Well everything around you is made of matter in different ways. What's a Physical change and a Chemical change?
A Chemical change is one or more substances which can result in the formation of at least one new substance. For example, Burning paper is a chemical change because its formation is creating new chemicals.
A Physical change is when you change an item appearance or texture. For example boiling water is a physical change because you are changing the appearance.
Hello, my name is Billy. Have you ever wondered what makes up the things around you?
Hey Guys, This is my sister Lily. Hey Lily, what do you want for breakfast?
This is called a Chemical Change. While making eggs and the beacon, the chemical bonds are being broken which causes the eggs to make new bonds and from into a new substance,
2 eggs and 3 pieces of beacon.
Hey Lily, can you make me some Black Tea ?
This is called a Physical Change. Boling water is an example of a physical change because the water vapor it has the same molecular atoms as H20.
Sure Billy, give me 5 minutes and it will be finish.
What's a heterogenous mixture and a homogenous mixture ? A Heterogenous mixture is a mixture that doesn't have the same composition throughout the mixture. For example, Vegetable Soup form heterogeneous mixture. This an example of a heterogenous mixture because varying amounts of the different vegetables and other components of the soup.
On the next slide, I will be explaining what is an Homogenous mixture and an example of that.
What's a Compound and an Element? A Compound is made up of 2 or more substances from the periodic table which forms a new substance. For example Water - Formula: H2O = Hydrogen2 + Oxygen. That's an example of a Compound because the atoms are bonded which causes a chemicals reaction and forms a new substance.
A Homogenous mixture is a mixture that is unevenly distributed. For example Vinegar is an example of a homogenous mixture because of how the mixture is unevenly distributed.
Conclusion, I hope you guys enjoy this and feel free to ask me questions and or feedback. Thank You.
What's an element ? An Element can consist of one atom that cannot be broken down and evenly distributed. For example, Oxygen. Oxygen is consist of an element because Oxygen consist of one kind of atom that cannot be evenly ditrbuted.
