Sep 21, 2022 · A combination reaction is a reaction in which two or more substances combine to form a single new substance. Combination reactions can also be called synthesis reactions. The general form of a combination reaction is: A + B → AB A + B → AB. One combination reaction is two elements combining to form a compound.

Compounds. A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen atoms as carbon atoms. Methane is a pure substance because it ...
Jun 13, 2023 · Combination Reactions. Combination reactions describe a reaction like this: A + B → C (1) (1) A + B → C. in which two or more reactants become one product (are combined). The problem with this term is that it doesn't give you much chemical insight because there are many different types of reactions that follow this pattern.

Flour and sugar may be combined to form a mixture.Sugar and water form a mixture.Marbles and salt may be combined to form a mixture.Smoke is a mixture of solidparticles and gases.Two broad categories of mixtures are heterogeneous and homogeneous mixtures. Heterogeneous mixtures are not uniform throughout the composition (e.g. gravel), while homogeneous mixtures have the same phase and composition, no matter where you sample them (e.g., air). The distinction between heterogeneous and homogeneous mixtures is a matter of magni...
Just because you mix two chemicals together, don't expect you'll always get a mixture! If a chemical reaction occurs, the identity of a reactant changes. This is not a mixture. Combining vinegar and baking soda results in a reaction to produce carbon dioxide and water. So, you don't have a mixture. Combining an acid and a base also does not produce...

- Bubble Solution. You can make a simple bubble solution for blowing bubbles by combining liquid dishwashing soap and water, but chemistry holds the secrets to making better bubble solutions that create larger or longer-lasting bubbles.
- Solubility and Saturation. When you dissolve a soluble substance in a liquid, you make a solution. Mixing a lemonade powder (a solute) with water (a solvent), for example, creates a solution.
- Super Cold Slushies. Making a slushy involves turning flavored water or fruit juice into an icy, drinkable treat. In the Homemade Slushies activity, students make slushies and explore the science behind how using a salt-water solution helps the slushy mixture form ice crystals.
- Rock Candy Solution. Making rock candy involves growing crystals from a saturated solution of sugar and water, one that has more sugar than can dissolve in the water.

The law of constant composition can be used to distinguish between compounds and mixtures of elements: Compounds have a constant composition; mixtures do not. Water is always 88.8% O and 11.2% H by weight regardless of its source. Brass is an example of a mixture of two elements: copper and zinc.
