In the free radical chlorination of methylcyclopentane, what is the total number of distinct monochlorinated compounds, including stereoisomers, that would be formed?
A) 4
B) 6
C) 8
D) 10

Answer:

63.53% yield

Explanation:

The balanced equation for this reaction is 2NaCl + H2O -> 2NaOH +Cl2

First we must find the limiting reactant

From NaCl we can only produce 6.06 grams of Cl2 in theory

From H20 we can only produce 38.995 grams in theory

so we know NaCl is the limiting

% yield is (Actual/Theoretical) x100 so

(3.85/6.06)x100= 63.53% yield

Answer:

Ionization

Explanation:

Molecular compounds are chemical compounds composed of discrete molecules. A molecular compound undergoes ionization when being dissolved in water and the formation of ions are being produced. For example, hydrogen chloride is a molecular compound, when it dissolves in water, ionization is being carried out, and ions are being formed.

Answer:

Charles's law

Explanation:

The chemical equation given is that of Charles's law;

  The law states that "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant"

      mathematically;

              v ∝  T ( P, n constant)

So;

        V1/T1 = V2/T2

V and T are volume and temperature values

1 and 2 are initial and final states

Answer:

17 protons, 20 neutrons, and 17 electrons​.

Explanation:

A periodic table can be defined as the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.

Generally, a proper representation of the mass number and atomic number of chemical elements is key and very important in chemistry.

Furthermore, as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton).

The mass number of this neutral atom of Cl-37 is 37 and we know that the atomic number (number of protons) of chlorine is 17. Also, the atomic number of an element is equal to the number of its electrons.

A neutral atom of Cl-37 has 17 protons, 20 neutrons, and 17 electrons.

Hence, a neutral atom of Cl-37 can be identified based on its number of protons because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.

Answer:

V = 22.41 L

Explanation:

Given data:

Mass of nitrogen = 14.0 g

Volume of gas at STP = ?

Gas constant = 0.0821 atm.L/mol.K

Solution:

Number of moles of gas:

Number of moles = mass/molar mass

Number of moles= 14 g/ 14 g/mol

Number of moles = 1 mol

Volume of gas:

PV = nRT

1 atm × V = 1 mol × 0.0821 atm.L/mol.K  × 273 K

V = 22.41 atm.L / 1 atm

V = 22.41 L

Answer:

0.1 dm³.

Explanation:

To obtain the value of 100 cm³ in dm³, do the following:

Recall:

1 cm³ = 0.001 dm³

Therefore,

100 cm³ = 100 cm³ × 0.001 dm³ / 1 cm³

100 cm³ = 0.1 dm³

Thus, 100 cm³ is equivalent to 0.1 dm³.

Answer:

1.67 moles

Explanation:

From the balanced equation of reaction:

                     [tex]SO_2 + 2H_2S -> 3S + 2H_2O[/tex]

1 mole of sulfur dioxide, SO2, is required to produce 3 moles of sulfur, S.

If 1 mole SO2 = 3 moles S, then, how many moles of SO2 would be required for 5 moles S?

     Moles of SO2 needed = 5 x 1/3

                   = 5/3 or 1.67 moles

Hence, 1.67 moles of SO2 would be required to produce 5.0 moles of S.

Answer: 1.7

Explanation:

Answer:

1.99grams

Explanation:

- First, we need to calculate the molar mass of the compound: Ca(HCO3)2

Ca = 40g/mol, H = 1g/mol, C = 12g/mol, O = 16g/mol

Hence, Ca(HCO3)2

= 40 + {1 + 12 + 16(3)}2

= 40 + {13 + 48}2

= 40 + {61}2

= 40 + 122

= 162g/mol

Molar mass of Ca(HCO3)2 = 162g/mol

- Next, we calculate the mass of oxygen in one mole of the compound, Ca(HCO3)2.

Oxygen = {16(3)}2

= 48 × 2

= 96g of Oxygen

- Next, we calculate the percentage composition of oxygen by mass by dividing the mass of oxygen in the compound by the molar mass of the compound i.e.

% composition of O = 96/162 × 100

= 0.5926 × 100

= 59.26%.

