Describe the changes that earths atmosphere has gone to overtime

Chemistry
1 answer:
irakobra [83]3 years ago
8 0

Answer:

Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Tju [1.3M]

Answer:

The pressure would increase because the volume of space the gas takes up decreases once the bottle is squeezed. There is less room for the gas particles to move around meaning more collisions between the particles occur.

What is an aqueous solution compound
Vladimir [108]

Answer:

C. Soluble

Explanation:

An aqueous solution is one in which the solvent is liquid water. That is, solute (dissolved) ions and molecules are surrounded by water molecules and incorporated into the network of bonds within the water. The dissolved species then spread throughout the water

Match the vocabulary word with its definition. Match the items in the left column to the items in the right column. 1. The actua
tekilochka [14]

Answer:

1. The actual amount of product that is produced from a given amount of reactant or reactants.  → actual yield  

2. A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products.    → Conservation of Mass

3. The reactant that is not used up in a reaction that goes to completion

→ excess reactant  

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant  

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

6. The maximum calculated amount of product produced from a given reactant in a reaction that goes to completion. → theoretical yield

7. The study of the quantitative relationships between reactants and products in a chemical reaction. → stoichiometry  

Explanation:

1. The actual amount of product that is produced from a given amount of reactant or reactants.  → actual yield  

  • The actual yield is the actual amount of product that is produced in a chemical reaction and it can be determined experimentally.

2. A law which states that in ordinary chemical reactions, the sum of the masses of the reactants always equals the sum of the masses of the products.    → Conservation of Mass

  • The law of conservation of mass states that mass in an isolated closed system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

3. The reactant that is not used up in a reaction that goes to completion

→ excess reactant  

  • In any chemical reaction between two or more reactants, the excess reactant is the substance that is leftover when the chemical reaction is ended. The amount of product formed is not limited by this reagent.

4. The reactant that limits how much product is produced in a reaction that goes to completion. It is used up in the reaction. → limiting reactant  

  • In any chemical reaction between two or more reactants, the limiting reactant is the substance that is consumed completely when the chemical reaction is ended. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.

5. The ratio of the actual yield to theoretical yield multiplied times 100.

→ percent yield

  • percent yield  = (actual yield / theoretical yield) *100

6. The maximum calculated amount of product produced from a given

reactant in a reaction that goes to completion.

→ theoretical yield

  • theoretical yield  is defined as the amount of the obtained desired product.

7. The study of the quantitative relationships between reactants and products in a chemical reaction.

→ Stoichiometry

  • Stoichiometry is a branch of chemistry that deals with relationships between reactants and/or products in a reaction to determine desired quantitative data.

Observation and experimentation have led many scientists to accept a theory about the origin of the universe, called The Big Ban
34kurt
Red shift is one piece of observational evidence which supports the big bang theory. The fact that galaxies are moving away from us means that the universe was once much smaller, supporting the big bang theory which states that all the matter in the universe once occupied a single point with infinite density.
