Balancing Equations? 4/15/17

Summary:
Balancing equations can be confusing at times, but there are a few simple steps to follow that can insure that you balance an equation correctly. First of all, you need to find an equation to balance. You definitely need an unbalanced equation otherwise you have nothing to balance. Next, you need to draw boxes around each and every compound. This is so that you do not touch or change the compounds. After that, make an atom inventory. It may sound confusing, but all that means is count the atoms on both sides of the chemical equation. Look at the subscripts next to each atom to find the number of atoms in the equation, if there is no number after the element, then there is only 1. Then, write coefficients for each compound until both sides are equal. The biggest rule is you can never ever ever ever ever ever touch the subscripts, you can only add coefficients. Lastly, you have to continue counting the atoms and adding coefficients until both the reactant and product side are equal.
S&EP-Conducting Investigations:
We conducted an investigation to figure out what caused a precipitate and what it is like. First of all, a precipitate is non dissolving solid that forms when two solutions or liquids combine and react chemically. From this investigation we saw that you know a precipitate was formed when you see a solid after two liquids were combined. The investigation confirmed what I already knew which was that a change in color and fizzing indicates a chemical reaction occurred. In addition to that, I noticed that taking accurate notes on your observations makes a big difference on your understanding. This is especially true when comparing two different things. Since I took good notes during this investigation on the sodium carbonate/ magnesium sulfate combination, as well as the baking soda/ calcium chloride combination I could really understand what a precipitate is.
XCC- Cause & Effect:
We know a chemical reaction is a cause and effect relationship. Something causes a chemical reaction, such as leaving to compounds together and you get a new rearrangement as a result. Most people don't think about it, but there are different types of chemical reactions based on both the reactants and products. For example, one chemical reaction is synthesis. A synthesis reaction is when two elements combine to make a compound. This would look like A + B ----> AB. Another type of chemical reaction would be a decomposition reaction. This is when a compound breaks apart into two elements. Single displacement is another type of chemical reaction. This would look like AB ----> A + B. In this chemical reaction is when a more active element takes the place of another element in a compound and sets the less active one free. This would look like AB + X ----> AX + B. Lastly, there is double displacement. A double displacement is when anions and cations of two different molecules switch forming new compounds. This is sometimes called ionic. An example of this would be, AB + XY ----> BY + AX. Chemical Reactions are an example of a cause and effect relationship that has more than one form.
