Week 28: Balancing Equations and Burning Butane!

Maddie,

Happy Saturday! I hope you're enjoying your weekend!

I feel this week we really comprehended different types of chemical equations as well as how to balance them.The three worksheets we got last week were quite helpful in undetstanding chemical equations as a whole.

A Single repalcement is when a ionic compound is broken up by a cation or an anion to form another ionic compound with a different byproduct. A double replacement is where two ionic compounds come togethr and basically flip flop so that the cations are  paired with new anions, and there is no byproduct in this  type of chemicla equation.

Another  part of chemical equations are synthesis and decompsition. Synthesis is where two ( or possibly more)  Ions are put together to for an ionic compound.  An Ionic compoung that returns to it's individual ions is called a decomposition,while thse processes are two sides of the same coin, they are both very different and easy to mix up, i almost putsynthesis when it was actually decomposition on the assesment on friday, Margo noticed the slip up and saved me!

Combustion is my favorite chemical reaction! This is when  the product of the reaction is  Water and Carbon dioxide,  and that's all! I think that it's so cool that there is a seperate category for this reacttion.

Finally Balancing the equations is always about having the same ammount of molecules that you started with  on the left side to end up on the right side,  so i usually draw a diagram with little  dots, some colored  in and osme left blank, to sort out how many of each molecule i need, and to correctly balanace the equation,  during our group assesment, the liuttle tiny dots were how we showed " particle diagrams for each reaction!

   The best part of ChemTeam this week was lighting the  t-shirt strip doused in Butane and becuase of the string, we could "hold the fireball" The fact that  it was burning the butane and NOT our fingers was  the coolest thing  to me! Look at the picture i took, it looks like Mr. Abud can shoot fire from his hands! ( don't make him mad, jk!)
