There is a different way to contribute to the CO₂ budget balance besides reducing or turning off this carbon, which would help reduce the amount of greenhouse gases in the atmosphere. However, that depends on the precise amount of carbon that the oceans, trees, and plants are absorbing.
What are the buffering abilities of carbon sinks?The carbon sinks in the cycle have so far had plenty of extra capacity. In fact, since we began burning fossil fuels for energy after the Industrial revolution, about half of the carbon dioxide emissions released into the atmosphere have naturally cycled away again.
A quarter of this carbon dioxide dissolves in water, so the oceans have absorbed it. As they used sunlight to turn it into glucose and oxygen during photosynthesis, plants use up an additional quarter.
The airborne carbon that was captured now exists as trees or is buried in peat, grassland, and soils. It is submerged in the water, dissolving in the deep ocean, or drifting as sediment on the seafloor. In other words, the planet has improved.

The reagent which is completely consumed in a reaction and thereby limits how much product can be formed is called the limiting reagent. Here the limiting reagent is O₂.
What is percent yield?The quantity of the product which is actually made compared with the maximum calculated yield is defined as the percent yield. The percent yield is the ratio of the actual yield to the theoretical yield.
% Yield = Actual yield / Theoretical yield × 100
The number of moles (n) = Given mass / Molar mass
'n' of C₂H₄ = 170.9 / 28.05 = 6.09 mol
'n' of O₂ = 64.1 / 31.9 = 1.65 mol
So O₂ is the limiting reactant.
Theoretical yield of CO₂ is:
170.9 × 1 mol / 28 g × 2 mol / 1 × 44/1 = 537.1 g CO₂

For the Gray Example, what is the total mass of the reactants?
The total mass of the reactants equals total mass of the products, means there is no change in mass during a chemical reaction.
This is due to the law of conservation of mass, which states that the total mass of a system does not change regardless of variations in its components. For mass cannot be created or destroyed, rearranged, or only moved.
In chemical reaction, atoms has rearranged itself to form a new molecules, but the total mass remains the same. It is because the total mass of reactants and products is sum of masses of each atom involved.
So, in any chemical reaction, the total mass of reactants and products remains the same because mass is conserved.

What type of solution would you have if you have a sealed container with 100g of water and 0.15g of dissolved CO2 at 40°C?
If you have 100. 0g of O2, how many grams of Al2O3 will be produced?
If we have 100 g of O₂, the mass in grams of Al₂O₃ will be produced is 477.8 g.
The chemical equation is as follows :
4Al (s) + 3O₂ (g) ==> 2Al₂O₃ (s)
The mass of the O₂ = 100 g
The molar mass of the O₂ = 32 g/mol
The moles of the O₂ = 100 g / 32 g/mol
The moles of the O₂ = 3.125 mol
The 3 moles of the O₂ produces the 2 moles of the Al₂O₃
The moles of the Al₂O₃ = (2/3 ) 3.125
The moles of the Al₂O₃ = 4.687 mol
The mass of the Al₂O₃ = moles × molar mass
The mass of the Al₂O₃ = 4.687 × 101.96

What is mole?Mole is a unit of measurement used to measure the amount of a substance. It is defined as the number of atoms, molecules, ions, or other particles present in a given sample of a substance. The mole is an important concept in chemistry because it allows for direct comparison of the relative amounts of substances in a reaction. It is also used in physics to calculate the number of particles in a given volume. The mole is a base unit in the International System of Units (SI), and its symbol is "mol".
The number of moles of NH3 produced from 14.0 g of N2 can be determined using the following equation:
moles NH3 = (14.0 g N2) / (28.0 g/mol N2) x (1 mol NH3 / 3 mol H2)
moles NH3 = 0.5 mol NH3

The dry hydrogen gas would occupy 0.152 L at 1 atm and 298 K when solving with the combined gas equation.
What is combined gas equation?It is a mathematical expression that states the relationship between the pressure, volume, and temperature.
The gas equation can be stated as:
(P₁V₁)/T₁ = (P₂V₂)/T₂
To solve this problem, we need to use the combined gas law:
We are given the initial pressure (707.3 Torr), but we need to calculate the initial volume and temperature of the hydrogen gas.
P_total = P_H₂ + P_H₂O
where P_H₂ is the pressure of the hydrogen gas and P_H₂O is the vapor pressure of water at 10 °C (9.21 Torr).
P_total = 707.3 Torr
P_H₂O = 9.21 Torr
So, P_H₂ = P_total - P_H₂O = 698.09 Torr
Converting the volume of hydrogen gas collected to the volume at standard temperature and pressure (STP) using the following equation:
V₂ = V₁(P₁/P₂)(T₂/T₁)
Solving for V₁ by rearranging the equation:
V₁ = V₂(P₂/P₁)(T₁/T₂)
Converting the volume of hydrogen gas collected to liters:
V₂ = 125 mL = 0.125 L
Next, we can putting in the values we know:
P₁ = 698.09 Torr
P₂ = 1 atm = 760 Torr
T₂ = 298 K
We can solve for T₁ by using the ideal gas law:
PV = nRT
T = PV/nR
Calculating the number of moles of hydrogen:
n = m/M
n = 0.4 g / 65.38 g/mol = 0.006118 mol
Now we can put in the values we know into the ideal gas law:
T₁ = (P₁V₁)/(nR)
= (698.09 Torr)(0.125 L)/(0.006118 mol)(0.08206 L·atm/mol·K)
= 343.2 K
Finally, we can solve for V₁:
V₁ = V₂(P₂/P₁)(T₁/T₂)
= (0.125 L)(760 Torr/698.09 Torr)(343.2 K/298 K) = 0.152 L
Therefore, the dry hydrogen gas would occupy 0.152 L at 1 atm and 298 K.

What determines the strength of an ionic charge?
The strength of the ionic bond is directly dependent upon the quantity of the charges and inversely dependent on the distance between the charged particles. A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge.
The amount of electrons an atom gains or loses when it forms an ion determines the strength of the ionic charge. An atom becomes positively charged when an electron is lost, and negatively charged when an electron is gained.
The ionic charge increases with the amount of electrons lost or acquired. An ion that has lost two electrons, for instance, will have a higher positive charge than one that has lost only one. Similar to this, an ion with three electrons obtained will have a higher negative charge than one with only one.

Point out which of your chosen scientist’s contributions are present in the modern atomic model and which were eventually disproven and thus are not part of the modern model
The scientist I have chosen is J.J. Thomson, who made significant contributions to the study of atomic structure in the late 19th and early 20th centuries.
Thomson's most well-known contribution is his discovery of the electron, which he identified as a negatively charged particle present in all atoms. This discovery formed the basis of Thomson's "plum pudding" model of the atom, which proposed that atoms consisted of a positively charged "pudding" with negatively charged electrons scattered throughout.
While this model was eventually disproven, Thomson's discovery of the electron and his work on the measurement of atomic and molecular masses laid the foundation for the modern atomic model. Specifically, Thomson's work on mass spectrometry led to the development of more advanced techniques for determining the masses and properties of atoms and molecules, which are still used in modern research today.
