What causes molecules to change?
I think this refers to catalysts as these are considered not to be changed by a reaction-- sometimes this true when molecules react on the surface of a catalyst bu sometimes the catalyst does get involved in the chemical reaction- but is regenerated.
What is the name of a surface membrane molecule that causes an immune reaction?
Antigens are surface membrane molecules that cause an immune reaction.
What effects does distilled white vinegar have on antacid tablets?
It has a chemical reaction and the antacid starts to dissolve. or When you do the white vinegar with the antacid tablets together the tube/bottle explodes and causes a chemical reaction.
What is the effect of temperature on rates of reactions?
Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.
What type of energy does a fire use?
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
What causes the reaction rate to decrease as the reaction progresses?
The concentration of the reactants decreases.
Why does the temperature in a chemical reaction rise?
The temperature in a chemical reaction rises because energy is released as bonds are broken and formed between reactant molecules. This excess energy causes the surrounding molecules to move faster and increases the overall temperature of the system.
Where does a chemical reaction occur on a candle?
When a candle burns the wax is reacting with oxygen in the air to give out heat and light.If you give the candle more oxygen then it will burn brighter ... but it will burn out more quickly.The burning of the candle (a chemical reaction) is affected by the number of oxygen molecules around it.So the speed of the chemical reaction is affected by the concentration of oxygen
What determines how molecules are distributed in diffusion?
The concentration gradient is what causes molecules to diffuse.
What chemical reaction causes precipitation?
This is a precipitation reaction.
What causes the reaction rate to decreases as the reaction progresses?
The concentration of the reactants decreases.
What causes the reaction rate to decrease as the reaction progress?
The concentration of the reactants decreases.
Is a microwave an exothermic reaction?
No, a microwave operates by generating electromagnetic radiation which causes water molecules in food to vibrate, generating heat. It is not a chemical reaction so it is not classified as exothermic.
What factors change the rate of chemical reaction?
Adding a catalyst to the process will make the chemical reaction go faster. Also, the temperation, concentration, state of matter and pressure will affect the rate of the chemical reaction.
What is a chemical chain reactionA chemical reaction that causes the next one.(for geoscience Nuclear fission and fusion)?
Share A chemical reaction that causes the next one

Is making crisps a chemical reaction?
Making crisps involves a physical change rather than a chemical reaction. Slicing and frying potatoes causes the water in them to evaporate, which changes their texture and color, but their chemical composition remains the same.
