What are 3 conditions that necessary for a reaction to occur?
There are many factors that affect the occurance of a chemical reaction. If the reaction you are using has any buffer or catalyst than you should be selective in that keeping in mind your reactants and product. The temperature required for any particular reaction to occur should also be kept in mind.
What must be produced for a double displacement reaction to occur?
A precipitate, water, or a gas must be produced for a double displacement reaction to occur.
Why is the boiling point of water a physical change?
It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
Why do chemical reactions in your metabolism happen in water?

Adding a catalyst increases reaction speed by?
Catalysts lower the activation energy required for a chemical reaction. Activation energy refers to the mininum amount of energy that the reactant particles must possess so that effective collisions between them (hence a chemical reaction) can occur.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.

Can a chemical reaction occur without any new substanced?
No, in order for a chemical reaction to take place, a new chemical substance must be formed.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
What kind of change must occur for an element to be removed from its compound?
a chemical change
Is burn a physical change?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
What is the only way a chemical change can occur?
A new compound must be obtained.
A catalyst increases the rate of a chemical reaction by changing which of the following conditions?
A catalyst can speed up the rate of a given chemical reaction by lowering the activation energy required for the reaction to occur. However, the catalyst does not change the total free energy from reactants to products.
Is hardness a change in chemical property?
There are many different possible property changes in a chemical change. You must post the specific reaction for anyone to tell you exactly.
When does chemical equilibrium occur?
When reactants and the products that are also contributing to a chemical reaction show no sign over change over time, chemical equilibrium has taken place. Chemical equilibrium can be called a "steady state reaction". It must be noted, however, that just because nothing has changed, it doesn't necessarily indicate that the interaction has stopped.
What are the two attributes of a catalyst?
A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
What makes chemical reaction spontaneous?
Stability of the products as compare to stability of reactants.
