1.81 liters of carbon dioxide are produced when 5.00 grams of hydrogen bicarbonate breaks down.

Mass of hydrogen bicarbonate (H₂CO₃) = 5.00 g

Molar mass of hydrogen bicarbonate = 62 g/mol

Molar mass of carbon dioxide = 44.01 g/mol

Density of CO₂ = 1.97 g / L

Temperature = 25 0C

Pressure = 1.24 atm

Volume of CO₂ = ?

Write the balanced chemical equation

    H₂CO₃ →  CO₂ + H₂O

The molar ratio of hydrogen bicarbonate to carbon dioxide is 1 : 1

It means that when one mole of hydrogen bicarbonate decomposes it will produce one mole of carbon dioxide

Now we will find out the number of moles of hydrogen bicarbonate

    number of moles = mass / molar mass

    number of moles of H₂CO₃ = 5.00 g / 62 g/mol

    number of moles of H₂CO₃ = 0.081 mol

Number of moles of H₂CO₃ = number of moles of CO₂

Hence the number of moles of CO₂ = 0.081 mol

Now find out the mass of CO₂

    mass = number of moles × molar mass

    mass of CO₂ = 0.081 mol × 44.01 g/mol

    mass of CO₂ = 3.565 g

Convert mass to volume

    volume = mass / density

    V of CO₂ = 3.565 g / 1.97 g / L

    V of CO₂ = 1.81 L

Explanation:

These protons, neutrons and electrons are the three fundamental particles of atoms

What is atom ?

The atom is the smallest unit of matter that may be divided without releasing electrically charged particles. It is also the lowest unit of matter that has chemical element features. As a result, the atom is the fundamental building block of chemistry.

Examine various electron configurations in electron shells surrounding an atom's nucleus.

The majority of the atom is empty space. The rest of the structure is made up of a positively charged nucleus of protons and neutrons surrounded by a cloud of negatively charged electrons. In comparison to electrons, the lightest charged particles in nature, the nucleus is small and dense.

The mass of an electron is approximately 9.109382911 1028 gramme. A proton or neutron has a mass that is approximately 1,836 times greater. This explains why the mass of an atom is governed mostly by the mass of its protons and neutrons in its nucleus.

Mass of protons, m

p =1.67×10 −27 kg

Mass of electrons, m

e =9.11×10 −31 kg

Electrons are shared in covalent bonds.

What is a covalent bond?
The exchange of one or more pairs of electrons between two atoms forms a covalent connection. The two atomic nuclei are drawing these electrons in unison. When there is insufficient space between two atoms' electronegativities for an electron transfer to take place and create ions, a covalent bond is formed. Bonding electrons are shared electrons that are present in the region between the two nuclei. The bound pair serves as the "glue" that binds the atoms in molecular structures.

The only covalently bound substance that is the simplest is a hydrogen molecule. Two hydrogen atoms with one electron in each's 1s orbital make up the compound. The covalent link between the two hydrogen atoms allows them to share their two electrons and give each of them a helium-like electron configuration.

The amount of oxygen produced by the reaction of 6.54g of ammonium perchlorate is 2.228g.

The chemical reaction for this will be:

4NH4ClO4 → 5O2 + 6H2O + 2N2 + 4HCl

We know:

'6.54' grams is mass of ammonium perchlorate  and '117.49' g/mol is molar mass of ammonium perchlorate

Now, we  can calculate moles by:

Moles NH4ClO4 =  mass NH4ClO4 / molar mass NH4ClO4

Moles NH4ClO4 = 6.54 grams / 117.49 g/mol

this give 0.0557 moles of NH4ClO4

After this we will calculate the moles of O2 produced similarly:

For 4 moles of ammonium perchlorate consumed, 5 moles of O2 is produced, in addition to 6 moles of  H2O, 2 moles of  N2 and 4 moles of HCl.

