In "condensed structural formula" each carbon atom and its attached hydrogen atoms are written in group in the linear form is correct about organic chemistry.
Option B
<u>Explanation</u>:
"condensed structural formula" is a method of writing or presenting organic structures in line of text. It presents all the atoms, but excludes the vertical bonds and all the horizontal single bonds. In condensed structural formula, or we can say semi-structural formula, covalent bonds are not always presented or shown. When the formula or representation is written in line with covalent bonds being shown, then it is referred to as linear formula. For example- the condensed structural formulas of ethane, propane, and ethanol is written as follows:-

Apart from these Statement, all others are false because they do not have any logic with respect to organic chemistry.
None. It's the O horizon. Compromises of mostly decomposed plant litter.
Answer : The number of moles of
formed are, 0.69 moles.
Explanation : Given,
Moles of
= 0.345 mol
Now we have to calculate the moles of 
The balanced chemical equation is:

From the balanced reaction, we conclude that
As, 1 mole of
react to give 2 moles of 
So, 0.345 mole of
react to give
mole of 
Therefore, the number of moles of
formed are, 0.69 moles.
Answer:
The fatty acids and glycerol contributes to soap’s slippery texture.
Explanation:
- What we need to know is that every oil has a specific index for strength, cleaning, etc.
- All of them are determined by the amount of certain fatty acid in the oil.
- When we make soap, what we need to know is that oil has a special role to play in that soap.
- So for example some of those oils are used to make bubble soap or creamy soap.
- On the other side, there are some oils which are giving strength to soap.
The volume of the nail since it is an irregular figure you can't measure it like a regular object.
