Answer:
4-ethyl-6-methyl-3-heptene
Explanation:
Longest chain is seven long so it is heptane
But there is a double bond, so that becomes heptene
The double bound starts on the third carbon, so it is 3-heptene (this tells us where the double bond is)
Now we just got to do the substituents!
There is a ethyl group of the fourth carbon and then a methyl group on the sixth!
Ergo, 4-ethyl-6-methyl-3-heptene

Suppose that you experimentally determine the molar extinction coefficient (ε) of a complex ion sample to be 8171 L/mol-cm at 510 nm. The literature value for the ε of the complex ion sample is reported as 8400 L/mol-cm. What is the percent purity of your experimental sample
Answers
The percent purity of your experimental sample is 97.3 %
The percentage purity % = impure value/pure value × 100 %.
Actual value of molar extinction coefficient = impure value = 8171 L/mol-cm, pure value = literature value = 8400 L/mol-cm.
Substituting the values of the variables into the equation, we have
% purity = 8171 L/mol-cm/8400 L/mol-cm × 100 %
% purity = 0.9727 × 100 %
% purity = 97.27 %
% purity ≅ 97.3 %
The percent purity of your experimental sample is 97.3 %

balance CHCl3 + O2 = CO2 + H2O + Cl2
Answers
Answer:
2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2
Explanation:
Left Hand Side(LHS)
We have CHCl3 and O2
Right Hand Side(RHS)
We have CO2, H2O and Cl2
Balancing
To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2
H2O remains the same
Before CO2 put 2 giving 2CO2
To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)
Combining all;
2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Cations are always _____ than the parent atom and anions are always _____ than the parent atom.
Answers
Answer: smaller, larger
Explanation:
Cations are always {smaller} than the parent atom. Anions are always {larger} than the parent atom.
Cations are always smaller than the parent atom, and anions are always greater than the parent atom.
What is parent atom ?The term "parent atom" refers to an atom that has not yet undergone any chemical transformation. A parent atom is one that is discovered in its initial state.
Because they contain fewer electrons while maintaining the same nuclear charge, cations are always smaller than their parent atoms. Because the protons in the nucleus are holding the remaining electrons more tightly, their radii are less than those of the parent atoms. In the case of anion, this is the opposite.
Due to variations in electron-electron repulsion, the ionic radii of cations and anions are always less or bigger than the parent atom, respectively. The trends in ionic radius follow those in atomic size.
Thus, Cations are always smaller than the parent atom, and anions are always greater than the parent atom.

Answers
Based on the balanced equation, the mole ratio of Iron to Sulphur is 8 to 1.
This means that for every mole of sulfur, 8 moles of iron is needed for the reaction.
∴ since the moles of Sulfur = 8.49 moles
⇒ moles of Iron = 8.49 moles × 8
= 67.92 moles

Approximately now much energy will it take to
break all the bonds present in the molecule below?
Answers
Answer:
498 kj/mol
Explanation:
Chemical reactions occur as a result of bond breaking and bond formation.
The bonds in reactants are broken and atoms are rearranged to form new bonds.
During bond breaking energy is absorbed to break the bonds of reactants while bond formation involves the release of energy during the formation of new bonds.
In our case;
In 1 mole of the Oxygen molecule, there is one O=O bond
Energy absorbed to break O=O is 498 kJ/mol
Therefore, the ΔH required to break all the bonds in one mole of Oxygen(O₂) molecules is 498kJ/mol.
Note that, bond breaking is endothermic since energy is absorbed from the surroundings.

Describe how you could adjust the settings of the simulation to increase the number of red (H3O+) and blue (A-) particles in the solution of equilibrium. In three to four sentences, justify your answer and explain how and why this would change the pH of the solution.
Answers
The circumstances that the system is exposed to may be altered in such a way as to cause a change in the chemical equilibrium. When we do this, we are said to be "stressing the balance."
In a chemical process that has reached equilibrium, one method is to either add or remove a product or a reactant. When more of a reactant is introduced, the equilibrium changes to alleviate the pressure, which results in the production of more products.
This is further explained below.
how and why this would change the pH of the solution.?Generally, When more product is introduced, the equilibrium moves away from products and toward reactants in an effort to lower the level of stress.
In the event that either the reactant or the product is withdrawn from the system, the equilibrium changes such that more of the corresponding substance is produced to compensate for the loss.
According to Ch/atelier's Principle, which claims that if a reaction in equilibrium is disturbed, the equilibrium will change to counterbalance that change, this indicates that if a reaction is in equilibrium, the equilibrium will alter to counteract that change.
If a solution has a large number of hydrogen ions, the pH of the solution will be low, and it will be classified as an acidic solution.
In conclusion, On the other hand, a solution is said to have a high pH and be in the basic state if it contains a low quantity of hydrogen ions in its composition.
The ratio of the concentration of hydrogen ions to the concentration of hydroxide ions is negative and inversely proportional.

Sulphuric acid (H2SO4) is titrated against 25.00cm3 of 0.200 mol/dm3 Sodium hydroxide solution (NaOH). It is found that 23.20 cm3 of sulphuric acid is required for neutralization. Calculate the concentration of Sulphuric acid
Answers
Approximately 0.108 mol dm^-3
Explanations,
1. Make the balance chemical equation
2. Convert the 25 cm^3 to 0.025 dm^3 by multiplying 25 with 10^-3 (or 25 / 1000)
3. Concentration is equal to = moles of substance over volume of solution
4. Calculate how many number of moles present in 0.025dm^3 of sulphuric acid.
Mole = concentration x volume
^ rearranged from conc = mole/volume
Mole = 0.200 x 0.025 = 0.005 mol
5. Use the balance chemical equation ad mole ratio. In this case,
H2SO4 + 2NaOH —> 2H2O + Na2(SO4)
Thus the ratio between Sulphuric acid and Sodium Hydroxide is 1:2
Hence, the mole of H2SO4 is 0.005/2 = 0.0025 mol
6. Calculate the concentration of the sulphuric acid by using conc. = mole/volume
Hence the answer is 0.0025/(23.20 x 10^-3) = 0.108 mol dm^-3 rounded off at the 3 Sigfigs

Calculate the change in temperature of a 5.0 g sample of water that loses 1800J of heat energy.
Q = mcΔT
The specific heat of water is 4.18 J/g°C.
Answers
Taking into account the definition of calorimetry, the change in temperature of a 5.0 g sample of water that loses 1800J of heat energy is 86.12 C.
In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body can receive or give up without affecting its molecular structure. If the molecular structure does not change, the state (solid, liquid, gaseous) does not change. Since the molecular structure does not change, a change in temperature is observed.
In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case, you know:
Q= 1800 J c= 4.18 [tex]\frac{J}{gC}[/tex] m= 5 g ΔT= ?Replacing in the expression to calculate heat exchanges:
1800 J= 4.18[tex]\frac{J}{gC}[/tex]× 5 g× ΔT
Solving:
1800 J ÷ (4.18[tex]\frac{J}{gC}[/tex]× 5 g)= ΔT
ΔT= 86.12 C
In summary, the change in temperature of a 5.0 g sample of water that loses 1800J of heat energy is 86.12 C.
