Which isomer of 1-bromo-2-tert-butylcyclohexane reacts faster when refluxed with potassium tert-butoxide?Draw the structure of the expected major product from the faster reacting compound.

Answer:

2 pair of an electron

Explanation:

carbon having 6 valence electron 2 electron involved in covalent bonding so 4 electron means 2 pairs of an electron will left.

Answer:

0.54 mole of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2CH3OH + 3O2 —> 2CO2 + 4H2O

From the balanced equation above,

2 moles of CH3OH reacted to produce 4 moles of water.

Finally, we shall determine the number of mole of water (H2O) produced by the reaction of 0.27 moles of CH3OH. This can be obtained as follow:

From the balanced equation above,

2 moles of CH3OH reacted to produce 4 moles of water.

Therefore, 0.27 moles of CH3OH will react to produce = (0.27 × 4)/2 = 0.54 mole of H2O.

Thus, 0.54 mole of H2O is produced from the reaction.

Therefore,

Option C is correct✔

According to the electronic configuration, the atomic number of the element is 18.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

what are tho anwser choices

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

Answer:

The reactants must be in the liquid phase.

Explanation:

Homogeneous means that something is of the same nature.

In the context of catalysis, it means that the catalyst and the reactants are in the same phase.

If the catalyst is in the solid phase, the reactants are solids are well.

If the catalyst is in the liquid phase, then the reactants are also in the liquid phase.

And so on.

Answer:

A) They get oxidized into carbon monoxide and carbon dioxide by the oxygen molecules generated on the electrode.

Explanation:

In the electrolysis of Aluminium, the oxygen reacts with the carbon anodes forming carbon dioxide. That is, the anodes are oxidized. To ensure that the reaction completes, the anode must gradually be replaced as the reaction proceeds. The correct option is hence;

Explanation:

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

The formula of Silver (III) Sulfide is Ag2S3.

Answer: the reliability will be worse

Explanation:

Suppose we used 0.5 M NaOH to titrate our vinegar sample instead of 0.1 M.

Now by using 0.5M instead of 0.1M we are increasing the concentration of NaOH,

We know that  the moles used = Volume x concnetration.

so for the same no of moles, if the concentration increases, the volume decreases.

Hence it will consume less NaOH.

now Since the volume decreases, the titration volume of less number will increase the % error.

Therefore the reliability will be worse.      

The effect that the concentration of the added base has on the reliability of the results of the titration in question is; The reliability will be worse.

We are told that;

0.5 M NaOH is to be used to titrate a vinegar sample instead of 0.1 M.

Now, 0.5 M means a concentration of 0.5 and since it is higher than 0.1M, it means the concentration of NaOH will increase.

Formula for number of moles used is;

n = V × M

Where;

n is number of moles

V is volume

M is concentration

We can see that number of moles is directly proportional to the volume and concentration.

Thus, if the number of moles remains unchanged, as we have increased the concentration, it means that the volume will decrease.

Thus, lesser volume of NaOH will be used and as a result of this decrease in volume, there will be a greater possibility of error.

In conclusion, we can say that the reliability will be worse.

Protons and neutrons have most of the mass but occupy very little of the volume of the atom.

The statement concerning the structure of the atom is correct is Protons and neutrons have most of the mass but occupy very little of the volume of the atom. Therefore, option D is correct.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.

But when it comes to the name atom, we must travel back to 400 B.C. ancient Greece. The Greek word atomos, which meaning "uncuttable," was proposed by Democritus, a renowned philosopher. In the end, all matter could be reduced to distinct, tiny particles, or atomos, he said.

The smallest unit of matter that may be divided without producing electrically charged particles is the atom.

Thus, option D is correct.
