Equations
What is a coefficient?
This is the reaction that occurs when 1 element takes the place of a different element in a compound.
What is single replacement? or What is single displacement?
When an equation obeys the law of conservation of mass, it is said to be this.
What is balanced?
This is the symbol used to show the physical state is a solid.
What is an (s)
This speeds up a chemical reaction without being permanently changed.
What is a catalyst?
The number 8 in S8 is called this.
What is a subscript?
This reaction occurs when two elements switch places in their compounds.
What is a double displacement reaction?
Or: What is a double replacement reaction?
If I have a balanced equation with 10 K on the left side, this is how many potassium I must have on the right side.
What is 10?
The letter (g) lets me know that the chemical is in this physical state.
This slows down or even stops a chemical reaction.
What is an inhibitor?
These chemicals can be found on the right side of an equation.
What are products?
In this reaction two or more chemicals combine.
What is a synthesis reaction?
The coefficient that goes in the blank to make this a balanced equation.
2CaO + Na --> Na2O + ___Ca
What is 2?
I use this letter to let people know that the chemical is a liquid.
What is (l)
A more reactive element will take the place of this type of element?
What is a less reactive element?
These chemicals can be found on the left side of the equation.
What are reactants?
What is decomposition?
I burn 10 grams of hydrogen, using 160 grams of oxygen. I should get this much water.
What is 170 grams?
The symbol (aq) denotes what physical state?
What is an aqueous solution? Or What is dissolved in water?
If it takes more energy to break the bonds than I get from making new bonds I would say the reaction is this.
What is endothermic
The arrow in a chemical equation doesn't mean "equals", instead it means this term that is also used in traffic.
What is yields.
We call a reaction that takes heat in order to take place, this type of reaction.
What is endothermic?
2 moles of iron reacted with 3 moles of oxygen giving this many moles of Fe2O3
What is 1 mole
If I combine a (aq) with a (l) in a double replacement reaction, I might end up with this (s) falling out of the solution.
What is a precipitate?
Polar compounds are dissolved in this type of liquid.
What is polar, or what is water?
