How many square centimeters are in an area of 5.90 inch^2 ?
Answer:
38.0644 cm^2
Explanation:
5.90 ×6.451 cm^2The allele for dimples is dominant and the allele for no dimples is recessive. If two parents that are heterozygous for dimples produce a child, what are the chances the child will have dimples? A. 25% B. 50% C. 75% D. 100%
The chances the child will have dimples is 50%. Hence The correct option is (B).
What is Heredity ?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
There is a 50% chance that the child does not obtain the allele needed for dimples (dd), and a 50% chance that the child is heterozygous (Dd). Because dimples is an autosomal dominant trait, heterozygosity will express dimples, leading to a 50% chance that the child will have dimples.
Therefore, The chances the child will have dimples is 50%. Hence The correct option is (B).

Which of the following is a result of increasing the temperature of a system that includes a reaction in the forward direction that is exothermic?
a) The equilibrium constant decreases.
b) The concentrations of the products increase.
c) The equilibrium constant increases.
d) The concentrations of the reactants decrease.
Answer:
I believe the answer your looking for is out of A or B
Explanation:
Option B because if the heat increases its essentially causing the concentration to increase by replacing the weak bonds with stronger ones
In increasing the temperature of a system that includes a reaction in the forward direction that is exothermic, the concentration rises as weak bonds are replaced by stronger ones.
What is the temperature of a system?The average kinetic energy of the atoms or molecules in a system is measured by temperature. No heat is transmitted between two objects in thermal equilibrium, according to the zeroth law of thermodynamics.
In conclusion, as the temperature of the system rises, the concentration rises as weak bonds are replaced by stronger ones.

How does the volume occupied by a cubic centimeter (cm3) compare with the volume occupied by a milliliter
Answer:
One cubic centimeter is equal to one milliliter. Cubic centimeter is used interchangeably with millimeter. Centimeter belongs in the CGS unit system (centimeter-gram-second system) while liter belongs in the SI (Système International d'Unités) unit system. These two are equal.
Explanation:
if 10 moles of A and 7.5 moles of B are taken in a flask, identify the value of moles of A4B3 produced in a reaction.
The number of moles of A4B3 produced in a reaction is obtained by stoichiometry.
The term stoichiometry refers to mass-mole relationship. The first step in solving this problem is by writing the correct reaction equation as follows;
4A + 3B -------> A4B3
If 4 moles of A yields 1 mole of A4B3
10 moles of A yields 10 * 1/4 = 2.5 moles of A4B3
Therefore, 2.5 moles of A4B3 is produced.

Acrylonitrile and ethyl acetate have the same boiling point: 77.2ºC. In one to two sentences, explain what outcome you would expect if a mixture of these two substances were distilled (SHORT ANSWER)
Acrylonitrile and ethyl acetate will be collected together since they both have the same boiling point.
The method of distillation highly depends on the difference between the boiling points of the Acrylonitrile and ethyl acetate.
Since they have the same boiling point, the two substances turn into vapor at the same temperature and are collected simultaneously.
Hence separation is not achieved by distillation.

They would boil at the same rate. Basically meaning, that they would both be finished distilling at the same time.

10 advantages of atomic absorption spectrometer over flame photometer
Answer:
(1) It does not suffer from spectral interference, which occurs in flame emission spectroscopy.
(2) By atomic absorption technique, traces of one element can easily be determined in presence of high concentration of other elements.
The technique makes use of the atomic absorption spectrum of a sample in order to assess the concentration of specific analytes within it. It requires standards with known analyte content to establish the relation between the measured absorbance and the analyte concentration and relies therefore on the Beer–Lambert law.

How can the Swartz process be modified to work for bacteria? Explain.
Answer:
https://swartzbiotechnologylab.sites.stanford.edu/research
Explanation:
Alkyl chlorides and alkyl bromides are typically transformed into alkyl fluorides in the organic reaction known as the Swarts Reaction.
Swartz reaction?Frederick Jean Edmond Swarts first reported this procedure in 1892. Heating the alkyl chloride or alkyl bromide in the presence of heavy metal fluorides like AGF, Hg2F2, CoF2, or SbF3 causes this reaction.
Swartz process can be used to modify work for bacteria. Bacterial biofilms are collections of microorganisms where the cells are immersed in an extracellular polymeric matrix that the bacteria have self-produced.
In contrast to planktonic bacteria, which are in a state of free movement in a bulk solution, this situation is very different.
Applications:
In this process, alkyl fluorides are created.Fluorinated aliphatic organic molecules, or Freons, are produced via a different variation of the same process.Anhydrous hydrogen fluoride is fluorinated to produce Freons in the presence of antimony salts, which exhibit the oxidation states +3 and +5.Therefore, Alkyl chlorides and alkyl bromides are typically transformed into alkyl fluorides in the organic reaction known as the Swarts Reaction.
