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:

D.

Explanation:

CH₃C≡ CCH₂CH₂Cl

Since there are 5 carbons so the suffix used is "pent"

There is a triple bond so its alkyne

So the compound becomes 2-pentyne (2 because the triple bond is with the 2nd carbon)

Then,

The functional group of chlorine is attached with 5th carbon So the compound becomes

5-chloro,2-pentyne

What is an Isomer ?

Isomers are compounds that contain exactly the same number of atoms, i.e., they have exactly the same empirical formula, but differ from each other by the way in which the atoms are arranged.

By the definition of Isomer we can understand that we have to look for a compound that has same number of Carbon , Hydrogen and Chlorine atoms as that given .

Number of Carbon atoms = 3

Number of Hydrogen atoms = 6

Number of Chlorine atoms = 2

It can be seen that there are same number of Carbon , Hydrogen and Chlorine atoms in the fourth option , so Option 4 is the correct answer.

In a reaction, 25 grams of reactant
AB breaks down into 10 grams of
product A and an unknown amount
of product B. Using the law of conservation of mass, how much does product B weigh?
a. 25 g
B. 10 g
С. It cannot be determined from the given
information.
d
D. 15g

Answers

Answer:

D. 15g

Explanation:

The law of conservation of mass states that, in a chemical reaction, mass can neither be created nor destroyed. This means that the amount of matter in the elements of the reactants must be equal to the amount in the resulting products.

In this question, 25 grams of a reactant AB, was broken down in a reaction to produce 10 grams of products A and X grams of product B. According to the law of conservation of mass, the mass of the reactant must be equal to the total mass of the products. This means that 25 grams must also be the total mass of both products in this reaction. Hence, if product A is 10 grams, product B will be 25 grams - 10 grams = 15 grams.

Therefore, product B must be 15 grams in order to form a total of 25 grams when added to the mass of product A. This will equate the mass of the reactant AB and fulfill the law of conservation of mass.

John Dalton was the chemist that gave the theory of atoms. His atomic model was incorrect as he said that the atoms cannot be further divided, but they are made of smaller particles. Thus, option D is correct.

What is Dalton's atomic model?

Dalton's atomic model stated that all matter is composed of atoms that are made of elements with identical properties and mass. He further stated the formation of the compounds from the molecules.

In the theory, he stated that atoms cannot be divided further and are indivisible. This was proven wrong as the atoms are composed of sub-atomic particles namely, electrons, neutrons, and protons.

Therefore, the statement that atoms are indivisible in Dalton's atomic theory is incorrect.

Reversing the two statements that make up a categorical or implicational statement yields its opposite. Carry on a discussion is more properly referred to as "converse." Let's say there is a conditional statement of the form "If p then q." If q, then p is the converse. In a symbolic sense, q p is the opposite of p q.

Need help please: How many mL of 0.150 Molarity CaBr2 solution must be used to react with 50 mL of 0.115 Molarity AgNO3?

CaBr2 + 2AgNO3 --> Ca(No3)2 + 2AgBr

Answers

Answer:

0.019 L or 19.1 mL

Explanation:

Given the equation of the reaction; we have:

CaBr2 + 2AgNO3 --> Ca(No3)2 + 2AgBr

We must first obtain the number of moles of AgNO3 reacted. This can be obtained from;

Concentration of AgNO3 reacted= 0.115 M

Volume of AgNO3 reacted= 50 ml

Since

Number of moles of AgNO3= concentration of AgNO3 × volume of AgNO3

Number of moles = 0.115 M × 50/1000 = 5.75 ×10^-3 moles

From the reaction equation;

2 moles of AgNO3 reacts with 1 mole of CaBr2

5.75 ×10^-3 moles of AgNO3 reacts with 5.75 ×10^-3 moles × 1 /2 = 2.875×10^-3 moles of CaBr2

Now;

Number of moles of CaBr2= concentration of CaBr2 × volume of CaBr2

Number of moles of CaBr2= 2.875×10^-3 moles

Volume of CaBr2= ????

