Answers

Answer:

Reactivity! :)

Explanation:

I just took the test! "2.13 Physical and Chemical Changes"

Reactivity is the chemical property of the substance. Therefore, option (C) is correct.

What are the chemical properties?

A chemical property can be described as the property that causes a change in the chemical structure of the substance. A chemical property of a substance can be seen in chemical change or reaction in the substance.

A chemical property represents the ability of a substance to combine with other substances or convert into a different product.  The chemical composition is the identity of the substance and on changing it the substance turns into a different substance.

A chemical property gets determined when a change occurs in the chemical identity of the substance. The chemical properties such as toxicity, reactivity, enthalpy of formation, the heat of combustion, oxidation states, radioactivity, etc.

The color, melting point, and boiling point are the physical properties of a substance while reactivity is the chemical property.

The molecular mass of CO2 is 44.01 u. What is the mass of 2.0 mol of CO2?

Answers

Answer:

The mass of 2.0 mol of C02 is 44 grams

Explanation:

The weight of CO2 is 44 grams per mole (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms)

According to the mole concept, the mass of 2.0 mole of carbon dioxide is 88.02 u.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons.Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

Mass can be calculated by the number of moles formula as,

mass=number of moles×molar mass

=2×44.01=88.02 u.

Thus, the mass of 2.0 mole of carbon dioxide is 88.02 u.

Explain why the name 1-propene is incorrect.what is the proper name for this molecule​

Answers

Answer:

Explanation:

Explain why the name 1-propene is incorrect what is the proper name for this molecule

The name 1-propene is incorrect because;

It is not necessary to indicate the position of the double bond. Whichever way you decide to flip it, the double bond will always be at the first carbon.

The proper name for this molecule is;

Propene

Propene otherwise known as propylene is simply propane with a double bond at the first carbon.

When we get to the alkenes where the naming of organic compounds becomes more complex, the numbering system is used to indicate the position of the bonds.

With propene, there are three carbon atoms and the double bond will always appear in between two of the carbon atoms.

So, it is not important to use numbers to show that the carbon is at the first carbon. This becomes necessary from the next compound, butene, where there are more carbons.

much volume (mL) would 29 grams of copper have? While it is helpful for
you to show all work, you MUST provide rationale for your thinking and
explanation for each of your steps.

Answers

The volume of copper : 3.24 ml

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

[tex]\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}[/tex]

ρ = density , g/cm³ or kg/m³

m = mass , g or kg

v = volume , cm³  or m³

A common example is the water density of 1 gr / cm³

The density of copper : 8.96 gr/ml

mass of copper : 29 g

then the volume :

[tex]\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{29~g}{8.96~g/ml}\\\\V=\boxed{\bold{3.24~ml~or~3.24~cm^3}}[/tex]

Answers

Answer : The correct formula of manganese(II) chloride and manganese(II) oxide is [tex]MnCl_2[/tex] and [tex]MnO[/tex] respectively.

Explanation :

As we know that the chemical formula is formed by the criss-cross method.

In criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions.

For formation of manganese(II) chloride, manganese will form having an oxidation state of +2 called as cation and anion is chloride with oxidation state of -1.Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral  .

For formation of manganese(II) oxide, manganese will form having an oxidation state of +2 called as cation and anion is oxide with oxidation state of -2.Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral  .

Hence, the correct formula of manganese(II) chloride and manganese(II) oxide is [tex]MnCl_2[/tex] and [tex]MnO[/tex] respectively.

[tex]MnCl_{2}[/tex] ---> Manganese(II) chloride[tex]MnO_{2}[/tex] ----> Manganese(IV) oxide

The oxidation number of oxygen is -2, and that of chlorine is -1

Which two elements are
most likely to bond with
each other?
A. Oxygen and Boron
B. Nitrogen and 3 atoms of
Hydrogen
C. Chlorine and Calcium
D. Neon and Sodium

Answers

Answer:

c

Explanation:

i hope this helps

The two chemical elements that are most likely to bond with each other are: C. Chlorine and Calcium.

A chemical bond refers to the forces of attraction existing between ions, crystals, atoms or molecules and that are typically responsible for the formation of new chemical compounds.

In Chemistry, there are three (3) main types of chemical bonds and these are:

I. Hydrogen bonds.

II. Covalent bonds.

III. Ionic bonds.

An ionic bond can be defined as a chemical bond which involves a metallic element transferring one or more electrons to a non-metallic element.

In this scenario, the element Chlorine which have seven valence electrons would accept an electron from Calcium (Alkali metal) to form a chemical compound called calcium chloride.

In conclusion, two chemical elements that are most likely to bond with each other by forming an ionic bond are Chlorine and Calcium.

A flask contains the liquids trichloromethane (chloroform) and water. They are separated using a separating funnel, which conclusion can be made from this observation alone?


A. Trichloromethane and water have different relative molecular masses

B. Trichloromethane and water have different boiling points

C. Trichloromethane has a higher density than water

D. Trichloromethane is more volatile than water

E. Trichloromethane and water do not mix

Answers

Answer:

A

Explanation:

Based on the observation that trichloromethane (chloroform) and water can be separated using a separating funnel, the conclusion that can be made from this observation alone is:

E. Trichloromethane and water do not mix.

When two substances are immiscible, such as trichloromethane (chloroform) and water, it means that they do not dissolve or form a homogeneous mixture when combined. Instead, they form separate layers within the mixture.

The immiscibility between trichloromethane and water is primarily due to their different polarities and intermolecular forces. Trichloromethane is a nonpolar compound with relatively weak intermolecular forces, while water is a highly polar compound with strong intermolecular forces.

Water is a polar molecule due to its bent shape and the presence of electronegative oxygen atoms that create partial positive and negative charges. Trichloromethane, on the other hand, is a symmetrical molecule with four chlorine atoms surrounding a central carbon atom, resulting in a nonpolar distribution of charge.

The fact that these two substances can be separated using a separating funnel indicates that they are immiscible, meaning they do not mix or dissolve in each other to form a homogeneous solution. Trichloromethane and water have different polarities and intermolecular forces, causing them to form separate layers in the separating funnel.
