mainly of carbohydrates (C), proteins (P) and fat (F), that is, the sum of the 3 sources amount to 100% of the consumed kilocalories. Given that 50% of the daily kilocalories of this person come from carbohydrates and 30% come from protein, the percentage that comes from fats is:
[tex]C + P + F = 100\%\\F = 100\% - C - P\\F = 100\% - 50\% - 30\% = 20\%[/tex]
The percentage of daily kilocalories of the person that come from fat is 20%.

When a metal such as copper is heated,it expands. Can anyone tell me what happens to the metal particles as the solid metal expands?
Answer:
The metal molecules inside start to vibrate faster, causing the solid to change to liquid if exposed to the intense temperature over a long period of time.
Explanation:
As my answer states, but for an explanation, lets say you are boiling an ice cube, it will start to turn into liquid water, that is because it has been exposed to that heat for a long period of time. The same will happen for the metal, if its exposed for long enough, it will turn into a liquid, then can be turned into a gas because the molecules are vibrating so quickly that they start to easily move apart.
Hope this helps, let me know if any more clarification is needed.