Concentration of CaBr2= 0.150 M

Hence;

Volume of CaBr2= number of moles of CaBr2/ concentration of CaBr2

Volume of CaBr2= 2.875×10^-3 moles / 0.150

Volume of CaBr2= 0.019 L or 19.1 mL

Answer:

19 mL of CaBr₂ solution should be used to react with AgNO₃

Explanation:

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) react:

AgNO₃: 2 molesCaBr₂: 1 mole

50 ml of 0.115 M AgNO₃ react. Since molarity is the number of moles of solute per liter of solution, then you can do the following rule of three: if there are 0.115 moles of AgNO₃ in 1 L, in 0.05 L (being 1 L = 1000 mL, then 50 mL = 0.05 L How many moles are there?

[tex]moles of AgNO_{3}=\frac{0.05L*0.115 moles}{1 L}[/tex]

moles of AgNO₃=5.75*10⁻³

Now we can make a new rule of three to calculate the amount of moles necessary for CaBr₂ to react with moles of AgNO₂: if stoichiometry 2 moles of AgNO₃ react with 1 mole of CaBr₂, 5.75*10⁻³ moles of AgNO₃ with how many moles of CaBr₂ react ?

[tex]moles of CaBr_{2} =\frac{5.75*10^{-3}moles of AgNO_{3}*1 mole of CaBr_{2} }{2moles of AgNO_{3}}[/tex]

moles of CaBr₂=2.875*10⁻³ moles

Being 0.150 the molarity of the CaBr₂ compound, you can apply the following rule of three: if by definition of molarity 0.150 moles are in 1 L, 2.875 * 10⁻³ moles in how much volume is it present?

[tex]volume=\frac{2.875*10^{-3} moles*1L}{0.150 moles}[/tex]

volume=0.019 L

Being 1 L = 1000 mL, then 0.019 L = 19 mL

19 mL of CaBr₂ solution should be used to react with AgNO₃

How much quantity in mL of concentrated 12 M hcl (aq) is needed to prepare a 250mL of 0.5 M hcl solution?

Answers

Answer:

10.41 mL of concentrated 12 M HCl (aq) is needed to prepare a 250mL of 0.5 M HCl solution

Explanation:

Dilution is the procedure to prepare a less concentrated solution from a more concentrated one. The amount of solute does not vary, but the volume of the solvent varies. More solvent is added and the concentration of the solute decreases, as the volume of the solution increases.

In this case it is fulfilled:

Vi * Ci = Vf * Cf

Vi = initial volume

Ci = initial concentration

Vf = final volume

Cf = final concentration

Being:

Vi=?Ci= 12 MVf= 250 mL= 0.250 L (being 1 L= 1000 mL)Cf= 0.5 M

Replacing:

Vi*12 M= 0.250 L* 0.5 M

Solving:

[tex]Vi=\frac{0.250 L*0.5 M}{12 M}[/tex]

Vi= 0.01041 L= 10.41 mL

10.41 mL of concentrated 12 M HCl (aq) is needed to prepare a 250mL of 0.5 M HCl solution

How many grams of LiNO2 are required to make 250 mL of 0.75 Molarity solution?

Answers

Answer:

159 g OF LiNO2 WILL BE USED TO MAKE 0.25 L OF 0.75 M SOLUTION.

Explanation:

How many grams of LiNO2 are required to make 250 mL of 0.75 M?

First calculate the molarity in mol per dm3

0.75 M of LiNO2 reacts in 250 mL = 250 /1000 L volume

0.75 M = 0.25 L

In 1 L, the molarity of LiNO2 will be:

= (0.75 * 1/ 0.25) M

= 3 mol/dm3 of LiNO2

Next is to calculate the molarity in g/dm3:

Molarity in mol/dm3 = molarity in g/dm3 / RMM.

RMM of LiNO2

(Li = 7 , N =14 , 0 = 16)

RMM = ( 7 + 14 + 16 * 2) = 53 g/mol

Molarity in mol/dm3 =  Molarity in g/dm3 / RMM

Molarity in g/dm3 = Molarity in mol/dm3 * RMM

Molarity in g/dm3 = 3 * 53

Molarity in g/dm3 = 159 g/dm3.

So therefore, to make 250 mL of 0.75 M of LiNO2, we use 159 grams of LiO2.
