Answer:

Molal concentration of glucose = 2.64 m

Explanation:

The excersise can be solved by the formula for colligative property, elevation of boiling point.

ΔT = Kb . m . i

As glucose (C₆H₁₂O₆) is an organic compound, i = 1. (No ions generated)

ΔT = Boiling T° for solution - Boiling T° of pure solvent

Kb = Ebulloscopic constant.

We need data from acetic acid.

Boiling T° of pure solvent: 118.1°C

Kb = 3.22 °C/m

We replace data:

126.6°C - 118.1°C = 3.22°C/m . m . 1

(126.6°C - 118.1°C) / 3.22 m/°C = m

Molality = 2.64 mol/kg

Using diverse nutrient sources can help maintain soil health. Manure and compost add organic matter as well as an array of nutrients, but using just compost or manure to meet the nitrogen needs of the crop every year can result in excessive phosphorus levels in the soil.

Answer:

27 g

Explanation:

From the question,

n = Mv...................... Equation 1

Where n = number of mole of Al₂SO₄,  M = Molarity of Al₂SO₄, v = Volume of the solution.

Given: M = 0.12 mol/L, v = 1.5 L.

Substitute these values into equation 1

n = 0.12×1.5

n = 0.18 mol

Also,

n = Mass(m)/Molar mass (m')

n = m/m'.

m = n×m'......................... Equation 2

Given: The molar mass of Al₂SO₄ = (27×2)+32+(16×4) = 150 g/mol

Substitute into equation 2

m = 0.18×150

m = 27 g

Sound is transmitted by vibrating a object and the waves move through particles.

Explanation:

Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.

This number of molecules is

6.022

and is known as Avogadro's number,

Answer:

C

Explanation:

The oxidation number of Sulphur in SO4^2- is;

x + 4(-2) = -2

x - 8 = -2

x = -2 + 8

x = 6

Now,

the oxidation number of sulphur in H2SO3 is

2 (1) + x + 3(-2) = 0

2 + x -6 = 0

-4 + x = 0

x = 4

Hence, the oxidation number of sulphur changed from +6 to +4 which signifies  gain of two electrons as shown in option C.

Answer:

see explanation and punch in the numbers yourself ( will be better for your test)

Explanation:

If you are given atoms you need to divide by Avogadro's number 6.022x10^23

then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams

mm of sulfur is 32 g/mol

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the grams of sulfur in  1.9x10²³ atoms of sulfur is 9.92g.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance.

Given number of atoms= 1.9x10²³atoms

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

Substituting the values

mole=1.9x10²³÷ 6.022×10²³

mole = 0.31 mole of sulfur

Mole = given mass÷ Molar mass

Molar mass of sulfur=32g/mol

mass of sulfur =0.31 mole ×32g/mol

mass of sulfur=9.92g

Therefore, the grams of sulfur in  1.9x10²³ atoms of sulfur is 9.92g.

Answer:

possibly because of the malleability of metals

Explanation:

In metallic bonding, electrons are delocalized and move freely among nuclei. When a force is exerted n the metal, the nuclei shift, but the bonds do not break, giving metals their characteristic malleability.

Answer: [tex]C_7H_{16}+11O_2\rightarrow 7CO_2+8H_2O[/tex]

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation is:

[tex]C_7H_{16}+11O_2\rightarrow 7CO_2+8H_2O[/tex]

Answer:

0.65moles of HCl was produced

Answer:

A molecular compound is composed of two or more non metallic elements that are held together by covalent bonds.

The two major characteristics of molecular compounds are;

1.) They are held by covalent bonds

2.) They generally have poor conductivity

Explanation:

A molecular compound is one where two or more molecules come together to form a compound. Unlike ionic compounds that combine by the transfer of electrons, molecular compounds form by sharing electrons. The pairing of the electrons is what holds the molecules together and is known as covalent bonding.

A molecular compound has various characteristics, some of which are;

- Generally low melting and boiling points

- Soft solid forms

- Low enthalpy of fusion and vaporization.

But the two major characteristics of molecular compounds are;

1.) They are held together by covalent bonds.

The elements in a molecular compound share their electrons by having their atoms bond chemically to each other.

2.) They generally have poor conductivity

Molecular compounds do not conduct electricity and heat properly. Because they are formed by sharing electrons, they usually have no free electrons left to conduct electricity.

Explanation:

1 mole of Ne occupies 22.4 L

x moles of Ne occupies 18.6 L

x = 1 mole *  18.6 L/22.4 L

x = 0.83 moles

1 mole contains 6.02 * 10^23 atoms

0.83 moles occupies  0.83 moles *  6.02 * 10^23 atoms/1 mole

= 4.9966 * 10^23 atoms = 5.0  * 10^23 atoms

Explanation:

What Adi failed to realize is that the oily substance that was obtained from lavender consists of a mixture of substances. It is not only the required  fragrance that is present in the extract.

This experiment will not work because those other components in the mixture may be erroneously identified when they show up in the mass spectrum of the extract and may be mistaken for the fragrance in question.

Hence the experiment will not work because; if some kind of separation method is not used to identify other impurities in the oil, many other substances may be mistaken for the actual fragrance.
