Explanation:

1000m³ of Carbon dioxide is required.

Propane is a type of hydrocarbon that is made up of a single carbon-carbon bond.

Propane burns in oxygen completely in a combustion reaction to produce carbondioxide and water.

The balance equation of combustion of propane gas is:

C3H8(g)+5O2(g)→3CO2(g)+4H2O(g).

But noncombustibility of propane is the incomplete combustion of propane which occurs in absence or insufficient oxygen supply.

The balanced equation for noncombustibility of propane is:

2C3H8 + 9O2 → 4CO2 + 2CO + 8H2O

2 moles of propane = 4 moles of CO2

CO21 mole of propane = 2 moles of CO2 (4moles/2moles)

Therefore 500cm³ of propane = 2 × 500

= 1000cm³

Therefore, 1000m³ of Carbon dioxide is required to ensure the noncombustibility of a 500-cubic-meter compartment filled with propane vapor

An ionic or electrovalant bond is a type of chemical bond, which is formed  from two ions (charged atoms by loosing or gaining electrons) having opposite charges.

Ionic bonds are formed from the transfer of electrons from one atom to another. As the electrons are transferred there occurs a positively charged ions (cations) and a negatively charged ions (anions). These ions are held together in a crystal lattice structure by the strong electrostatic attraction between the positively charged cations and negatively charged anions.

The electrons are transferred as the atoms have tendencies to achieve a stable electronic configuration. They do this to attain a stable atomic structure. By transferring the electrons they attain their octet or duplet.

Sodium chloride(NaCl) is formed when the atom of sodium combines chemically with chlorine atom to generate an ionic compound.

Since sodium has an atomic number of 11, its electronic configuration is 2, 8, 1. There is only one electron in the outermost shell of a sodium atom. Therefore, the sodium atom gives one electron to produce the sodium ion Na⁺.

Chlorine has an atomic number of 17. Hence, its electronic configuration is 2, 8, and 7. The chlorine atom contains seven electrons in its outermost shell and requires one more electron to create the inert gas’s stable, eight-electron configuration. Consequently, a chlorine atom accepts one electron and creates the negatively charged chloride ion (Cl⁻).

When sodium interacts with chlorine, it donates its outermost electron to the chlorine atom, forming a sodium ion (Na⁺) and a chloride ion (Cl⁻) by accepting an electron. The strong electrostatic force of attraction between the newly created ions, holds sodium and chloride ions together to create sodium chloride, Na⁺Cl⁻ or NaCl.

Similarly in the case of Magnesium Oxide (MgO) is formed from the chemical interactions of Magnesium and oxygen atoms, leading to the formation of an ionic compound.

Since magnesium has an atomic number of 12, its electrical configuration is 2, 8 and 2, there is just 2 electrons in the outermost shell of a Magnesium atom. Therefore, the magnesium atom gives two electron to produce the Magnesium ion Mg²+ .

Oxygen has an atomic number of 8. Hence, its electronic configuration is 2 and 6, the oxygen atom contains 6 electrons in its outermost shell and requires 2 more electron to create the inert gas’s stable, eight-electron configuration. Consequently, a oxygen atom accepts 2 electronelectrons and creates the negatively charged oxide ion (O²-).

When magnesium interacts with oxygen, it donates its outermost electrons to the oxygen atom, generating a Magnesium ion Mg²+ .  And an oxygen ion (O²⁻) by acquiring 2 electrons. The attractive electrical force holds magnesium and oxygen   ions together to create sodium chloride,        Mg²⁺ O²⁻ or MgO.

The number of moles of nitrous acid used to prepare the solution is 0.0021 moles.

pH of the HNO2 solution =  1. 96

Concentration of the HNO2 solution = Antilog(-1.96) = 0.011 M

We have to set up the ICE table as follows;

         HNO2(aq)   ⇄ H^+(aq)  +   NO2^-(aq)

I      0.011                    0                 0

C     -x                         +x               +x

E     0.011  - x              x                  x

The dissociation constant of the acid is 5.0 × 10−4

Hence;

5.0 × 10−4 = x^2/ 0.011  - x

5.0 × 10−4(0.011  - x ) = x^2

5.5  × 10^-6 - 5.0 × 10^-4x =  x^2

x^2 + 5.0 × 10^-4x - 5.5  × 10^-6 = 0

x= 0.0021 M

The concentration of the acid (H^+) in the solution is 0.0021 M. The number of moles of the acid is obtained from;

0.0021 M × 1 L = 0.0021 moles

Mr. garcia uses magnets to hold a poster on a steel filing cabinet because a main component of steel is iron.

The chemical element iron has the atomic number 26 and the symbol Fe. It is a metal that is found in group 8 of a periodic table and the first transition series. It makes up a large portion of the planet's outer or inner core and is the most prevalent element on Earth by mass, just ahead of oxygen.

It is the fourth most prevalent element in the crust of the Earth, having been mostly deposited by meteorites inside its metallic state, along with its ores. Iron ores must be processed in kilns or furnaces that may reach 5000 °C (2,730 °F) and higher, which is approximately 500 °C (932 °F) greater than the temperature needed to smelt copper.

The gravitational force, which is what pushes mass-containing objects toward one another. We frequently consider the pull of gravity from the Earth. Your body is kept on the ground by this force. However, all mass-bearing objects are pulled toward one another by gravity.

Population growth and changes in people's wants and activities are the main causes behind this. Changes in the overall levels of output and consumption are caused by these main movers.

The driving forces put strain on the environment through these modifications to production and consumption. In the direction of motion, gravity produces an active driving force.

The oxygen atoms have fewer protons than chlorine atoms:) hope this helps:))

According to the electronic configuration, oxygen atoms have fewer protons and electrons than chlorine atoms.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

I think the answer is increases

Answer:Butane > ethane > methane, because between bigger molecules there are stronger van der Waals forces and also higher molar mass means they need to be given more energy to have enough kinetic energy to move quickly, freely in gas.

There are multiple butene isomers (Butene) and some (2-Butenes - cis and trans) actually have higher boiling point than n-Butane (there is also Isobutane, of course, with quite much lower boiling point than all of them) and some (1-Butene, Isobutylene) have lower, so this isn't really a fair or simple question. But on simplest level, it can again be said that 1-butene has lower boiling point because it has very similar shape but slightly lower molar mass (2H less) than n-butane.

Explanation:

Intermolecular forces such as dipole-dipole forces, London dispersion forces exist between molecules and these depend on strength of electronegativity of molecule. Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.

Intermolecular forces of attraction is force of attraction that make two molecule come closer. Intermolecular forces of attraction is directly proportional to the electronegativity of the molecule.

Size of electronegative molecule is small so, if any other molecule or molecule come into contact with this molecule then this molecule attract the electron of other molecule very efficiently and therefore the force between the molecule increases.

Molecules of methane have weak intermolecular forces of attraction. When energy is applied, the methane molecules easily break apart and turn into gas.

Therefore, methane converts to gas on boiling due to weak intermolecular forces of attraction between the molecules.
