Why do chemists balance chemical equations?
being able to write a balanced equation for a reaction is very important. By balancing an equation we can tell how much material we will need to start with, what the likely products to form, and how much of these products will form
What is the chemical equation of radium and (CO3)-2?
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
What steps are needed to determine the amount of excess reagent in a chemical reaction?
To determine the amount of excess reagent in a chemical reaction, first calculate theoretical values for your reaction to get an estimation of how much of your excess reagent will be left once the limiting reagent is used. Then run the actual experiment and measure!
How to determine stability of a ion or compound in water?
To determine the stability of an ion compound in water: look up the product solubility constant (Ksp) for the compound to be dissolved; write the chemical equation and modify the Ksp equation.
Look at the word equation below: Glucose + Fructose ---> Sucrose + WaterWhich phrase describes the chemical reaction taking place?
Dehydration of simple sugars. :)

What is the word that identifies the chemical on the outer side of a chemical equation?
The reactants are on the left side of a chemical equation and the products are on the right side of the equation. For example, lets look at the chemical equation for photosynthesis. 6CO2 + 6H2O ---> C6H12O6 + 6O2 The reactants are carbon dioxide(CO2) and water(H2O), and the products are glucose(C6H12O6) and oxygen(O2).

What does a complete ionic equation look like?
All ionic substances are written as separate ions in solution
How are reactants and products treated in a chemical reaction?
LOOK AT IT TIL THE END (DON'T THINK NEGATIVE!)For same - use chemical formulasFor difference - use other symbols instead of words to summarize a reaction

What is the chemical equation for nuclear energy?
Nuclear energy is not a chemical process, you don't add chemicals together to get a resultant compound as in chemical processes. When a uranium nucleus fissions, you get two results called the fission products, which are two lighter elements, but there is a range of elements produced, not every fission produces the same result. If you look up 'Fission Products' in wikipedia you will get some idea. See link below.
What does a chemical reaction show?
It shows the preservation of mass and of matter.

You have two solid substances that look the same What measurements would you take and which tests would you perform to determine whether they actually are the same?
- chemical analysis of these substances - determination of some physical properties
What does iron oxide look like after iron has burned?
Because iron oxide is not iron and the chemical/physical properties of substances are different.
What is the chemical equation of radium and oxygen?
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
