How many mole are in 2.84*10^22 molecules of h2

Answer: higher temperature / more kinetic energy / more space between particles / higher volume.

Explanation:

1) One postulate of the kinetic theory is that the average kinetic energy of gas particles is proportional to the absolute temperature of the gas.

That means that the higher temperature, the higher the kinetic energy of the molecules, which is the start of the sequence of the relationship between temperature and volume.

2) Since average kinetic energy is proportional to the square of the speed, KE = [1/2] mass × (speed)², it follows that at higher the kinetic energy the faster the molecules will move.

3) By moving faster, the particles will collide more frequently so they will move away from each other, occupying more space.

4) More space between the molecules, is more volume.

So, the sequence is complete: higher temperature → higher kinetic energy (higher speed) → more space → more volume.

The answer is: higher temperature/ more kinetic energy/ more space between particles/ higher volume

Answer:

Synthesis - 4

reversible- 2

exchange- 1

decomposition-3

Explanation:

In synthesis reaction two or more components combines to form a single product. example 2H2+O2⇒2H2O

In reversible reaction two reactants combine to form two products . The products then reacts and forms back the reactants. example N2 +3H2 ⇒2NH3

In exchange reaction there is an alternation of ions of reactants to form new products. AB+CD ⇒AC + BD

In decomposition reaction, molecules of a compound break down by the action of heat or light or catalyst. example CaCO3 ⇒CaO +CO2

Final answer:

Synthesis involves creating new molecules from components, while Decomposition involves breaking molecules down into their separate elements. Exchange is when molecules rearrange and form new molecules, and Reversible reactions can go forward or backwards.

Explanation:

In chemistry, various types of chemical reactions have different characteristics. Here's how they match with the provided definitions:

• Synthesis corresponds with 'molecules formed from components'(4) since synthesis is a type of chemical reaction where two or more simple substances combine to form a more complex substance.
• Reversible doesn't correspond directly with any of these definitions, but it designates a reaction that can proceed in either direction - from reactants to products or from products back to reactants.
• Exchange relates to 'molecules rearrange and form new molecules'(1) because an exchange reaction is one in which compounds exchange elements or groups in order to form different compounds.
• Decomposition is 'bonds broken and elements released'(3). In a decomposition reaction, a compound is broken down into simpler substances.

The quantum mechanical model of the atom was developed by Erwin Schrödinger. The correct option is B

What is Erwin Schrödinger theory?

Austrian physicist Erwin Schrödinger created the quantum mechanical model of the atom in 1926. The development of quantum mechanics, a fundamental physics theory that describes how matter and energy behave at the atomic and subatomic scales, was significantly aided by Schrödinger's work.

The behavior of electrons in atoms was mathematically described by Schrödinger's wave equation, which combined wave-like and particle-like characteristics. His work transformed our understanding of the atomic universe and formed the basis for contemporary quantum theory, along with the contributions of other scientists like Werner Heisenberg and Max Planck.
