WILL GIVE BRANLIEST TO FIRST ANSWER!!! I know the correct answer is either a or d. Can anyone explain which one it is and why? CH3C ≡ CCH2CH2Cl is named: a. 1-chloro-3-pentyne b. 5-chloro-2-pentene c. 1-acetylenyl-3-chloropropane d. 5-chloro-2-pentyne

Answers

Answer 1

Answer: The IUPAC name of [tex]CH_3C\equiv CCH_2CH_2Cl[/tex] is 5-chloro-2-pentyne

Explanation:

1. First select the longest possible carbon chain.  For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.

2. The longest possible carbon chain should contain all the bonds and functional groups.

3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.

4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.

Thus the IUPAC name of [tex]CH_3C\equiv CCH_2CH_2Cl[/tex] is 5-chloro-2-pentyne

C. Radiation warming is blocked by the flip-flops.
O D. Thermal conduction is blocked by the flip-flops.

Answers

Answer:

D. Thermal conduction is blocked by the flip-flops.

Explanation:

Convection is a process of heat transfer which involves fluids( liquid or gas). This however rules convection out of the answer.

Radiation involves heat transfer from the sun to bodies on earth.

Conduction involves heat transfer between two solid bodies. Hot beach sand and flip-flops are solid bodies which validates thermal(heat) conduction.

What is the half-life of a radioisotope if a 50-g sample becomes 25 g after 18
days?
O A. 25 days
O B. 9 days
O C. 50 days
O D. 18 days

Answers

Answer:

18 DAYS IS THE HALF LIFE OF THE RADIOISOTOPE.

Explanation:

Using the formula

Nt = No * (1/2)^t/t1/2

where;

Nt = amount remaining = 25 g

No = Initial amounrt of the radioisotope = 50 g

t = time elapsed = 18 days

t1/2 = half life = unknown

Substitute the values into the equation and obtain the half life of the radioisotope;

Nt = No * (1/2) ^t/t1/2

25 = 50 * (1/2) ^18/t1/2

25 /50 =  (1/2)^18/ t1/2

1/2 = (1/2)^18/t1/2

1/2)^1 = (1/2)^18/t1/2

1 = 18/t1/2

t1/2 = 18 days.

So therefore the half life of the radioisotope is 18 days.

How many moles are there in 500cm3 of a 0.5mol/dm³ solution of sulfuric acid?

Answers

Answer:

0.25moles

Explanation:

There are 1000[tex]cm^{3}[/tex] for 1[tex]dm^{3}[/tex]

Therefore in 1000[tex]cm^{3}[/tex] of 0.5 mol/[tex]dm^{3}[/tex] solution has = 0.5 moles

Therefore 500[tex]cm^{3}[/tex] contains = 0.5/1000 x 500 = 0.25moles

The number of moles of sulfuric acid in 0.5 mol/dm³ solution is equal to 0.25 mol.

What is the molarity?

The concentration of the solution can be determined as the number of moles of a solute in per unit volume of a solution is known as molarity or molar concentration.

The Molarity of the solution is calculated in the following formula:

Molarity (M) = Moles (n)/Volume of the Solution (in L)

Now if we have to find the number of moles of solute in the solution, the formula becomes:

Number of moles of solute (n) = Molarity (M) × Volume of the Solution

Given, the concentration of the sulfuric acid solution = 0.5 mol/dm³

The volume of the solution, V = 500 cm³

As we know, 1 dm³ = 10³ cm³, the volume of solution = 0.5 dm³

The number of moles of the sulfuric acid = M × V

= 0.5 × 0.5 = 0.25 mol

Therefore, 0.25 moles of sulfuric acid in 500cm3 of a 0.5mol/dm³ solution of sulfuric acid.

Ethyl acetate is a sweet-smelling solvent used in varnishes and fingernail polish remover. It is produced industrially by heating acetic acid and ethanol
together in the presence of sulfuric acid, which is added to speed up the
reaction. The ethyl acetate is distilled off as it is formed. The equation for the
process is as follows.

CH3COOH + CH3CH2OH --> CH3COOCH2CH3 + H2O

Determine the percentage yield in the following cases:
a. 68.3 g of ethyl acetate should be produced but only 43.9 g is recovered.
b. 0.0419 mol of ethyl acetate is produced but 0.0722 mol is expected. (Hint:
Percentage yield can also be calculated by dividing the actual yield in moles
by the theoretical yield in moles.)
c. 4.29 mol of ethanol is reacted with excess acetic acid, but only 2.98 mol of
ethyl acetate is produced.
d. A mixture of 0.58 mol ethanol and 0.82 mol acetic acid is reacted and 0.46
mol ethyl acetate is produced. (Hint: What is the limiting reactant?)

Answers

Answer:

The percentage yields are as follows :

a) 64.28%

b) 58.03%

c) 69.46%

d) 79.31%

Explanation:

The percentage yield is the ratio of the actual yield of a product to the expected or theoretical yield expressed as a percentage.

Percent yield = actual yield/theoretical yield x 100%

a) from the question, expected yield is 68.3 g whilst the actual yield is 43.9 g

therefore,

Percentage yield = 43.9 g/68.3 g x 100%

                             =  0.64275 x 100%

                             =  64.28%

b) From the question, expected yield is 0.0722 mol while the actual yield is 0.0419 mol. Therefore

Percentage yield = 0.0419 /0.0722 x 100%

                             = 0.58033 x 100%

                             = 58.03%

c) A limiting reactant is the reactant is is completely used in a recation to form a product. That is, it is the reactant that is not in excess.

From the equation of the reaction :

CH3COOH + CH3CH2OH --> CH3COOCH2CH3 + H2O

1 mole of ethanol reacts with 1 mole of acetic acid to give 1 mole of ethyl acetate.

From the question, ethanol is the limiting reactant because it is not in excess. Hence,

4.29 mole of ethanol should produce 4.29 mole of ethyl acetate (expected yield).

However only 2.98 mol of ethyl acetate is produced (actual yield)

Percentage yield = 2.98mol/4.29 mol x 100%

                            =  0.69463 x 100%

                            = 69.46%

d) From the question, acetic acid is in excess hence ethanol is the limiting reactant

therefore from the equation of the reaction:

1 mole of ethanol reacts with 1 mole of acetic acid to give 1 mole of ethyl acetate.

0,58 mol of ethanol should produce 0.58 mol of ethyl acetate (expected yield)

But 0.46 mol of ethyl acetae was produced (actual yield)

Percentage yield = 0.46mol /0.58 mol x 100%

                             = 0.79310 x 100%

                              = 79.31%

Answers

Answer:

E

Explanation:

A combination reaction is one in which two elements or two compounds react to give a new single compound

Hence, what we are expecting on the reactant side is only a single product and not a mixture of products

For the first reaction, we had two elements giving a single product

For the second reaction, we had same

For the third, we had same

For the fourth, we had two compounds reacting to give a singe new product

While in the last, we had two different products which means it does not follow the definition of a combination reaction and that makes it our answer

What is Melting?Melting, also known as fusion, is a physical process that causes a substance's phase transition from solid to liquid. This happens when the internal energy of a solid increases, typically through the application of heat or pressure, which raises the temperature of the substance to the melting point. Melting is the transformation of a solid into a liquid caused by the application of heat. In a pure crystalline solid, this process occurs at a fixed temperature known as the melting point; an impure solid usually melts over a range of temperatures below the melting point of the principal component.The melting point of a solid is the temperature at which melting occurs. In this process, heat is released from the solid.
