Suppose that the gene for a protein 500 amino acids in length undergoes a mutation. if the mutation causes the synthesis of a mutant protein in which just one of the 500 amino acids is:__________

The four amino acids can come together in any way. 34 x 81 = 81 different combinations are conceivable.

Aspartic acid and glutamic acid are the two examples where the side chain further contains a carboxylic acid group to the one adjacent to the amino group. When the pH is close to neutral (pH 7), these groups get ionised and manifest themselves as the carboxylate anion.

The concentration of H+ ions and acid strength increase in direct proportion to the degree of dissociation (or ionisation). As a result, the degree of an acid's dissociation or ionisation is directly related to the acidity of the acid (stronger acids have lower pH values).

The atomic number of oxygen is 8. The mass number of an oxygen atom with 7 neutrons is 15.

Atomic mass is the average mass of the atom. It is measured in atomic mass units, that is Dalton. The mass number is calculated by the number of neutrons and atomic number.

The atomic number is the number of protons present in the atoms. The atomic number of oxygen is 8

The mass number can be calculated by adding those units

atomic number + number of neutrons

Mass number = 8 + 7 = 15

Thus, the mass number of an oxygen atom with 7 neutrons is 15.

Mass of water is 45.2 grams.

Overall chemical equation for reaction of combustion a propane (C₃H₈):

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.

m(C₃H₈) = 53.5 g; mass of the propane

m(O₂) = 15.0 g; mass of oxygen

m(CO₂) = 23.3 g; mass of carbon dioxide

m(H₂O) = ?; mass of water

Conservation of matter states that the mass of the reactants have to be equal to the mass of the products.

m(C₃H₈) + m(O₂) = m(CO₂) + m(H₂O)

53.5 g + 15.5 g = 23.3 g + m(H₂O)

The ph scale is based on the number of hydroxyls in the solution.

What are hydroxyls?

Chemistry and biochemistry both use the hydroxy group extensively. The chemical product generated on the largest industrial scale, sulfuric acid, among many other inorganic substances, contains hydroxy groups.

In the dehydration events that form lengthy chains out of simple biological molecules, hydroxy groups take part. A fatty acid's carboxy terminus loses its OH group when it is joined to glycerol to create a triacylglycerol. The carboxy group at the aldehyde end of one sugar loses its OH group when two aldehyde sugars are joined to create a disaccharide. The carboxy group of one amino acid loses the OH when a peptide bond is formed to join two amino acids to form a protein.

Bam's solution, 5.42 g of CsCl mixed with 35.31 ml of H2O, has a concentration of 15.3882 g CsCl/100 g H2O.

Concentration, in chemistry, is defined as the amount of solute in a particular amount of solvent or solution. Some of the most common ways to express concentration includes molarity, mass-to-mass and mass-to-volume.

To solve for the concentration of Bam's solution in g solute/100 g solvent, solve for the mass of the solvent first.

To solve for the mass of the solvent, use the density and volume:

mass solvent = density x volume

mass solvent = 0.9975 g/ml x 35.31 ml

mass solvent = 35.221725 g

Solving for the concentration of Bam's solution in g solute/100 g solvent, where the mass of the solute CsCl is 5.42 g:

concentration = mass solute/ 100 g solvent

concentration = 5.42 g/ (35.221725/100)

Explanation:

You would divide the mg by 1000 to get the number of grams.

When we double the quantities of reactants and products in a reaction,  the value of the equilibrium constant remains the same.

K = [P]/[R]

where,

[P]  is the concentration of the product.

[R] is the concentration of reactant.

If we double the quantities of reactants and products in the final concentration it'll become

[R]2=2×[R]1 and [P]2=2×[P]1

Now at initial stage

K1 =  [P1]/[R1]

at final stage after doubling the products

K2=[P2]/[R2]

Putting the given values

K2/K1 = 2×[P1]×[R1]/2×[R1]×[P1]

K2/K1=2/2

K2/K1=1

K2=K1

If there are 13 protons (positive charges), how many electrons are there in a neutral atom? Expert Answer 1)) given total number of protons =13 and electron =12 . For atom to be neutral total number of protons should be equal to total number of electrons.

Explanation:

We emphasize the valence electrons in an atom when discussing atomic properties, as they are most accessible to other atoms.

The valence electrons are the electrons that are present in the outer shell of the atoms. These electrons are free for making bonds with the electrons of other atoms.

Electrons are joined with other electrons to make a compound. These electrons are shared by or gained by other atoms.

The majority of the sun's emissions come from particles like neutrinos that travel beyond the light the sun's surface emits and can't be seen with ordinary spectroscopic instruments. As a result, to identify these particles, specialised equipment were needed, such as the Super Kamiokande (Kamioka Observatory, Japan), which has incredibly sensitive light sensors.

The pH of the solution after dilution is 1.125.

HCl is hydrochloric acid. It is known by the name muriatic acid. It is among the strong acids. It has a pungent smell and is colorless. It has a molar mass of 36.4 g/mol. It's a common reagent used in pharmaceutical industries. It is also used in other industries such as textile, rubber, and metal.

The volume of HCl added to the solution = 3.0 ml

The molar concentration of HCl = 2.5 M

Let the molar concentration of the solution after dilution is x.

The volume of the diluted solution = 100 ml.

The molar concentration of the solution after dilution is,

[tex]M _{1} V _{2} = M_{2} V _{2} [/tex]

[tex]M_{2} = \frac{ M _{1} V _{2}}{V _{2} }[/tex]

[tex]M_{2} = \frac{2.5 \times 3}{100} [/tex]

[tex] = 0.075 \: M[/tex]

Thus, the molar concentration of the solution after dilution is 0.075 M.

The pH of the solution after the dilution is,

[tex][HCl] = [H ^{ + } ] = 0.075 \: M[/tex]

[tex]pH = - log [H ^{ + } ] [/tex]

[tex]pH = - log(0.075)[/tex]
