What is needed for a chemical reaction to start?
For a chemical reaction to start, firstly, there should be physical contact between the reactants...!!! Also, sometimes: a special temperature or pressure, a catalyst, etc.
What chemical or liquid will have a reaction if it comes in contact with petroleum?
Chlorine in presence of sun light reacts with hydrocarbons present in petroleum.
Is charcoal burning in a grill physical or chemical?
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
What is the difference between boiling points and heating curves?
Boiling something,for example water,is when the liquid HAS to be above 100 degrees Celsius. Heating something is just making it WARMER
Is sour taste a physical or chemical reaction?
Sour taste is a result of a chemical property. Certain chemicals - acids in particular - produce a sour taste when they come in contact with the appropriate taste buds. The chemical interaction of those chemicals with the taste buds yeilds a stimulus of those taste buds that the brain interprets as "sour".
What Chemical reactions between fruit juice and metal?
When metal is brought into contact with fruit juice, the reaction is that of mild corrosion. This is because of the chemical makeup of both substances.
How does an increase in concentration affects rates of chemical reaction?
The rate of chemical reaction increase as the concentration of the chemicals increase. The reason is obvious. There is more opportunity for the atoms to come in contact with each other. This facilitates rate of chemical reaction.
What is a reduced compound?
A reduced compound is a compound that came into contact with another chemical, experienced a chemical reaction, and lost an electron in the reaction. Reduced compounds are often oxidized.
Is there a liquid that will change color when it comes in contact with gold?
I doubt it. Color-change is an indication of a chemical reaction. Gold, however, is generally non-reactive (although highly conductive), which is why it doesn't tarnish or rust. Since I cannot think of another chemical gold reacts easily with, I'm giving a tentative "no" to your question.

How does chemically changed soaking?
Soaking is not a chemical change, unless contact with water results in a chemical reaction - such as adding sodium to water.
What do you think will happen when an acid and metal come in contact with each other?
A chemical reaction is likley to happen
Does salt and water have a chemical reaction when they come in contact?
No. Salt and water becomes a solution, not a new compound.
Why does iron rust?
Iron rusts when it comes in contact with too much water
What causes iron to rust when it comes in contact with water?
Rusting of iron is a chemical reaction of oxidation in the presence of water.
Why does gold turn finger black?
Gold will typically turn black when mixed with a different type of alloy. Bleach and chlorine can turn yellow gold black if it comes in contact with the gold.
What is the chemical reaction that takes place when hydrochloric acid comes in contact with calcite?
CaCO3 + 2HCl --> CaCl2 + CO2 + H2O
