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
Why is mass energy not apparent for chemical reactions?
According to Einstein's equation, E = mc2, any time there is energy released by a chemical reaction there must be a change in mass. The factor, c2,is such a hugh factor that the mass change is so small that it is not measurable by our balances.
What hypothesis for a method in investigating a factor that affects the temperature of a chemical reaction?
The rise in temperature is affected by the amount of anhydrous sodium carbohydrate added to 20ml of water
Which factor affects the reaction rate by altering the reaction path?
catalyst
Which substance is considered to be a factor affecting Earth's ozone layer?
chlorofluorocarbons
Which factor badly affects the Taj Mahal?
acid rain is one of the most affecting factor to the beauty of taj mahal as a chemical reaction between acid rain and marble deteriorates the marble
What is the most important factor affecting the formation of chemical bonds?

A factor that speeds up a chemical reaction?
catalysts
What is a factor that speeds up a chemical reaction?
Heat or Catalysts
A factor that slows down a chemical reaction?
A decrease in temperature.
One of 5 things have to happen for a chemical reaction to take place?
the requiredactivation energy is the basic factor for a reaction to start.
One thing that is not a factor in determining critical mass is?

Why is light an important factor in all chemical reactions?
Light usually provides enough energy for exchange of electrons and carry out the chemical reaction.
What factor does affect the most rate of reaction?
Factors affecting the rate of reaction 1. Temperature 2. Catalyst 3. Concentrations of the reactants 4. Nature of the reactants 5. Surface area of the reactants
Does air rust iron?
Rusting is a chemical reaction - an oxydation; the essential factor for iron rusting is oxygen.
What is the difference between the present value of an investment and its cost?
pressure is dependent on temperature pressure is a mere important factor that affect chemical reaction temperature acts on chemical reaction faster than pressure
