Answer: 2.73g of CH3CH2OH Will be consumed
Explanation:
CH3CH2OH + O2 —> CH3COOH + H2O
MM of CH3CH2OH = 12 + 3 +12 + 2 16 +1 = 46g/mol
MM of O2 = 16 x2 = 32
Mass conc. Of O2 = 1.9g
From the equation,
32g of O2 consumed 46g of CH3CH2OH .
Therefore, 1.9g of O2 will consume Xg of CH3CH2OH i.e
Xg of CH3CH2OH = (1.9 x 46)/32 = 2.73g
We are asked to provide an equation for the transformation of 2-phenylethanoic acid to 2-phenylethanol. This type of a reaction is converting a carboxylic acid to an alcohol, which is classified as a reduction reaction since we are decreasing the number of bonds to oxygen in the molecule. In order to reduce a carbonyl to an alcohol, we need a source of hydride, H⁻. Reducing the carboxylic acid once will convert it to the aldehyde. However, we need to reduce the functional group all the way down to an alcohol, which is another reduction step after aldehyde formation. Therefore, the hydride source of choice is lithium aluminum hydride, LiAlH₄.
A reaction scheme is provided to show the reaction of the reduction of carboxylic acid to alcohol. The first step is addition of lithium aluminum hydride which does the reduction, and the second step is a work-up of acid which protonates the alcohol to get the final product.
Other commonly used units include g/L (grams of solute per liter of solution) and m/L (moles of solute per liter of solution). Solubility units always express the maximum amount of solute that will dissolve in either a given amount of solvent, or a given amount of solution, at a specific temperature.

Answer:
Explanation:
Of the numerous sorts of RNA, the three most well-known and most commonly examined are delivery person RNA (mRNA), exchange RNA (tRNA), and ribosomal RNA (rRNA), which are show in all living beings. These and other sorts of RNAs essentially carry out biochemical responses, comparative to proteins.