For 0.0696 moles NH4ClO4; we get 5/4 * 0.0557 = 0.0696 moles of O2

And Finally we can calculate the mass of oxygen produced:

Mass of oxygen  = moles of O2 * molar mass of O2

Mass of oxygen = 0.0696 moles * 32 g/mol

Mass of oxygen  = 2.228 grams

Explanation:

through the process of electrolysis.

electricity (loose electrons under "pressure") is sent through water allowing the oxygen atoms to bind enough electrons to become independent O2 molecules and detach from water molecules, hence "freeing" themselves as oxygen gas. which in turn also creates free H2 molecules and therefore hydrogen gas.

the free oxygen collects at the positive electrode, the free hydrogen at the negative electrode.

an additional option is to collect the free oxygen that is simply mixed into the water and allows fish to "breathe" (the gills do NOT break oxygen out of the H2O molecules but use the mixed-in free O2 oxygen between the H2O molecules).

that is the reason why a fish tank needs the constant air stream bubbling through the water (or we would have to constantly stir the water in the tank rigorously), and why truly still water bodies "die" (any originally mixed-in oxygen leaves over time, literally suffocating any oxygen-needing lifeforms in those bodies of water).

to capture this, cool the water down to about 4° C (about 39° F), at which point water has its greatest density (below that water expands again preparing for the larger volume needed by the crystalline grid of water ice). that pushes/squeezes a lot of the mixed-in elements incl. free oxygen out of the water.

but that is very little compared to an electrolysis result.

What is condensation ?

Condensation, the separation of a liquid or solid from a vapor, generally occurs on surfaces that are cooler than the adjacent gas. A substance condenses when the pressure exerted by that vapor exceeds the vapor pressure of the substance's liquid or solid phase at the temperature of the surface on which condensation is occurring. As the steam condenses, heat is released. If this heat is not removed, the surface temperature will rise until it matches the surrounding steam.

If the air does not contain small particles, so-called aerosols, condensation will only occur if the air is extremely supersaturated with water vapor.

There will be the formation of a Common salt (NaCl) and Mg(OH)2 which is a base after the reaction between the two chemicals

As we move across period 3 the number of delocalized electrons per metal atom increases and the radius of the elements decreases. This means the melting point increases.

What is melting point and boiling point ?

The temperature at which molecules in a solid can pass one another and transform into liquids is known as the melting point. On the other hand, liquids and gases are involved in the boiling point. Some molecules at the liquid's surface are escaping as the molecules move around.

The three metals' melting and boiling points rise as a result of the strengthening of their metallic connections. Each atom can contribute an increasing quantity of electrons to the delocalized "sea of electrons." As you get from sodium to magnesium to aluminum, the atoms also get smaller and have more protons.

The reaction has a low activation energy and mostly of the reactants are converted into products hence the reaction tends to occur in the forward direction

2) The rate of the reverse reaction is too small compared to  the rate of the forward reaction.

The term reaction has to do with the interaction that occurs between the reactants and the products. Thus as the reactants interacts, a new substance is formed and then we have new substances and they are called  the products. Looking at the reaction as it is written in question (1), we can see that the there is a complete and total interaction that occurs as all the reactants are converted into products. Given the fact that all the reactants are converted into products, the reactions can only proceed forward.

In this reaction, we can see from the equation that the reaction is reversible. This means that the reaction is able to occur in both directions; forward and backwards.

Metal solids tend to be good conductors because of the property of electron mobility.

Metal cations are the building blocks of metallic solids, and a delocalized "sea" of valence electrons holds them all together. Metallic solids are good conductors of heat and electricity because of the mobility of their electrons. Metal atoms bound together by metallic bonds form metallic solids, which are solids. These linkages act as expansive molecular orbitals that cover the entire solid.

The electrons in metallic solids are hence delocalized. They are not only linked together by two atoms in a sigma bond. Metals are effective heat and electricity conductors because they contain at least one free electron per atom, which means that it is not bound to any one atom and is therefore free to travel about the metal.