- The number of moles of the compound, Ca(HCO3)2, must be converted to mass by using the formula; mole = mass/molar mass

0.0207 = mass/162

Mass = 162 × 0.0207

Mass = 3.353grams

However, in every gram of Ca(HCO3)2, there is 0.5926 g of oxygen

Hence, in 3.353grams of Ca(HCO3)2, there will be;

0.5926 × 3.353

= 1.986

= 1.99grams.

Therefore, there is 1.99grams of Oxygen in 0.0207 moles (3.353g) of Ca(HCO3)2.

Answer:

1.08 g of water

Explanation:

The balanced chemical equation for the reaction of combustion of methane (CH₄) is the following:

CH₄(g) + 2 O₂(g) → CO₂(g) + 2 H₂O(g)

According to the equation, 1 mol of CH₄ reacts with 2 moles of O₂. We convert from mol to grams by using the molar masses:

1 mol CH₄ = (1 x 12 g/mol) + (4 x 1 g/mol) = 16 g

2 mol O₂ = 2 x (2 x 16 g/mol) = 64 g

2 mol H₂O = 2 x ((2 x 1 g/mol) + 16 g/mol)= 36 g

From the masses of reactants (CH₄ and O₂), we can see that the stoichiometric ratio is 64 g O₂/16 g CH₄ = 4.

First, we have to identify which reactant is the limiting reactant. We can compare the stoichiometric ratio with the actual reactants ratio (the masses of reactants we have):

1.92 g O₂/0.80 g CH₄ = 2.4

As 4>2.4, we can conclude that O₂ is the limiting reactant.

Now, we consider the stoichiometric ratio between the limiting reactant (64 g O₂) and the product we have to calculate (36 g H₂O), and we multiply the ratio by the actual mass of O₂:

1.92 g O₂ x 36 g H₂O/64 g O₂ = 1.08 g

Therefore, 1.08 g of H₂O will be produced by the chemical reaction of 0.80 g of methane with 1.92 g of oxygen.

The specific heat of the metal : 0.384 J/g° C,

and a metal with a specific heat of 0.384 is copper

The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released  

Q in = Q out  

Q lost(metal) = Q gained(water)

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

[tex]\tt Q~metal=Q~water\\\\8.5\times c\times (100-23.2)=50\times 4.18\times(23.2-22)\\\\652.8\times c=250.8\Rightarrow c=\dfrac{250.8}{652.8}=0.384~J/g^oC[/tex]

Answer:

Zn, Cu, Fe, Mn, Co, Mo

Explanation:

Biogenic elements are chemical elements constantly present in organisms and having definite biological significance(Bowen, 1966).

There are many of these biogenic elements in nature. Among the elements of the d-block, Zn, Cu, Fe, Mn, Co, Mo are worthy of mention among others.

Free ions of d- block metals are not found in the body. The elements are present in the form of bioinorganic  complexes of the respective metals. They commonly exist as co-factors of proteins that carry out essential biological functions.

Answer:

I

Explanation:

The complete question can be seen in the image attached.

We need to understand what is actually going on here. In the first step that yields product A, the sodamide in liquid ammonia attacks the alkyne and abstracts the acidic hydrogen of the alkyne. The second step is a nucleophilic attack of the C6H5C≡C^- on the alkyl halide to yield product B (C6H5C≡C-CH3CH2).

Partial reduction of B using the Lindlar catalyst leads to syn addition of hydrogen to yield structure I as the product C.

In the given question, the sulphuric acid which is needed to be produced is 408.333 Litres. NaCl + H₂SO₄ → HCl + NaHSO₄

This question is based on stoichiometry, in which we first balance the equation, equate the moles or the masses of elements and using the mole ratio or mass ratio, find the given amount of weight or moles of the desired element from the reaction. Stoichiometry helps us to predict the reaction components that how much it participates in the reaction, how much we the get the product or how much reactant is left. So, in the given question,
Equating the Molar masses: 58 + 98 → 36 + 120. Mass of HCl =[tex]500*0.8= 400[/tex] kg. Balancing the mass:

[tex]400[(58/120)+(98/120)][/tex] → [tex]400[(36/120)+(120/120)][/tex]

Volume of H₂SO₄ 80% = [tex]400 * (98/120)] /0.8= 408.333[/tex]

The final answer is 408.333 Litres. This was solved using Stoichiometry.
