Match the following terms with their definitions: homogeneous mixture heterogeneous mixture solution compound 1. matter that is physically combined; has two forms of itself (homogeneous and heterogeneous) 2. a substance that that has uniform composition of two or more substances that cannot be seen 3. a substance that that has non-uniform composition of two or more substances that can be seen 4. substance composed of two or more elements bonded in a certain ratio by mass 5. an example of a homogeneous mixture in a liquid form

Explanation:

A mixture is defined as a substance in which two or more components are mixed together. Components in a mixture do not chemically combine together.

For example, sugar in water.

When solute particles completely and evenly mixed in a solvent then it is known as a homogeneous mixture. A homogeneous mixture is also known as a solution. For example, salt in water.

When solute particles are not evenly mixed in a solvent then it is known as a heterogeneous solution. For example, sand in water.

A compound is a substance in which two or more atoms are chemically combined together in a fixed ratio by mass. For example, is a compound.

Thus, we can conclude that given terms with their definitions are matched as follows.

1. Matter that is physically combined; has two forms of itself (homogeneous and heterogeneous) - Mixture.

2. A substance that that has uniform composition of two or more substances that cannot be seen - homogeneous mixture.

3. A substance that that has non-uniform composition of two or more substances that can be seen - heterogeneous mixture.

4. Substance composed of two or more elements bonded in a certain ratio by mass - Compound.

5. An example of a homogeneous mixture in a liquid form - solution.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

it means there are 3 atoms of oxygen
