Answer:

2 grams of salt must be added by chef  to make the recipe noticeably saltier.

Explanation:

Weber's Law :

k=\frac{\Delta I}{I}

Where =

I = Initial stimulus intensity

ΔI = Difference threshold

k = Weber constant

According to Weber’s constant for saltiness , k= \frac{1}{5}

Amount of salt required for the recipe , I= 10 g

\frac{\Delta I}{10 g}=\frac{1}{5}

\Delta I = 2 g

2 grams of salt must be added by chef  to make the recipe noticeably saltier.

Answer:

Josue

Explanation:

J.J Thompson proposed the plum pudding model of the atom. In his proposition, the atom is a sphere of positive charges into which negative charges were embedded. This model of the atom did not significantly contribute to our present day understanding of atomic structure.

On the other hand Ernest Rutherford laid out the foundation for a more accurate understanding of atomic structure in his nuclear model of the atom. According to Rutherford, the atom consists of a positively charged massive core called the nucleus around which electron move in orbits. His idea was akin to the solar system with the sun at it's core and planets moving around the sun in orbits.

This his idea of the nuclear theory was held as fundamentally correct by Neils Bohr's model of the atom. Hence, his nuclear theory of the atom was a significant milestone in our present day understanding of atomic structure.

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5
djyliett [7]

Question:

What type of product forms in the intramolecular reaction between the aldehyde portion of the glucose molecule below and its C-5 hydroxyl group?  

a. disaccharide

b. carboxylic acid

c. hemiacetal

d. ester

e. stereoisomer

Answer:

hemiacetal  forms in the intramolecular reaction between the aldehyde portion of the glucose molecule and its C-5 hydroxyl group

Explanation:

It is an alcohol also an ether that has been attached to the carbon molecule. Here the hydrogen has occupied the fourth bonding position. This hemiacetal has been derived from the aldehyde. Hence, hemiketal being an alcohol as well as ether has been attached to the same carbon and also to the two other carbon.
