This reaction is an example of what type of reaction? H2SO3(aq) H2O(l) + SO2(g)a. a synthesis reaction
b. a disynthesis reaction
c. a combustion reaction
d. a decomposition reaction

Answers

Answer 1

Answer: This reaction H2SO3(aq) H2O(l) + SO2(g) is an example of what a decomposition reaction. It is not a replacement reaction because no other compound is involved. It is not a combustion reaction because no oxygen is involved.

Answer 2

Answer:

Answer: Option (d) is the correct answer.

Explanation:

A chemical reaction in which a compound dissociates to give two different compounds or atoms is known as a dissociation reaction.

For example, $H_(2)SO_(3)(aq) \rightarrow H_(2)O(l) + SO_(2)(g)$

Here, sulfurous acid dissociates into water and sulfur dioxide gas. Both water and sulphur dioxide have different properties than sulfurous acid.

Therefore, we can conclude that the given reaction is an example of a decomposition reaction.

What is first and second element of the periodic table?

Answers

The elements on the periodic table are listed in increasing atomic number.

Hydrogen is the first element, and has an A.N. of 1. Also, its very interesting how it doesn't need 8 valence electrons to be stable.

The second element is Helium, which has an A.N (atomic number) of two.

The first element of the periodic table is hydrogen (H), and the second element is helium (He).

Hydrogen, with atomic number 1, is the first element in the periodic table. It is the lightest and the most abundant element in universe. Hydrogen is a colorless, odorless gas and is the building block for all other elements.

Helium, with atomic number 2, is the second element in the periodic table. It is also a gas, but unlike hydrogen, it is inert and does not readily react with other elements. Helium is known for its low density, which makes it lighter than air, and it is commonly used for filling balloons and as a cooling medium in various scientific and industrial applications.

So, the first element of the periodic table is hydrogen (H), and the second element is helium (He).

b. unbonded electrons.
c. bonds.
d. movement of the electrons.

Answers

The answer is C. bonds. Because chemical energy in compounds is stored in bonds between the molecules involved.

Further Explanation

Energy is the ability to do work, where work is the movement of objects by force. We use energy every day, and energy comes in different forms. Chemical energy is energy stored in chemicals, such as sugar and gasoline.

Chemical energy is energy stored in chemical compounds in the form of bonds between one atom with another atom. Chemical energy is an energy produced in a chemical process. The amount of energy produced depends on the type and amount of reagents in a chemical reaction. Devices that can produce energy from chemical reactions such as batteries and batteries.

Chemical Energy Sources

chemical allergens are stored in molecular bonds and when these bonds break, heat is released or absorbed. These molecules are part of chemical compounds or fuels such as coal, oil, biomass, wood, animal waste, natural gas, food, etc. and they are all sources of chemical energy that generates heat usually through combustion. Chemical energy sources can be classified into two types, depending on whether they are naturally or artificially prepared and depending on their natural state (solid, liquid, or gas):

Solid Fuel: wood, coal, lignite, etc.
Liquid fuels: gasoline, diesel, alcohol, kerosene, etc.
Gas Fuel: natural gas (coal gas, water gas, biogas)

All of these fuels contain hydrocarbons - organic compounds containing carbon and hydrogen - various molecular weights. These hydrocarbons may be alkanes (methane, ethane, propane, etc.), alkenes (ethene, propane, etc.), cycloalkanes, aromatic hydrocarbons, and heterocyclic compounds.

Which is more important in determining a compound’s melting points, polarity or molar mass? Why?

Answers

Both polarity and molar mass affect the melting points of a compounds. However, polarity is more prioritized for compounds of similar molar mass. The order of increasing melting point follows: non-polar < polar < ionic.

Ionic compounds have the strongest forces holding them which is why it requires higher temperature to overcome those forces. Next, polar substances have weaker electrostatic forces than ionic compounds, but have stronger forces than non-polar compounds due to the presence of dipole-dipole interaction. The force present in non-polar compounds is Van Der Waals forces.

in determining a compound's melting points, polarity is more important

Every compound is contained by molecules.

Polarity determine how much energy is needed to break these molecules, meanwhile molar mass only determine the weight of the molecules. Even though molar mass do affecting the boiling point, it's not as much as the basic resistance of the separation of inter molecular forces does.

A gas cylinder contains 2.0 mol of gas X and 6.0 mol of gas Y at a total pressure of 2.1 atm. What is the partial pressure of gas Y?

Answers

The answer is 1.6 atm. Let's first calculate the mole fraction of gas Y. The mole fraction (x) is: x = n1/n, where n1 is a number of moles of an individual gas in a mixture and n is total moles of the gas mixture. We know that n1 of gas Y is 6.0 mol (n1 = 6.0 mol) and that there are in total 8. mol of the gas mixture (n = 2.0 + 6.0 = 8.0 mol). Now calculate the mole fraction of gas Y. x = 6.0/8.0 = 0.75. Now, let's use the mole fraction of gas Y (x) and the total pressure (P) to calculate the partial pressure of gas Y (P1): x = P1/P. P1 = x * P. If x = 0.75 and P = 2.1 atm, then the partial pressure of gas Y is: P1 = 0.75 * 2.1 atm = 1.6 atm.

yes, this would be 1.6 atm
