Write the chemical symbols for three different atoms or atomic cations with 11 electrons.

Answers

Three ways to represent atoms or atomic cations with 11 electrons include :

[tex] {Mg}^{ + } \: {Al}^{2 + } \: {Si}^{3 + } [/tex]

Mg = magnesium has 12 electrons in its neutral state, when it loses one electron to attain stability, it's election becomes 11.

Al = Aluminum has 13 electrons in its neutral state, when it donates 2 electron to attain stability, it becomes (13 - 2). = 11

Si = Silicon has 14 electrons on it's neutral state, when it loses 3 electrons to attain stability, we have (14 - 3) = 11

Hence,

[tex]{Mg}^{ + } \: {Al}^{2 + } \: {Si}^{3 + } [/tex]

are atomic cations with 11 electrons.

The 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%

Answers

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).

How can the Swartz process be modified to work for bacteria? Explain.

Answers

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.

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.

Answers

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.

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.

Answers

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.

If a stronger solution of sodium bicarbonate was used in beaker C, would it require more or less hydrochloric acid to neutralize and why?

Answers

Part A; A stronger solution of sodium bicarbonate require more hydrochloric acid will be required

Part A; The reason why more HCl is required is due to the presence of more hydroxyl ions in the solution

The reason arriving at the above responses are as follows;

Part A

Sodium bicarbonate, NaHCO₃, is baking soda = A basic salt; has the capacity to deprotonate water

Hydrochloric acid, HCl = An acid

The reaction between sodium bicarbonate and hydrochloric acid is presented as follows;

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

The equation for the ionic reaction is as follows;

Na⁺(aq) + HCO₃⁻(aq) + H⁺(aq) + Cl⁻(aq) → Na⁺(aq) + Cl⁻(aq) + H₂O(l) + CO₂(g)

In water, we have;

HCO₃⁻(aq) + H₂O(l) ⇄ H₂CO₃(aq) + OH⁻(aq)

The presence of a stronger solution of sodium bicarbonate, will produce more hydroxyl ions, OH⁻(aq), which will require, more HCl to neutralize

Therefore, if a stronger solution of sodium bicarbonate was used, more hydrochloric acid will be required

Part B

The solution of stronger sodium bicarbonate will contain a higher concentration of hydroxyl ions and therefore, require more HCl, to neutralize

what is the source of energy that is absorbed by the electrons to move from the ground state to excited state?

Answers

Answer:

I think an atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

10 advantages of atomic absorption spectrometer over flame photometer

Answers

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.
