Answer:

Amino acids join by linking the acid group of one amino acid to the amino group of another.

Explanation:

Amino acids are organic molecules that form the basic molecules for making proteins and there are. An amino acid comprises of an acidic carboxyl (-COOH) functional group and an amino group (-NH2)  as well as a side an organic side chain (R group).

In the formation of proteins, several amino acids join together by the formation of peptide bonds between each amino acids to form a long polypeptide. These peptide bods are formed by the linking of the acidic carboxyl group of one amino acid to the amino group of another amino acid, during this process water is removed.

timama [110]

Answer:

Silver, 0.239 J/(g °C)

Explanation:

  • The heat change is related to specific heat as given by the formula;

Heat change = mass of substance × specific heat × change in temperature

  • Therefore; considering same amount of substance or equal masses and have the same initial temperature.
  • The change in temperature will be inversely proportional to the specific heat.
  • Therefore; the higher the specific heat lower the temperature change.
  • Hence,  the change in temperature will be highest for the substance with the lowest specific heat.

Therefore; the one that will increase in temperature the most is Silver

How many moles of water are in 1.23x10^18 water molecules
Harlamova29_29 [7]

By 1.23 x 1024 you mean 10 to the power of 24 molecules? If so all you need to do is divide the number of molecules you have by Avagadros number, 6.022 x 10^23. This will give you the mols of water, or the mols of anything, since there is always 6.022 x 10^23 molecules in 1 mol of substance.


1.23x10^24 atoms/6.022x10^23 atom/mol = 2.04 mol H20

allochka39001 [22]

Answer:

B. CO₂ and H₂O.

Explanation:

When any organic substance undergoes complete combustion, it produces carbon dioxide (CO₂) and water (H₂O).

In the case of methane, the balanced reaction is:

  • CH₄ + 2O₂ → CO₂ + 2H₂O

With the above information in mind the correct answer is option B. CO₂ and H₂O.

When the combustion is incomplete, carbon monoxide (CO) is produced as well.

iragen [17]

The first blank can be filled with the Heliocentric model, and the second blank can be filled with Copernicus.  

The heliocentric model known as heliocentrism was proposed by the Renaissance astronomer, mathematician, and the Catholic cleric Nicolaus Copernicus resulting in the Copernican revolution.  

It is the astronomical model, in which the planets and the Earth revolve around the Sun positioned at the middle of the Solar system. Factually, the heliocentric model was in contrast to geocentrism, in which Earth is positioned at the center of the Solar system.
