There are many ways to do this. A Catalyst can often get a reaction going and speed it up, for example magnesium with the decomposition of Hydrogen Peroxide. Another way is to suddenly input a large amount of energy, such as a shock-wave, to start a reaction. Many explosives work this way.
What else can I help you with?
What triggers the chemical reaction and gets it going or photosynthesis?
Sunlight - uv
Is bread going brown in the toaster a chemical reaction?
Yes, it is a chemical reaction.
Is paper going through a shredder a chemical reaction?
no!
What happens during a chemical reaction that involves an acid and a base?
it gets a liquid out
Why does a change in temperature indicate that a chemical reaction may occur?
Because a chemical reaction has different sign's. And heat is one. But if the temperature is dropping then it is not going through a chemical change.
What is difference between released chemical energy and absorbed chemical energy?
When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.
When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
What is an element or compound that enters into a chemical reaction?
A reactant is a substance that enters into a chemical reaction and is transformed into a new product. It is present at the start of the reaction and gets consumed during the process.
Differentiate between the reactants and the products in the reaction?
A reactant is an "ingredient" in a chemical reaction; it is a substance you have at the beginning of a reaction. A product is what gets produced in a chemical reaction; it is a new substance you did not have before. Reactants yield products.
How does a fire start?
when a flammable chemical such as oil (ancient tree) gets heated up to much it acts as a chemical reaction it catches on fire
What happen when mix baking soda and vinegar?
it gets messy and fizzes and yes dont try it in doors
What happens to energy during a chemical reaction?
During a chemical reaction, energy is either absorbed or released. If energy is released, it is usually in the form of heat. If energy is absorbed, the reaction requires an external energy source to proceed.
