Chemistry
1 answer:
Lapatulllka [165]4 years ago
4 0

Answer:

Neutrons = ( Atomic mass – Atomic number ) ( A–Z )

Protons and Electrons are equal to the atomic number

For example Neon,

Mass number (A) = 20

Atomic Number (Z) = 10

Number of Protons = 10

Number of Electrons = 10

Number of Neutrons = ( A–Z ) = 10

Electronic distribution :

K= 2

L= 8

A phospholipid molecule has a polar and a nonpolar end. Because of this, water molecules form-polar bonds with the nonpolar end
Lady bird [3.3K]

The right answer is Hydrogen bonds with the polar end of the phospholipid molecule.

A phospholipid contains a phosphoric acid group as mono or di-ester.  

The physicochemical properties of phospholipids depend both on the polar molecule of the hydrophilic head and on the aliphatic chains of the hydrophobic tails. In an aqueous medium, such amphiphilic molecules tend to be organized so that only their hydrophilic head is in contact with the water molecules, which typically results in structures in micelle, liposome or lipid bilayer.

What do cations and anions form?
melomori [17]

Answer: Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.

What reacts at room temperature with ethanol and also with ethanoic acid<br><br>​
solniwko [45]

Answer: Its esterification reaction.

when organic acid react with alcohol it forms ester and water. reaction is known as esterification reaction.

CH3COOH + C2H5OH → CH3COOC2H5 + H2O

ethanoic acid + ethanol → ethyl acetate + water

this reaction takes place in the presence of acid catalyst ( dil H2SO4).

in this reaction oxygen of ethanol with lone pair act as nucleophile and carbonyl carbon of acetic acid act as electrophile.. so its nucleophilic substitution reaction of -COOH group.
