The compounds and elements on the LEFT side of the arrow are called?

Reactants

100

This is the name of the arrow in the equation

 Yield symbol

100

Balance this equation with the correct coefficients:

Mg + Cl2 -->MgCl2

It is already balanced

100

Al + O2 --> Al2O3 is what type of reaction?

Synthesis

100

 Balance this equation: Na + Cl2 -->NaCl

2Na + Cl2 -->2NaCl

200

The compounds and elements on the RIGHT side of the arrow are called?

Products

200

Find the precipitate in this reaction:

Cu(s) + 2AgNO3(aq) -->Cu(NO3)2(aq) + 2Ag(s)

2Ag(s)  Because precipitate means solid!

200

Balance this reaction with the correct coefficients:

 K + Br2 --> KBr

2K + Br2 --> 2KBr

200

SiO2 + HF --> SiF4 + H2O is an example of what type of reaction?

Double replacement

200

What is the correct ratio of coefficients to balance this chemical equation?

Ca + O2 --> CaO

2:1:2

Because:

2Ca + O2 -->2CaO

300

The phase of matter symbol for when something is dissolved in water

 (aq)

300

In this equation 2Mg + O2 --> 2MgO 

2Mg + O2 are the products or reactants?

Reactants

300

 Aqueous Sodium Chloride and aqueous Silver Nitrate react to form solid Silver Chloride and aqueous Sodium Nitrate.      

Write a balanced chemical equation for this:

NaCl(aq) + AgNO3(aq) ---> AgCl(s)  + NaNO3(aq) 

300

2Al2O3--> 4Al + 3O2 is what type of reaction?

Decomposition

300

How many TOTAL atoms are there?

3Mg(NO3)2 


27 total atoms

Mg=3

N=6

O=18

400

The BIG number in front of a compound used to balance an equation is called a...

Coefficient.

400

Does a balanced chemical equation have the exact same number of atoms of each element in reactants and the products?

Yes due to the law of conservation of mass both reactants and products must be equal.

400

Write the Net Ionic Equation for this Ionic Equation:

Na+(aq) + Cl-(aq) + Ag+(aq)+NO3-(aq) --->     

            Na+(aq)+NO3(aq)- + AgCl(s)

Ag+(aq) + Cl-(aq)  --->AgCl(s)

400

What type of reaction is this?

K + NaCl --> KCl  + Na  

Single replacement because only 1 swap is happening (K and Na are swapping).

400

Identify the covalent compounds:

Co            Cu         NH4Cl

CO2               NH3          NaCl

K              P2O5           MgS

             CO2               NH3          

             P2O5         

500

What are three signs of a chemical reaction?

Color change, temperature change, gas, bubbles, light, fire, etc...

500

What product is represented by X?

FeCl2 + Na3PO4 --> X + Fe3(PO)2

NaCl

500

Write the ionic equation for this balanced reaction:

NaCl(aq) + AgNO3(aq) ---> NaNO3(aq) + AgCl(s)

Na+(aq) + Cl-(aq) + Ag+(aq)+NO3-(aq) --->     

            Na+(aq)+NO3(aq)- + AgCl(s)

500

What type of reaction is this? How do you know?

CH4 + 2O2 --> CO2 + 2H2O

Combustion

Because there is a carbon hydrogen fuel source, Oxygen to keep fire alive, and it makes carbon dioxide gas and water vapor.

500

What would be the chemical formula if Magnesium and Bromine ions react? And what would the name be?

Mg2+ and Br- so chemical formula would be MgBr2

Name would be Magnesium Bromide
