2 Types of Charge

 

Vinyl carries negative charge when it is rubbed with wool. Acetate being rubbed against the cotton material causes a positive charge. When two positive are charged they repel and try to move away from each other. When two negatively charged items are charged it causes the two negatively items to repel and try toto get away from each other. When a positive item and a negative item are charged together they attract and try to come together. When a neutral attracts with any charged object it becomes attract

I decided to research compounds with arsenic(As)in it and one cool kind of cool called Calcuim(C) and Arsenate(AsO4). Arsenate is a polyatomic compound which is arsenic(As) and oxygen(O). So the giving formula is Calcium(C) and arsenate(AsO4). Combined it’s Ca3(AsO4)2 because there is 3 calcium atoms and 2 arsenate atoms. The properties of the compound Calcium Arsenate (Ca3(AsO4)2) is the melting point is 2651 *F. The Vapor pressure is 0 mm. The specific gravity is about 3.62. Calcium Arsenate or Ca3(AsO4)2 doesn’t boil it decomposes. It also is a colourless compound it looks like a white powder. The molar mass is 398.072 g/mol. It is mainly used for the protection of cotton crops.

Some of my questions

1.) I read that Ca3(AsO4)2 is very toxic. What happens when Calcium Arsenate touches human flesh?

2.) Also I know that calcium(Ca) is a metal and arsenic(As) is a non-metal so what is the Ca3(AsO4)2 Calcium Arsenate?

Matter Matters

Matters

Define: They’re tons of different parts of matter. It is everything on this earth today so it is important that we know what is so important to us.

Dream: They’re tons of different ways of representing Matter but I made a lot of power points so I decided to make a power point to represent matter

Debrief: I found making this project was very fun and enjoyable. I read 1.2 in the textbook and when I was confused about the subject and I got an answer that I understood. The little five question quiz was a fun way I think to close it out.

Deliver: I made a power point covering all basic concepts of Matter on 1.2. I also made a little five question quiz on the main points(I think) about this section.
