when two amino acid monomers are positioned so that the carboxyl group of one is adjacent to the amino group of the other, they
zalisa [80]

They can be joined through a Peptide bond

The amino acids serve as the foundation for proteins. Water is produced when the amino acids are linked to form a lengthy chain of acids via amino and carboxyl. The main protein is made up of these long chain amino acids.

When the carboxyl group of one molecule combines with the amino group of the other molecule, a molecule of water is released, and a peptide bond is created between the two molecules (H2O). This condensation event, sometimes referred to as a dehydration synthesis reaction, typically takes place between amino acids.

<h3>What is a Peptide bond ?</h3>

The carboxyl group of one amino acid is joined to the amino group of another to produce a peptide bond, also known as a eupeptide bond. In essence, a peptide link is an amide-type covalent chemical bond.

How did the surface area of the metal strip expose to the solution affect the
frez [133]

Answer:

See explanation below

Explanation:

In an electrochemical cell, electricity is obtained by the gradual deterioration of the anode.

Hence, surface area of the metal will affect the length of time within which the electrochemical cell works.

The greater the surface area of the metal, the longer the electrochemical cell can function and the greater the quantity of electricity produced, hence the answer above.

What is the application of the emission spectra regarding elements?
malfutka [58]

The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy state to a lower energy state. The photon energy of the emitted photon is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each transition has a specific energy difference. This collection of different transitions, leading to different radiated wavelengths, make up an emission spectrum. Each element's emission spectrum is unique. Therefore, spectroscopy can be used to identify elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances.

Calculate the molecular mass of carbon monoxide (CO) by adding the atomic mass of carbon (C) and the atomic mass of oxygen (O):
Bond [772]

 The   molecular   mass  of carbon monoxide (CO)  is  28 g/mol


   <u><em>calculation</em></u>

The  molecular  mass  of CO =  atomic mass  of C + atomic  mass  of O

From  periodic table the atomic  mass  of  C = 12 g/mol and for O = 16 g/mol


Therefore the molecular  mass   of Co = 12 g/mol + 16 g/mol = 28 g/mol
