The rates of chemical reactions
An enzyme is an example of this.
What is a catalyst?
The number that goes in front of the reactants and products is called that.
What are coefficients?
This is a solid that can be formed in a reaction.
What is a precipitate?
This is a display of the elements in increasing atomic number.
What is the periodic table?
This is what Noble Gases are.
What is stable?
You can add one of these to increase the rate of a chemical reaction.
What is a catalyst?
In an atom of 5(O[small 2]H), the small 2 is that.
What is a subscript?
A change in this might be a sign of a chemical reaction and it does not smell good.
What is an odor change?
That was the person who made the periodic table.
Who is Mendeleev?
The two groups underneath the periodic table are called this.
What are the lanthinides and actinides.?
When you increase this, there are more reactants in a given volume which increases the reaction rate.
What is concentration?
You can balance an equation by adding these.
What are coefficients?
A change in this might be both good looking and a sign of a chemical reaction.
What is a color change?
These were first thought of as fire, wind, earth, and water.
What are the elements?
What are nonmetals?
When you increase this, the reaction particles are more exposed to one another.
What is surface area?
These are the substances that precipitate in a reaction.
What are the reactants?
The appearance of these might mark the sign of a chemical reaction.
What are gas bubbles?
Group 1 of the periodic table is called this.
What are the Alkalis.
There are now 118 of these now.
What are the elements?
Decreasing this will slow down the rate of the particles and thus slow the reaction rate.
What is temperature?
These are the substances that are produced and go on the right side of the line.
What are the products?
A change in odor, a change in color, a precipitate formation, and the appearance in gas bubbles may mark this.
What is a chemical reaction?
Group 18 of the periodic table is called this.
What are the Noble Gases?
These are found to the left of the zigzag line on the periodic table.
What are metals?
