The relationship between KMT and sea level rise is 760 nm as the sea level rises because the gas level is increasing.
KMT is described as the behavior of gases and also it is used to explain the macroscopic properties of a gas such as pressure and temperature.
Sea level rise is an increase in the level of the world oceans due to the effects of global warming and burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapped gasses into the atmosphere.
So, the relationship between kinetic molecular theory (KMT) and sea level rise is the distance between sea level and KMT which is 760nm as the sea level is rising because the gas level is increasing.

How are you going to apply your learning in naming compounds in our daily lives?
Answer:
Compounds in our daily life are salt, water, baking soda, sugar, graphite, etc.
Explanation:
We can use the knowledge of compounds to recognise different compounds such as listed above. We can realise what they're made up of and why they are compounds.
Convert 7.6 cm3 to m3
Conversion of 7.6cm^3 to m^3 is 0.0000076m^3
Divide the volume by the conversion ratio to convert a cubic centimeter measurement to a cubic meter measurement. The cubic centimeters divided by 1,000,000 gives the volume in cubic meters.
The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be stated in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
We need to convert between units in order to ensure accuracy and prevent measurement misinterpretation. For example, we do not measure a pencil's length in kilometers. In this situation, one must convert from kilometers (km) to centimeters (cm).
Conversion:
1m = 100cm
1m = 10^2cm
1cm = 10^-2m
1cm^3 = (10^-2)^3m^3
1cm^3 = 10^-6m^3
7.6cm^3 = 7.6 x 10^-6m^3
7.6cm^3 = 0.0000076m^3

The mass of baking soda, NaHCO₃ present in the sample is 2.232 g
What is the percentage mass of a substance?The percentage mass of a substance is the ratio of the mass of a substance a given mixture or compound to that of the total mass of the compound or mixture expressed as a percentage.
Percentage mass = mass of substance/ mass of mixture or compound * 100%The percentage mass of baking soda, NaHCO₃ = 100 - ( 28 + 36)%

Write an equation for the reaction of ammoniacal silver nitrate with phenylethyne. What is the role of ammonia in the reaction?
Equation for the Reaction is C2H2+2AgNO3+2NH4OH→C2Ag2+2NH4NO2+2H2O
Phenylethyne is a type of acetylene. Phenylethyne reacts with ammoniacal AgNO3 and the reaction is known as Tollens’s Test. In the following Tollens test, we get a white precipitate. A white precipitate known as silver acetylene (C2Ag2) is produced.We know that the Tollens reagent can be used to determine whether an aldehyde or ketone functional group is present. We are aware that the Tollens reagent is made up of a silver nitrate, ammonia, and sodium hydroxide solution.A triple bond makes up acetylene, and as silver acetylide also has a triple bond in its structure, the reaction with ammoniacal AgNO3 will result in silver acetylide. Role of ammonia is that it forms silver oxide, but with the addition of more ammonia, this solid precipitate will dissolve and yield a transparent solution of the diamminesilver(I) complex ([Ag(NH3)2]+).Learn more about tollen's test here:

The relative atomic mass is 288.60
What is the atomic mass?The relative atomic mass is the sum of the products of the masses of the percentage abundance of each of the isotopes and the mass of that isotope. Recall that an element is composed of isotopes. These isotopes have the same atomic number but different mass numbers.
This implies that the isotopes have different numbers of neutrons. Let us now obtain the relative atomic mass of the element Flerovium.
Percentage abundance of isotope 1 = 2/10 * 100/1 = 20%
Percentage abundance of isotope 2 = 2/10 * 100/1 = 20%
Percentage abundance of isotope 3 = 6/10 * 100/1 = 60%
Then;
(0.2 * 287.2) + (0.2 * 288.2) + (0.6 * 289.2)

concentration of sulfuric acid is 0.124mol/dm³
Given,
volume of sulfuric acid is 25 cm³
1 dm³ = 1000 cm3.
25.0 cm³ 0.250mol/dm3 NaOH solution contains (25/1000)×0.250 = 0.00625 mol NaOH.
2NaOH + H2SO4 → Na2SO4 + 2H2O
2 moles of NaOH neutralizes 1 mole of H2SO4.
Therefore, 0.00625 moles of NaOH neutralizes 0.00625/2 = 0.00312 moles of H2SO4.
So, the molarity of H2SO4 solution = (0.00312/25) × 1000 = 0.124 mol/dm³.

The value of the equilibrium constant, K of the reaction is 0.055 M
What is the value of the equilibrium constant, K of the reaction?The value of the equilibrium constant, K of the reaction is determined as follows:
Equation of reaction: 2 A (aq) ⇄ 2 B (aq) + C (aq)
Initial moles of A present = 0.88 mol
Volume of solution = 3.00 L
At equilibrium,
moles of C present = 0.150 moles
moles of B present = 2 * 0.150 moles
moles of B present = 0.300 moles
moles of A present = 0.880 - (0.300 + 0.150)
moles of A present = 0.430 moles
