Marshmallow Calorimetry

I learned that you can burn all the energy out of a marshmallows and that you can calculate the heat change by using water. I proved that a energy can be burned out of a substance. It shows how we burn calories when we eat and then exercise to burn calories.

Extension
You can calculate the amount of ice that has melted from the heat that emerges from the burning marshmallow.

Thermal Energy

The Metal Block is colder because of its heat capacity.

The thermal energy is released from the metal to the ice causing it to melt fast.

Extension

The Sun warms the earth through heat waves, UV rays, radiation, and most importantly vision rays.

Heating Curves

I learned there are different changes to the heating curves based on the heat and the pressure which is measured in (atm)

It results to show that every item has a different heating curve.

When touching a piece of metal and a piece of wood that has the same temperature the thermal energy in the metal is released to our hand making it seem colder.

Extension
~The cooling curve would be the total opposite of the heating curve.

Intermolecule Forces and Physical Properties

I believe that this two subjects have been the hardest for me to understand by far I like how we did the chemical zoo by seeing examples and presentations done by other study but however; I was confused on VSEPR know what its purpose was and how its used left me puzzled. Intermolecular forces were a little bit better at understanding but still had confusing I learned that water is one of the stronger intermolecular forces.

Covalent Bonds

I learned that there are two different types of bonding that is important in chemistry. Covalent and Ionic bonds are the two different types we learned bout.

 It important that we learn this because to make nonmetal compounds you have to know your restrictions and how its suppose to be written.

I liked having the Bonding Practice it was helpful.

I found the drawing of the Lewis Structure difficult because I'm not sure when to use a double bond or when you don't have enough electrons to satisfy the elements to fill its outer shell.

Id like to know how to correctly write how the Lewis Structure is suppose to be drawn.
