Ahat [919]3 years ago
3 0

Answer:

Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces. These forces keep particles close together.

Which one of the following statements is not correct?
sweet [91]

Answer:

option a, During allotropic transformation, the number of atoms in the material changes.

Explanation:

Allotrops are different crystalline forms of the same element. So, two allotrops of an element have same number of atoms.

for example diamond, graphite, graphene, fullerene are allotropic forms of carbon.

Allpotops differ in physical and chemical properties. So, volume changes during alloptropic transformation. So, statement b is correct.

Allotropic transformation is the transformation of one allotropic form to other therefore, number of atom does not change during allotropic transformation.

Chemical species having same atomic number or same no. of protons are called isotopes. so statement c is correct.

When an electron is added to the neutral element, electronic repulsion increases which lead to the increase in atomic size, So, statement d is also correct.

So among given, option a is incorrect

What is the net charge of the peptide arg-ala-phe-leu at ph 8?
adell [148]
The structure of this oligopeptide is attached:

It consists of arginine - alanine - phenylalanine and leucine

From the picture we can see that N terminus charge is +1
Also Arginine is considered as basic amino acid with charge +1
C terminus charge is -1

At pH = 8, the whose pKa are less than pH will be deprotonated and the net charge will be +1 

So the net charge of this oligopeptide is +1 at pH = 8
