The polymerization of amino acids produces:
Delicious77 [7]

Answer:

Proteins

Explanation:

Polymerization, in chemistry, is the chemical combination of monomeric units to form a polymer. Polymers are large molecules made up of smaller units called monomers. Amino acids are the monomeric units of proteins i.e. A protein is made up of of many amino acids joined together.

Therefore, the chemical combination of amino acids will form a peptide bond between the carbon atom of the acid group and nitrogen atom of the amine group in the structure of the amino acids. This is done by the loss of a water molecule. The continuous repetition of this polymerization process will form a chain called polypeptide, which is the PROTEIN.

The equilibrium constant (Kp) for the decomposition of phosphorus pentachloride (PCl5) to phosphorus trichloride (PCl3) and mole
Oksanka [162]

Answer: The partial pressure of Cl_2 is 1.86 atm

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_c

The given balanced equilibrium reaction is,

                            PCl_5(g)\rightleftharpoons PCl_3(g)+Cl_2(g)

Pressure at eqm.     0.973 atm                 0.548atm      x atm

The expression for equilibrium constant for this reaction will be,

K_c=\frac{(p_{PCl_3}\times (p_{Cl_2})}{(p_{PCl_5})}

Now put all the given values in this expression, we get :

1.05=\frac{(0.548)\times (x)}{(0.973)}

By solving the term 'x', we get :

x = 1.86 atm

Thus, the partial pressure of Cl_2 is 1.86 atm

The experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimenta
olasank [31]

Answer:

An experiment is a research method performed within a completely controlled environment that uses groups of individuals ( subjects), one of which the factors being tested are not spplied on, an independent factor of the hypothesys ( to be tested ), for example the resilience of a group of teenagers) and a dependant factor that is applied to check how it varyes depending on the tested factor ( for example, the most challanging experience of their generation)

Perform the following operation and express the answer in scientific notation. 7.0x10^3x1.1x10^7
dimulka [17.4K]

Answer:

The answer is: 7.7\times10^{10}

Explanation:

Scientific notation is of the kind: a.bc\times10^{x}

The given calculation:

7.0\times10^{3}\times1.1\times10^{7}=(7\times1.1)\times10^{(3+7)}

=7.7\times10^{10}

Therefore, the answer in scientific notation is: 7.7\times10^{10}
