Identify processes that change matter to a liquid state.

Answers

Answer 1

Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation.

Answer 2

When the temperature or pressure of a system change, there occurs a change in the state of matter. The process that change the solid state into the liquid state is called the melting.

What is melting?

The process in which the solid is changed into a liquid is defined as the melting. The temperature at which a solid change to a liquid is known as the melting point.

The other process in which a gas changes to a liquid is known as the condensation. This process is found to be the reverse of evaporation, where liquid water becomes a vapor.

Thus the two processes that change matter to a liquid state are melting and condensation.

What will be the mass of 9.95 liters of propane gas (C3H8) at STP?

Answers

Answer:

19.5g

Explanation:

Given parameters:

Volume of propane gas = 9.95L

Unknown:

Mass of propane gas =  ?

Solution:

To solve this problem, find the number of moles first.

    At STP;

        22.4L of gas makes up 1 mole

         9.95L of gas will have a [tex]\frac{9.95}{22.4}[/tex]    = 0.44mole

So;

   Mass of propane gas  = number of moles x molar mass

Molar mass of propane  = 3(12) + 8(1)  = 44g/mol

    Mass  = 0.44 x 44  = 19.5g

A heavily wooded area needs additional solar collectors to meet energy demand. Which statement describes a possible environmental consequence of adding these collectors?

A.
The amount of air pollution will increase.

B.
The amount of water pollution will increase.

C.
More trees will need to be planted to insulate the solar collectors.

D.
Trees will need to be cleared for the solar collectors to work efficiently.

Answers

Answer:

C

I think not positive good luck tho

A heavily forested area is one that has a dense and large number of trees. The areas like mountainous tracks or the protected frosts areas of wildlife.

In order to have solar collectors that meet the demands of energy generation. Some parts of the forests may have to clear off. As for collecting the sunlight, there needs to be clear ground. As trees and forests absorb insolation.

Hence the option D is correct, trees need to to be cleared for working efficiently.

Use the Internet to list five examples of elements with their properties and five examples of compounds with their properties.

Answers

Answer:

here you go

Explanation:

5 elements and properties:

Boron- The chemical properties of boron are more similar to carbon and silicon than elements of its own group, although boron is more electron deficient. Boron has a high affinity for oxygen-forming borates, and reacts with water at temperatures above 100 °C to form boric acid and other boron compounds.

Carbon- As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. The most common isotope of carbon has 6 protons and 6 neutrons, and has an atomic mass of 12.0107 amu. Its ground state electron configuration is 1s22s22p2.

Nitrogen-  Nitrogen gas (chemical symbol N) is generally inert, nonmetallic, colorless, odorless and tasteless. Its atomic number is 7, and it has an atomic weight of 14.0067. Nitrogen has a density of 1.251 grams/liter at 0 C and a specific gravity of 0.96737, making it slightly lighter than air.

Oxygen- is the air you breath

Nickel- Nickel is a hard silver white metal, which forms cubic crystals. It is malleable, ductile, and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C

5 compounds and properties:

Water - Formula: H2O = Hydrogen2 + Oxygen. ...

Hydrogen Peroxide - Formula: H2O2 = Hydrogen2 + Oxygen2 ...

Salt - Formula: NaCl = Sodium + Chlorine. ...

Baking Soda - Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. The rate of this reaction can be changed by changing the size of marble chips.
Describe experiments to investigate what effect using smaller marble chips has on the rate of this reaction.

Answers

Answer:

See explanation

Explanation:

We know that surface area is an important determinant factor in the study of reaction rate. This is the reason why finely divided marble chips react faster than lumps of marble in the reaction between marble chips and dilute HCl.

Now imagine that i have a lump of marble and i have finely divided marble. Then i also have a solution of 0.5 M dilute HCl. If i introduce 1g of the lump  of marble into 250 ml solution of the 0.5 M HCl in one beaker and introduce 1g of finely divided marble into another 250 ml solution of 0.5 M HCl in a separate beaker, we will notice that the finely divided marble chips reacts faster as evidenced by the quicker effervescence of CO2 gas from the later compared to the former.

Hence, smaller marble chips reacts faster with dilute HCl than a lump of marble.

mass of excess left :  4.86 g

Further explanation

Given

5.4 g Al

300 mL of 0.2 mol/L HCl

Required

limitng reactants

volume of the gas(H₂)

mass of salt

mass of excess left

Solution

Limiting reacttant

Reaction

2Al + 6HCl → 2AlCl₃ + 3H₂

mol Al = 5.4 g : 27 g/mol = 0.2

mol HCl = 0.3 L x 0.2 mol/L = 0.06

mol : coefficient of reactants :

Al = 0.2 : 2 = 0.1

HCl = 0.06 : 6 = 0.01

HCl as a limiting reactant(smaller ratio)

Al as an excess reactant

volume of H₂

mol H₂ = 3/6 x mol HCl = 3/6 x 0.06 = 0.03

volume (STP : 1 mol=22.4 L) :

= 0.03 x 22.4 L

= 0.672 L

mass of salt(AlCl₃)

mol AlCl₃ = 2/6 x mol HCl = 2/6 x 0.06 = 0.02

mass AlCl₃ :

= mol x MW

= 0.02 x 133.5

=2.67 g

mass of excess(Al) left

mol (reacted) : 2/6 x mol HCl = 2/6 x 0.06 = 0.02

mol (unreacted) : 0.2 - 0.02 = 0.18

mass = 0.18 x 27 g/mol = 4.86 g

Why do we sometimes use roman numerals in naming ionic compounds?

Answers

Roman numerals are used in naming ionic compounds when the metal cation forms more than one ion. The metals that form more than one ion are the transition metals, although not all of them do this.

We use roman numerals to indicate the oxidation state of metal atoms when naming compounds especially in the case of coordination compounds. It is a standard system of nomenclature.

What is oxidation state?

Oxidation state of a species is the number electrons gained or lost. Oxidation state increases if electrons are lost from the atom and it will be decreased if electrons are gained.

For example, copper is in + 2 oxidation state in CuSO₄, thus it can be indicated as Cu(II). Copper can exists is +3 oxidation too. Thus the representation will be Cu (III).

All the transition metals like copper exhibit various oxidation state. So it is important to indicate in which oxidation state they are in a particular compound. In the compound Fe₂O₃, iron is in + oxidation state whereas in FeSO₄, it can be +2 . Thus it is important to note whether it is Fe (II) or Fe (III).

the electrolyte in automobile lead storage batteries is a 3.75 sulfuric acid solution that has density of 1.230g/mL. calculate the mole fraction.

Answers

The mole fraction of sulfuric acid : 0.073

Further explanation

Given

3.75 M sulfuric acid solution that has density of 1.230 g/mL

Required

The mole fraction

Solution

3.75 M = 3.75 mol/L

For 1 L solution :

mass of solution = 1230 g

mass Sulfuric acid : 3.75 mol x 98 g/mol=367.5 g

mass water = 1230-367.5 = 862.5 g

mol water = 862.5 : 18 g/mol= 47.92

mol total = 3.75 + 47.92 = 51.67

mole fraction of sulfuric acid :

= 3.75 : 51.67

A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.

What is Chemical Bonding?

Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound.

Ionic bonding occurs by transfer of electrons from one atom to another and is usually between a metal and a non metal atom. This type of bond is classically described as occurring when atoms interact with one another to either lose or gain electrons.

Metallic bonds are the chemical bonds that hold atoms together in metals.

Therefore, A crystal of Gold (Au) has metallic bonding whereas a crystal of NaCl has ionic bonding.
