The answer is A) Both formulas identify the specific in a particular compound. However, a 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).

When a soda can is dropped, it should not be immediately opened. Why?

Kipish [7]

The pressure inside a coke bottle is really high. This helps keep the soda carbonated. That is, the additional pressure at the surface of the liquid inside the bottle forces the bubbles to stay dissolved within the soda. When the coke is opened, there is suddenly a great pressure differential. The initial loud hiss that is heard is this pressure differential equalizing itself. All of the additional pressure found within the bottle pushes gas out of the bottle until the pressure inside the bottle is the same as the pressure outside the bottle. However, once this occurs, the pressure inside the bottle is much lower and the gas bubbles that had previously been dissolved into the soda have nothing holding them in the liquid anymore so they start rising out of the liquid. As they reach the surface, they pop and force small explosions of soda. These explosions are the source of the popping and hissing that continues while the soda is opened to the outside air. Of course, after a while, the soda will become "flat" when the only gas left dissolved in the liquid will be the gas that is held back by the relatively weak atmospheric pressure.

Elza [17]

Answer:

Explanation:

Oleic acid originates from an unsaturated fatty acid with 18 carbon atoms and one double bond, which can be found in olive oil and many other vegetable and animal oils and fats. Its economic importance includes the production of soap making and cosmetics etc.

The line-bond structure of the given oleic acid in the question can be found in the attached below.

1 mole = 1000 millimoles (mmol); 1millimole = 1000 micromoles (µmol). if a solution contains 38231 µmol, what is that amount in

Mrrafil [7]

1 mmol --------------------- 1000 µmol
( mmol ) -------------------- 38231 µmol

mmol = 38231*1 / 1000

mmol = 38231/ 1000

=> 38.231 mmol
