Explanation:

The acid-catalyzed hydration of 1-methylcyclohexene proceeds by an SN1 mechanism. The reaction involves the formation of carbocations.

Two carbocations are formed leading to the major and minor products. The major product is obtained from the tertiary (more stable) carbocation while the minor product is obtained from the secondary (less stable carbocation).

Tertiary alcohols are not oxidized, hence the major product does not undergo oxidation. However, secondary alcohols are oxidized to ketones.

Store the genetic instructions needed to specify traits.

In DNA, the primary function of chromosome is store the genetic instructions needed to specify traits.

DNA is a hereditary material  which is present in human beings as well as all other living organisms.  Every cell which is present in an organism's body has DNA  which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.

Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.

DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule  and a phosphate group. A base, phosphate  sugar are together called as nucleotides.

Answer:

Explanation:

C₆H₁₂O₆       +      60₂     =     6H₂0     +     6CO₂.

1 mole              6 mole

molecular weight of C₆H₁₂O₆ = 180 g

molecular weight of oxygen = 32 g

1 gram of glucose = 1 / 180 = 5.55 x 10⁻³ moles

1 gram of oxygen = 1 / 32 = 31.25 x 10⁻³ moles

1 mole of glucose reacts with 6 moles of oxygen

5.55 x 10⁻³ moles of glucose will react with 6 x 5.55 x 10⁻³ moles of oxygen

= 33.30 x 10⁻³ moles of oxygen .

But oxygen available = 31.25 x 10⁻³ moles

So available oxygen is less than required .

Hence oxygen is the limiting reagent .

Answer:

V2= 1.03L

Explanation:

Start off with what you are given.

V^1: 1.00L

T^1: 23°C

V^2?

T^2: 33°C

If you know your gas laws, you have to utilise a certain gas law called Charles' Law:

V^1/T^1 = V^2/T^2

Remember to convert Celsius values to Kelvin whenever you are dealing with gas problems. This can be done by adding 273 to whatever value in Celsius you have.

(23+273 = 296)     (33+273 = 306)

Multiply crisscross

1.00/296= V^2/306

296V^2 = 306

Dividing both sides by 296 to isolate V2, we get

306/296 = 1.0337837837837837837837837837838

V2= 1.03L

Answer:

The correct answer is - anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

Explanation:

Anhydrous aluminum chloride is a covalent compound and we know that covalent compounds have less or no polarity. Organic compounds or solvents are mostly non-polar in nature. And it is a thumb rule that like-dissolves-like.

Thus they dissolve covalent molecules like anhydrous aluminum chloride.

Anhydrous magnesium chloride is an ionic compound that tends to interact with a polar solvent but not in a non-polar solvent such as organic solvents.

Anhydrous aluminum chloride is fairly soluble in the organic solvent while anhydrous magnesium chloride is insoluble​ because anhydrous aluminum chloride is covalent whereas anhydrous magnesium chloride is ionic.

AlCl3 quite simply accepts electrons from other atoms, in an try and get a full valence shell of eight electrons. It's why it normally behaves as a Lewis acid. In the response under, the Al atom accepts a lone pair of electrons from a Cl atom.

AlCl3 is hygroscopic and has a great affinity for water. Therefore, aluminum chloride dissolves in water partially.

Answer:

51.03g/mol is the molar mass of X

Explanation:

Based on the reaction:

2XI₃ + 3Cl₂X → 2XCl₃ + 3I₂

Where 2 moles of XI₃ reacts to produce 2 moles of XCl₃ -The ratio of reaction is 1:1-

To solve this question we must find the mass of X per mole (This is the atomic mass of X).

As the moles of both compounds are the same:

1.196g / 0.436g = Molar mass XI₃ / molar mass XCl₃ (1)

Also:

Molar mass XI₃ = Molar mass X + 380.71g/mol

Molar mass XCl₃ = Molar mass X + 106.36g/mol

Replacing in (1):

2.7431 = (Molar mass X + 380.71g/mol) / (Molar mass X + 106.36g/mol)

2.7431 Molar mass X + 291.76g/mol = Molar mass X + 380.71g/mol

1.7431 Molar mass X = 88.95g/mol

Molar mass X = 51.03g/mol

Answer:

yes

Explanation:

Yes, size of molecule has greatly affected the gas law.

The gas laws affected depending on whether we use heavy gas particles or light gas particles because the heavy gas particles can't move faster as light gas particles with the increase of temperature.

If the temperature is increased, the gas particles move faster due to absorb of heat energy so they hit the walls of the container. This causes the pressure to rise. The pressure of a gas also increases when the volume of container in which it is placed is decreased. Bigger the molecule size, the stronger the intermolecular forces, so the molecule has higher melting and boiling points so we can conclude that big size molecule greatly affected the gas law.

Explanation:

Without mincing words let's dive straight into the solution to the question.

(a). The freezing point depression can be Determine by subtracting the value of the initial temperature from the final temperature. Therefore;

The freezing point depression = [ 1 - (-3)]° C = 4°C.

(b). The molality can be Determine by using the formula below;

Molality = the number of moles found in the solute/ solvent's weight(kg).

Molality = ( 11.1 / 58) × (1000)/ ( 90.4 - 11.1) = 2.4 M.

(c). The mass of acetone that was in the decanted solution = 11.1 g.

(d). The mass of water that was in the decanted solution = 89.01 g.

(e). 2.4 = x/ 58 × (1000/1000).

x = 2.4 × 58 = 139.2 g.

(f). The molar mass of acetone = (12) + (1 × 3) + 12 + 16 + 12 + (1 x 3) = 58 g/mol.

Answer:

B.) P4

Explanation:

Step 1: Convert 25.0 grams of phosphorus into moles of phosphorous:

25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4

Step 2: Convert 0.202 mol P4 into moles of O2 using their stoichiometric ratios:

0.202 mol P4 x 5 mol O2/1 mol P4 = 1.01 mol O2

Step 3: Convert 1.01 mol O2 into grams of O2:

1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2

Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).

Because the reaction cannot occur without more phosphorous to react with the 17.7 grams of oxygen remaining, P4 is the limiting reactant.

Answer:  B.) P4

Explanation:

        25 g P4 x 1 mol P4/123.90 g P4 = 0.202 mol P4

        0.202 mol P4 x 5 mol O2/1 mol P4 = 1.01 mol O2

        1.01 mol O2 x 31.98 g O2/1 mol O2 = 32.3 g O2

Because 25.0 grams of phosphorous only needs 32.3 grams of oxygen to react, phosphorous will be the limiting reactant, as after the 25.0 grams of phosphorous is used up, there will still be 17.7 grams of oxygen leftover (excess reactant).
