The correct IUPAC name for the following molecule is: _________
a) trans-2,3-dichloro-5-methyl-2-hexene
b) trans-2,3-dichloro-5-methyl-3-hexene cis-2,3-dichloro-5-methyl-3-hexene
c) trans-4,5-dichloro-2-methyl-4-hexene cis-4,5-dichloro-2-methyl-4-hexene
Answers
Answer:
A.) trans-2,3-dichloro-5-methyl-2-hexene
Explanation:
The proposed question and structure has been attached to this answer.
The cis- and trans- isomers are used to denote the alignment of the functional groups to the carbon chain side. From the diagram, we see that:
the two chloro groups on the main compound are in opposite directions (-trans), and not the same sides (-cis)The bottom extended methyl group is on the 5th carbon as we count from left to rightthere's a total of 6 carbon atoms with 1 double bond on the second to third carbon.Hence the name trans-2,3-dichloro-5-methyl-2-hexene
How many atoms of carbon are present in the products?
6CO2+6H2O=C6H12O6+6O2
Answers
Answer:
2.41 * 10^24 atoms of carbon present in the products.
Explanation:
First, we need to find the moles of carbon in the products in order to find the number of atoms.
We see that in the chemical formula, carbon belongs to the compound known as glucose. To get the amount of moles of carbon, we need to divide my the amount of carbon within glucose (in grams) from the total amu ( or grams) of glucose to get the moles.
C6 = 72.066.
C6H12O6 = 180.156
72.066/180.156 = 0.4000199827 moles of Carbon within the Glucose compound
Now we will convert to atoms/molecules by multiplying the moles by avogadro's number..
0.4000199827 moles C * 6.022*[tex]10^{23}[/tex] = 2.408920336 *[tex]10^{24}[/tex] atoms of Carbon present in the products
*Note --> this can be estimated to 2.41 * [tex]10^{24}[/tex] atoms of Carbon

What mass of dinitrogen monoxide, N2O, contains the same number of molecules as 3.00 g of trichlorofluoromethane, CCl3F?
Answers
Answer:
0.9612 g
Explanation:
First we calculate how many moles are there in 3.00 g of CCl₃F, using its molar mass:
3.00 g CCl₃F ÷ 137.37 g/mol = 0.0218 mol CCl₃FNow, we need to calculate how many grams of N₂O would have that same number of molecules, or in other words, the same amount of moles.
Thus we calculate how many grams would 0.0218 moles of N₂O weigh, using the molar mass of N₂O :
0.0218 mol N₂O * 44.013 g/mol = 0.9612 g N₂OThe mass of dinitrogen monoxide is 0.9612 g
The calculation is as follows:The number of moles are there in 3.00 g of CCl₃F, using its molar mass:
= 3.00 g CCl₃F ÷ 137.37 g/mol
= 0.0218 mol CCl₃F
Now the mass should be
=[ 0.0218 mol N₂O × 44.013 g/mol
= 0.9612 g N₂O

A 12.0% sucrose solution by mass has a density of 1.05 gem, what mass of sucrose is present in a 32.0-mL sample of this solution?
A) 0.126g
B) 3.66g
C) 4.03g
D) 3.84g
E) 280 g
Answers
Answer:
Option C. 4.03 g
Explanation:
Firstly we analyse data.
12 % by mass, is a sort of concentration. It indicates that in 100 g of SOLUTION, we have 12 g of SOLUTE.
Density is the data that indicates grams of solution in volume of solution.
We need to determine, the volume of solution for the concentration
Density = mass / volume
1.05 g/mL = 100 g / volume
Volume = 100 g / 1.05 g/mL → 95.24 mL
Therefore our 12 g of solute are contained in 95.24 mL
Let's finish this by a rule of three.
95.24 mL contain 12 g of sucrose
Our sample of 32 mL may contain ( 32 . 12) / 95.24 = 4.03 g
A candle made of certain wax blend burns at a rate of 44.2 mg/min. What is the value of this burn rate if expressed in grams/hour
Answers
Answer:
2.652 g/h.
Explanation:
Burn rate (in mg/min) = 44.2 mg/min
Burn rate (in m/h) =?
We'll begin by converting 44.2 mg/min to g/min. This can be obtained as follow:
1 mg/min = 0.001 g/min
Therefore,
44.2 mg/min = 44.2 mg/min × 0.001 g/min / 1 mg/min
44.2 mg/min = 0.0442 g/min
Finally, we shall convert 0.0442 g/min to g/h. This can be obtained as follow:
1 g/min = 60 g/h
Therefore,
0.0442 g/min = 0.0442 g/min × 60 g/h / 1 g/min
0.0442 g/min = 2.652 g/h
Therefore, 44.2 mg/min is equivalent to 2.652 g/h.
Thus, the burn rate (in m/h) is 2.652 g/h.
If 18.00 mL of 0.1000 M magnesium hydroxide reacts with 10.00 mL of hydrochloric acid, what is the molarity of the acid solution?
Answers
Answer:
0.36M HCl
Explanation:
The reaction of Mg(OH)₂ with HCl is:
Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O
Where 1 mole of magnesium hydroxide reacts with 2 moles of HCl
To solve this question, we need to find the moles of Mg(OH)₂ that reacted and, with chemical equation, solve for the moles of HCl and its molarity (Using the 10.00mL = 0.01000L) as follows:
Moles of Mg(OH)₂:
18mL = 0.018L * (0.100mol / L) = 0.0018 moles Mg(OH)₂
Moles HCl:
0.0018 moles Mg(OH)₂ * (2 moles HCl / mol Mg(OH)₂) = 0.0036 moles HCl
Molarity HCl:
0.0036 moles HCl / 0.0100L =

