Assume that the test tube shown started out having 10.00 g of mercury(II) oxide. After heating the test tube briefly, you find 1.35 g mercury(II) oxide left and 8.00 g of liquid mercury. How much oxygen gas was produced by the chemical reaction? Show your work.
This problem is providing information about the initial mass of mercury (II) oxide (10.00 g) which is able to produce liquid mercury (8.00 g) and gaseous oxygen and asks for the resulting mass of the latter, which turns out to be 0.65 g after doing the corresponding calculations.
Initially, it is given a mass of 10.00 g of the oxide and 1.35 g are left which means that the following mass is consumed:
[tex]m_{HgO}^{consumed}=10.00g-1.35 g=8.65 g[/tex]
Now, since 8.00 grams of liquid mercury are collected, it is possible to calculate the grams of oxygen that were produced, by considering the law of conservation of mass, which states that the mass of the products equal that of the reactants as it is nor destroyed nor created. In such a way, the mass of oxygen turns out to be:
[tex]m_{O_2}=8.65g-8.00g=0.65g[/tex]

How many cubic meters of carbon dioxide is required to ensure the noncombustibility of a 500-cubic-meter compartment filled with propane vapor
Answer:
200 m^3
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

Explain, in terms of particles, what happens when methane boils and why
the boiling point of methane is lower than that of butane.
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.
What is intermolecular forces of attraction?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.

Define ionic bond and explain the formation of nacl and mgo
a.
Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.
The atom that loses the valence electron is called the electron donor while the atom that accepts the electron is called the electron acceptor.
Ionic bond usually occurs between metals and non metals.
Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.
b.
The force of attraction between Na⁺ and Cl⁻ forms the ionic bond.
In the formation of NaCl, Na has one valence electron in its outermost shell and Cl needs one electron to complete the stable octet configuration. Na donates its valence electron to Cl to form the ionic bond. So, the Na atom becomes positively charged with a charge of +1 while the Cl atom becomes negatively charged with a charge of -1.Since the atoms are now charged, the force of attraction between them forms the ionic bond.
c.
The force of attraction between Mg²⁺ and O²⁻ forms the ionic bond.
In the formation of MgO, Mg has two valence electrons in its outermost shell and O needs two electrons to complete the stable octet configuration. Mg donates its two valence electron to O to form the ionic bond. So, the Mg atom becomes positively charged with a charge of +2 while the O atom becomes negatively charged with a charge of -2.Since the atoms are now charged, the force of attraction between them forms the ionic bond.

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.
