Using the two amino acids alanine and glycine, show a dehydration synthesis reaction forming a dipeptide. Draw the dipeptide of two amino acids joined together by a peptide bond. Label the peptide bond with an arrow. The position of the peptide bond is also the place in the molecule where a water molecule was removed and the two amino acids were joined by a dehydration synthesis reaction (also sometimes referred to as a condensation reaction).

Answer: [tex]2.00x10^{2}[/tex]

Explanation: 1 gram is equal to 1000 Milligrams so

[tex]0.00200g=\frac{1000mg}{1g}[/tex]

Since you go straight across its just multiplication so 0.00200x1000=200mg

To answer it in scientific notation it should just be [tex]2.00x10^{2}[/tex] mg

Taking into account the definition of molar concentration and molar mass, the mass of potassium hydroxide, KOH, required to prepare 174.59 cm³ of a 0.864 mol/dm³ solution is 8.45988 grams.

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by:

Molarity= number of moles÷ volume

The molar mass of substance is defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

In this case, you know that:

Replacing in the definition of molar concentration:

0.864 mol/dm³= number of moles÷ 0.17459 dm³

Solving:

0.864 mol/dm³ ×0.17459 dm³= number of moles

0.1508 mol= number of moles

The molar mass of KOH is 56.1 g/mol. So, you can apply the following rule of three: If by definition of molar mass 1 mole of the compound contains 56.1 grams, 0.1508 moles of the compound contains how much mass?

mass= (0.1508 moles×56.1 grams)÷ 1 moles

mass= 8.45988 grams

In summary, the mass of potassium hydroxide, KOH, required to prepare 174.59 cm³ of a 0.864 mol/dm³ solution is 8.45988 grams.

The mass of the solid will be 114.7 g.

The density of a substance is given as the ratio of its mass and its volume.

Also, a solid will always displace its own volume in a liquid.

Mass of liquid solvent = 47.3 g

Density of liquid solvent = 0.865 g/mL

Recall that: density = mass/volume

Volume of liquid solvent = mass/density

                                     = 47.3/0.865

                                      = 54.7 mL

Volume of solid + liquid solvent = 90.0 mL

Volume of solid = 90.0 - volume of liquid solvent

                            = 90.0 - 54.7

                               = 35.3 mL

Density of solid = 3.25 g/mL

Mass of solid = density x volume

                       = 3.25 x 35.3

                          = 114.7 g

The mass of the solid is 114.7 g.

The total mass in micrograms of cofactor A in a yeast colony containing 10^5cells is 2.47 ug.

As a cofactor for several oxidative and biosynthetic activities in intermediate metabolism, coenzyme A (CoASH) has a distinct function. When acyl-CoA thioesters are produced from organic carboxylic acids, the acid is activated for additional biotransformation processes and enzyme recognition is facilitated.

A coenzyme is an organic, non-protein molecule that an enzyme needs in order to carry out its catalytic function. An enzyme is a protein that serves as a catalyst to speed up biological reactions without changing itself in the process.

Competition occurs when individuals of different species struggle to obtain the same resource in an ecosystem (such as food or living space). Adaptations, such as physical mutations and behavior modifications, can help an organism outcompete its competitors. 

The correct answer is M^-1s^-1.

The proportionality constant in the rate law expression, known as the rate constant or the particular rate constant, represents the relationship between the rate of the reaction and the concentration of the reacting species. Because it equals the rate of the reaction when the concentration of the reactants is assumed to be unity, it is known as the specific rate constant. The speed and direction of a chemical reaction are measured by a reaction rate constant. We are aware that the values of the Rate constant vary with temperature.

The given rate law is:

Rate = k[A][B]

The units of rate are always Ms^-1 and the units of [a] are mol so: mol*s^-1

Putting the units in the given rate law:

Rate = k[A][B]

Ms^-1=k×(M)×(M)

Explanation:

To find the weight percent (aka. mass percent), you need to use the following equation:

                                   mass of solute (g)
Weight Percent  =  ----------------------------------  x  100%
                                  mass of solution (g)

In this case, the solute is sugar and the solution is the sugar and water. You can find the weight percent by plugging the given values into the equation and solving. The final answer should have 3 sig figs like the given values.

mass of solute = 15.0 g

mass of solution = 15.0 g + 50.0 g = 65.0 g

                                   15.0 g solute
Weight Percent  =  -------------------------  x  100%

Aliphatic compounds, on the other hand, are organic substances whose carbon atoms link with one another in open chains, either straight or branched, as opposed to containing a benzene ring. Aromatic compounds are organic substances with a planar unsaturated ring of atoms that is stabilized by an interaction of the bonds forming the ring. As a result, the primary distinction between aromatic and aliphatic chemicals is that aromatic compounds lack a cyclic structure while aliphatic compounds have straight, branching, or cyclic structures.

The volume in milliliter of 7.44 g of acetone 9.4897 mL

It is necessary to understand a substance's mass, volume, and density in order to answer this question. By dividing a material's mass by volume, the density of the substance may be calculated. The equation for density may now be written in mathematical form using the expression for density, and the equation for mass can be produced by rearrangement using the equation for density as a starting point.

Mass of acetone = 7.44 g (given)

Volume of acetone (v) =  mass of acetone ÷ density of acetone

V = 7.44 g ÷ 0.784 g/mL

V = 9.4897 mL
