The answer is A) Both formulas identify the specific in a particular compound. However, a <span>structural formula also shows how the atoms in a compound are bonded together.

Molecular formula: 
Advantage: shows chemical composition
Disadvantage: No structural information

Structural formula:
Advantage: shows chemical connectivity
Disadvantage: Minimal three dimensional

Answer: the correct  answer is (A).

Explanation:

Structural formula not only tells us about the number and types of atoms in a molecule but also tells us about the bonded positions of all the atoms in a molecule of that particular compound.

Molecular structure only tells us about the numbers of atoms and types of atoms present in a molecule of that particular compound.

For example: Molecular formula of propanone and propanal are same that is C_3H_6O but structural formula is different that CH_3COCH_3 for propane and CH_3CH_2CHO for propanal. Here structural formula is showing that how the atoms in propanone and propanal are bonded together.

Hence, the correct answer is option (A).

EXPERIMENT: DETERMINING VOLUME
Tanzania [10]

Explanation:

(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?

<u>(Ans- A)</u> <em>Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.</em>

(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?

<u>(Ans-B)</u> <em>It will work for both regular and irregular shaped objects since both displace equal volumes of water.</em>

(Ques - C) Is one method of measurement more accurate than the other? Why or why not?

<u>(Ans-C)</u> <em>Both are pretty accurate, with some experimental errors which may creep in accidentally. </em>

(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?

<u>(Ans - D)</u> <em>No, the method would not work because sugar being soluble, will dissolve in water. </em>

<em>No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.</em>

(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.

<u>(Ans- E)</u> <em>I learnt about determining volume of different objects from this investigation. </em>(Sorry, I know its not a very thoughtful answer)
