Is Cake Batter Homogeneous Or Heterogeneous?

The cake batter is considered homogeneous if it appears to be a single liquid when you pour it from one container into another. But, it’s really not. Cake batter is made up of tiny little particles called flour that are suspended in the liquid. This makes it heterogeneous.

In fact, most liquids are heterogeneous. When you look at water in a glass, you’re seeing all those tiny little H2O molecules. They’re so small, they’re actually invisible to the naked eye.

When you add sugar to water, it bonds with the H2O molecules to form a solution. That solution contains tiny droplets of sugar that are suspended in the liquid. This is known as a colloid.

All matter is made up of atoms and molecules. But, atoms and molecules can only join together in certain ways and create stable structures. When they do, we call it a molecule. For example, water is made up of two hydrogen atoms and one oxygen atom. The oxygen atom is very active and likes to bond with other atoms. This makes water very unstable and causes it to change shape easily. But, because of the way the hydrogen atoms are bonded, water has a stable structure and will always exist in the form of a H2O molecule.

Matter is incredibly complex. It’s easy to think that something you are looking at or touching is a single substance. But, most things are made up of hundreds of different substances that work together to create an integrated whole.

In chemistry, there are four main types of bonding: ionic, covalent, metallic and non-metallic.

Ionic bonds are formed when an ion (an atom with an unbalanced amount of positive or negative charge) attaches itself to another atom or molecule. This creates a bond between the two components. Think about the positive and negative ends of a battery as ions. They are attracted to each other with an Ionic bond.

Covalent bonds are formed when two atoms share two electrons with each other. Think of them as sharing a pair of scissors. When one of the atoms don’t have any more electrons to give, it will “scissor” the electron from the other atom. Then, both atoms will have one less electron and will be balanced. This leaves a bond between the two atoms. Covalent bonds are very strong and are found in all elements on the Periodic Table.

Metallic bonds are formed when an atom has too many electrons and is missing one or more electrons. An atom that has too many electrons is called an “electron-donor” and one that is missing electrons is called an “electron-acceptor.” Think of an atom like a dimmer switch. When you turn it all the way up, it gives off a cloud of electrons. When you turn it down, it absorbs electrons. Metallic bonds are weak and can be easily broken. For example, gold is often used in dental fillings because it will bond to other substances. But, if it could talk, it would tell you it only forms a metallic bond with other gold atoms. It does not form any covalent or ionic bonds.

Non-metallic bonds are formed when two atoms share an orbital. This creates a bond between the two atoms. Think of it as a pair of “hands” holding the atoms together. If the atoms are closer together, they will have a stronger bond. The closer the atoms are, the higher the energy required to separate them.

There are three main types of non-metallic bonds: Π (Planar), σ (Spherical) and δ (Tail). The strength of the bond will determine what type of molecule is created. For example, Π bonds are the weakest and are found in hydrocarbons. They are very stable and are the basis for all organic molecules.

Σ bonds are stronger than Π bonds and are found in all other organic molecules. They are formed when two atoms share one electron in an orbital. This creates a bond between the two atoms.
