Is ninhydren test positive for protein?

lyudmila [28]

The Ninhydrin test is not effective to detect high molecular weight proteins as the steric hindrance limits the ninhydrin from reaching the α-amino groups.

n the balanced equation 4Fe + 3O2à 2Fe2O3 , how many atoms of iron (Fe) are reacting with every three molecules of oxygen (O2)?

s2008m [1.1K]

Answer is: four iron atoms <span>are reacting with every three molecules of oxygen.
Balanced chemical reaction: 4Fe + 3O</span>₂ → 2Fe₂O₃.
From chemical reaction: n(Fe) : n(O₂) = 4 : 3.
Ratios of atoms of iron and molecules of oxygen is 4 : 3..
There is four atoms of iron and six atoms of oxygen on both side of reaction.

What is an important function and mitochondrion

Alenkasestr [34]

"Function. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle."

Why does naphthol react with sodium hydroxide? why does ethanol not react to the extent that naphthol does with sodium hydroxide

igomit [66]

Answer:

Conjugate base of naphthol is highly stable but conjugate base of ethanol is unstable.

Explanation:

Naphthol gives acid base reaction with NaOH where naphthol acts as an acid and NaOH as a base.

Reactivity of naphthol towards NaOH is quite high because the conjugate base of naphthol is highly stable. Stability of the conjugate base arises due to delocalization of negative charge on oxygen atom into aromatic naphthalene ring.

Ethanol is not so reactive towards NaOH because the ethoxide ion is highly unstable due to lack of delocalization of negative charge on oxygen atom.

Resonance structures of conjugate base of naphthol has been shown below.
