Describe the composition of a molecular compound. What are two major characteristics of molecular compounds?

Answers

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.

If 335 g water at 35.5C loses 5750 J of heat, what is the final temperature of the water?

Answers

Answer:

The final temperature is  39.58 degree Celsius

Explanation:

As we know

Q = m * c * change in temperature

Specific heat of water (c) = 4.2 joules per gram per Celsius degree

Substituting the given values we get  -

5750 = 335 * 4.2 * (X - 35.5)

X = 39.58 degree Celsius

Adi loves the smell of lavender, so she decides to press a few petals of the flower until they release a few drops of oil. She wants to determine the molecular weight of the oily substance to try to identify the fragrance she likes so much. Her lab instructor tells her that her experiment will not work. Why do you think it will not work?

Answers

Answer:

See Explanation

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.

4.What is the right most significant figure in the answer ?

Answers

Answer:

See explanation

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

the coefficient of the scientific notation answer =5.0

the exponent of the scientific notation answer = 23

significant figures are there in the answer = 5

the right most significant figure in the answer = 1

1.9x10^23 atoms of sulfur to grams of sulfur

Answers

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.

What is mole?

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.

Complete question:

A ball with a weight of 0.5 kg is sitting on a shelf that is 3 meters high. What is the gravitational potential energy of the ball ?

Help me! This is 8th grade sci btw

Answer:

the gravitational potential energy of the ball is is 14.7 J.

Explanation:

mass of the ball, m = 0.5 kg

height above the ground on which the ball is sitting, h = 3 m

The gravitational potential energy of the ball is calculated as follows;

P.E = mgh

P.E = 0.5 x 9.8 x 3

P.E = 14.7 J

Therefore, the gravitational potential energy of the ball is is 14.7 J.

Which of the following answers below is the correctly balanced half-reaction for the reduction of the SO4 ^-2 ion in acid solution? The answer is C, but I don’t understand why. Thanks in advance :-)

Answers

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.

Answers

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:

How many grams of glycerine, C3H8O3, are needed to make 100. mL of 2.60 M solution?

Answers

Answer:

the mass of the glycerine needed in the given solution is  23.92 g

Explanation:

Given;

molarity of the solution (C₃H₈O₃), C = 2.60 M

Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M

The molarity of a solution is given as follows;

[tex]Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole[/tex]

The molecular mass of the given solution;

molecular mass = (12 x 3) + (8 x 1) + (16 x 3)

molecular mass = 92 g/mol

The mass of the glycerine needed in the given solution is calculated as follows;

reacting mass = amount of solute (moles)   x   molecular mass (g/mol)

reacting mass = 0.26 x 92

reacting mass = 23.92 g

Therefore, the mass of the glycerine needed in the given solution is  23.92 g
