Explanation:

The bond formed between two atoms each sharing one electron is called single covalent bond

The figure 1 is the structure of diamond. The type of bond in diamond is covalent sp³ bond. DIamond exists in hexagonal arrangement of carbon atoms.

Allotropes are substances formed from a single elements with different number in various size and shape. Carbon exhibit catenation property which means it can forms chains with other carbon in any large number.

The allotropes of carbon are diamond, graphene and fullerene. Diamond is hexagonal arrangement of carbons atom bonded covalently in sp³ hybridisation.

In graphene as shown in the second figure, bonded carbons atoms are arranged as layers where carbon is in sp²hybridisation. In the case of fullerenes, there are both hexagonal and pentagonal rings adjacent to each and are formed by 60-70 carbons.

In all these allotropes, the bond type between two carbons atoms is covalent. Covalent bond is formed by sharing of electrons between the two atoms.

Answer:

1dm = 10cm

1dm3 = 10cm x 10cm x 10cm = 1000cm3

1L = 1000cm3

so 1litre = 1dm3

4 moles in 2 dm3

1L = 1000cm

0.3 moles in 200cm3 =

Answer:

If in volume of 10.0L it is 25°C than it will be 37.5C volume in the new temperature if increased from 10.0L to 15.0L

Explanation:

10.0L=25°C

15.0L=?

10×2.5= 25

15×2.5=37.5

Kelvin(K)= C+273=T

=37.5+275=312.5

=C=312.5-275

Answer:

The law of constant proportion states that the percentage of each compound will stay constant regardless of the source size.

In other words, since 11.19% + 88.81% = 100%, in a 100 gram sample, these percentages will stay the same. In this case, 100% is "equal" to 100 grams.

So, 11.19 grams hydrogen and 88.81 grams oxygen will be present in a 100 gram sample of pure water.

Answer:

Here down below is the equation

Explanation:

Iron (III) chloride can be produced by the reaction shown in this equation:

2Fe +3C2 (arrow) 2FeCl3

Calculate the maximum mass of Iron (III) chloride that can be produced from 11.20 grams of iron?

Relative atomic masses: Cl= 35.5 , Fe =56

The maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.

Mass can be defined as inertia is a quantitative measure of a fundamental feature of all stuff.

It can also be defined as weight is defined as the force exerted by an item while mass is defined as the amount of matter in an object.

The SI unit of mass is kilogram or gram.

Mass can be expressed as

Mass =  Given mass of substance / Formula mass

Mass of substance = 11.20 g

Formula mass of FeCl₃ = 162.2

So, mass = 11.20 g / 162.2 g

               = 0.069 grams

Thus, the maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.

The ΔH fusion used to calculate the energy released when a mass of liquid freezes by using the formula Grams liquid x mol/g x ΔH fusion.

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

Heat of formation or enthalpy is given for any one mole of substance.

And it will be calculated for moles of gases as, so for this first mass will be converted into moles as-

n = W/M, where

W = given mass in grams

M = molar mass in g/mol

and then multiply the given moles by the enthalpy of formation of one mole.

Hence, Grams liquid x mol/g x ΔH fusion is used.

Answer:

It may leave some chemicals such as herbicides and pesticides in the water

Explanation:

i just took the test

Distillation may leave some chemicals such as herbicides and pesticides in the water. Therefore, option D is correct.

By using selective boiling and condensation, distillation, also known as traditional distillation, is the process of removing the constituents or compounds from a liquid mixture. The process of heating solid materials to create gaseous products is known as dry distillation.

A chemical is purified through distillation by being separated from a non-volatile or less-volatile substance. Because various compounds frequently have different boiling points, when a mixture is distilled, the components frequently separate from the mixture.

Among the many industrial uses of distillation are the production of alcoholic drinks, water purification, and oil refining. Distillation is a physical procedure that removes desired pure compounds from an initial source using heat and other techniques.

Thus, option D is correct.