Answers
Answer:
253.5mL of Ba(OH)₂ are required to neutralize the HCl solution
The pH at equivalence point is = 7
Explanation:
The reaction of Ba(OH)₂ with HCl is:
Ba(OH)₂ + 2HCl → BaCl₂ + 2H₂O
First, we need to find moles of HCl. With these moles and the chemical equation we can find the moles of Ba(OH)₂ and the volume required:
Moles HCl:
75.0mL = 0.075L * (0.845mol / 1L) = 0.063375moles HCl
Moles Ba(OH)₂:
0.06338moles HCl * (1mol Ba(OH)₂ / 2mol HCl) = 0.03169 moles Ba(OH)₂
Volume of the 0.125M Ba(OH)₂:
0.03169 moles Ba(OH)₂ * (1L / 0.125mol) = 0.2535L are required =
253.5mL of Ba(OH)₂ are required to neutralize the HCl solution
As the titration was of a strong acid, HCl, with a strong base, Ba(OH)₂, the pH at equivalence point is = 7

Use the activity series to determine if the following will react.
HCI + Zn —>
State whether they will or won't react and explain your reasoning.
Answers
Answer:
1. They will react.
2. 2HCI + Zn —> ZnCl2 + H2
Explanation:
1. From the question given above,
We can see that Zn is higher than H in the activity series.
NOTE: Elements higher (i.e at the top) in the activity series will displace those lower (i.e at the bottom) in the series. Thus, Zn is higher in the series than H. Therefore, Zn will displace H from solution. Hence, they will react.
2. The product obtained from the reaction can be seen as follow:
HCI + Zn —> ZnCl2 + H2
The above equation can be balance as follow:
There are 2 atoms of H on the right side and 1 atom on the left side. It can be balance by putting 2 in front of HCl as shown below:
2HCI + Zn —> ZnCl2 + H2

The type of bond is determined by the difference in electronegativity of the atoms. Hence, option D is correct.
What is a bond?A chemical bond is what holds atoms together in molecules.
The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity. The difference in electronegativity between two atoms determines how polar a bond will be.

Answers
Answer:
Heat the molecule
Explanation:
Since most bonds require energy to form, they also give off energy when they are broken. But before most bonds break, the molecule has to be heated. Then the atoms start to move, and when they move too much, the bond breaks. Molecules that require less energy to break than they give off when broken are called fuels.

If 6.63 g of CuNO3 is dissolved in water to make a 0.140 M solution, what is the volume of the solution in milliliters?
Answers
Answer:
377mL is the volume of the solution
Explanation:
A 0.140M solution of CuNO₃ contains 0.140 moles of CuNO₃ per liter of solution. Thus, we need to convert first the mass of CuNO₃ to moles using its molar mass and, with the moles available, we can find the volume of the solution, thus:
Moles CuNO₃ -Molar mass: 125.55g/mol:
6.63g * (1mol / 125.55g) = 0.0528 moles of CuNO₃.
Volume of solution:
0.0528 moles of CuNO₃ * (1L / 0.140 moles CuNO₃) = 0.377L

Predict the molecular structure (including bond angles) for each of the following.
a. PCl3
b. SCl2
c. SiF4
Answers
Answer:
PCl3 - trigonal pyramidal <109 degrees
SCl2 - bent<109 degrees
SiF4 - tetrahedral 109 degrees
Explanation:
The shape of all three molecules derive from a tetrahedral arrangement of electron pairs.
However, in PCl3 there is a lone pair of electrons on P and three bond pairs. This leads to the observance of a trigonal pyramidal geometry with bond angle <109 degrees.
In SCl2, there are four regions of electron density around S, two lone pairs and two bond pairs leading to a bent molecular geometry with bond angle <109 degrees.
In SiF4, there are four bond pairs and no lone pair. The molecular geometry is tetrahedral with a bond angle of 109 degrees.
what is the molarity of a solution made by adding 0.720 mole of NaOH to 2.40 liters of water
Answers
Answer:
Molarity = 0.3 M
Explanation:
Given data:
Moles of NaOH = 0.720 mol
Volume of water = 2.40 L
Molarity = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Molarity = 0.720 mol / 2.40 L
Molarity = 0.3 mol/L
Molarity = 0.3 M
