Answer:

Decantation

Explanation:

Decantation is one of the process of separating mixture containing solid and liquid. In this process, gravity plays a very important role. The solid part of the mixture is allowed to settle down. The liquid is removed and separated in another container. It is a process that helps in the purification of the liquid. The particles that are insoluble settles down and is further subject to be separated from the mixture.

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.

Differentiate the 3 types of evolution in Science
Ivenika [448]

Answer:

Brainliest pls

Explanation:

shows the three main types of evolution: divergent, convergent, and parallel evolution.

Divergent: tending to be different or develop in different directions.

Convergent: coming closer together, especially in characteristics or ideas.

Parallel evolution:  implies that two or more lineages have changed in similar ways
