Summary: Ionic bonds are when 2 atoms bond together.  To bond one of the 2 atoms has to have a positive charge and the other has to have an negative charge. A covalent bonds is when 2 atoms share the same electrons for potential energy. Covalent bonds happen between 2 non metals. Chemical Reactions need 2 or more atoms to have a different outcome. To know if a chemical reaction is happening you need to see if there is visible gas, bubbling around the surface, fizzing, the temperature of the substance either gets very hot or goes down to very cold, and lastly color changing. The reactants still have the same mass and atoms they just get re arranged.

SP3: Planning and carrying out investigations: We did a lab to create a chemical reaction. Our reactants were baking soda,vinegar and laundry detergent. And our reactants had to yield our product... Sodium Bicarbonate. Our goal was to dry and put different amount of baking soda and vinegar into our test tube to see how much of baking soda and vinegar it would take to reach the top of the test tube(100 ml) without overflowing. (the amount of laundry detergent has to be the same the whole time - 2 drop of laundry detergent). And we knew it was a chemical change because we saw lots of bubbling and fizzing. The exact result to get to the top without overflowing was 1/2 of a teaspoon of  baking soda, 7 ml of vinegar , and 2 drops of laundry detergent.

XCC: Cause & Effect: When you have 2 or more reactants it causes those 2 reactants to rearrange their atoms to create something new. Like our baking soda, vinegar,and laundry detergent experiment all those reactants came together to rearrange their atoms to create Sodium Bicarbonate. When there are 2 atoms they get connected because they are attracted by each others atoms and bond for a chance of potential energy. If your atom has a negative charge it is called a cation. This happens when electrons get added giving the atom an negative charge. If electrons are lost then the atom has a positive charge which makes it a anion.So if a atom is positive its a anion. If it has a negative charge then its a cation.
