What is relationship between active mass and rate of reaction?
The rate of a chemical reaction increase when the concentration of the reactants increase.
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.
A chemical reaction can be concisely represented by a chemical what?
A chemical reaction can be represented by a chemical equation.
Would a reaction with oxygen be a chemical or physical property?
By the very fact that your have written 'reaction' , it is a chemical property.
Would CoCl2 6H2O cause a chemical reaction?
Cobalt(II) chloride may be a reactant in a chemical reaction.
What temperature change do you think would be required to increase or decrease the reaction time by a factor of 2?
all chemical reaction has to be thought of to be there
How would you speed up a chemical reaction?
increase temperature use a catalyst increase concentration increase surface area of what you are reacting (crushing into a powder)

Would hair bleaching be a chemical reaction?
Bleaching is a chemical reaction.
What effect does changing the concentration on acid have in a chemical reaction invlving a metal such as magnesium?
Increasing the concentration of an acid would increase the rate and vigor of the reaction involving a metal such as magnesium.
What is new substance that is formed during a chemical reaction?
That would be the product of the chemical reaction.
A chemical reaction can be concisely represented by a chemical what?
A chemical reaction can be represented by a chemical equation.
What evidence of chemical reaction would be seen when burning a match?
Burning is a chemical reaction (oxidation).
Which solar phenomenon would NOT be expected to increase with an increase in sunspot number?
granules... :)
Which solar pheomeon would not be expected to increase with an increase in sunspot number?
Granules(:
What is a chemical reaction is it a product or a polymer?
A chemical reaction normally does have a product, and that product in some cases would be a polymer, but it is not true that a chemical reaction is a product or a polymer. It is a specific chemical change.
