a) Table salt: it is a compound. A compound is a combination of atoms in fixed proportions.Table salt is NaCl, which means that table salt is a compound of 1 atom of Na and 1 atom of Cl and not other thing. b) Blood: is an homogeneous mixture: it is a mixture of many compounds which can not be easily distinguished or separated, you need microscopes or very special physical methods to distinguish or separate the different compounds of blood. d) Steel: it is a special king of homogeneous mixture (it is called an alloy) which, as in the case of blood, cannot be distinguished or separated easily. d) Planet earth: it is a heterogeneous mixture. You can easily distinguish many of the compounds of the planet Earth: water, oxygen, carbon,...

Combustion

Explanation:

This reaction is called a combustion reaction. It is very peculiar to reactions involving hydrocarbons.

In such reactants, oxygen gas is used as a reactant. It combines with fuel usually the hydrocarbon to produce heat and light energy.

For the combustion of most hydrocarbons, water and carbon dioxides are usually the product.

An element is made up of only one type of atoms and known for its unique properties than other elements.

2. Heterogeneous - composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture

3.Homogenous - even distribution of parts throughout the whole mixture; not easily separated into individual components.

4. Product - the substance created as a result of a chemical reaction

Products are the final substance that created as a result of a chemical reaction.

5. Reactant - one of the starting substances (ingredients) that is involved in a chemical reaction

Reactants are the starting substance that takes part in a chemical reaction.

6. Solute - the substance that is being dissolved.

A Solute is a substance that is being dissolved in the solvent to make a solution.

7. Solvent - the substance that does the dissolving
