What kind of reaction takes place when butene decolourises bromine solution?
When butene decolourises bromine solution, it indicates that an addition reaction has occurred. The double bond in butene breaks, and the bromine molecules add across the two carbon atoms that were originally part of the double bond. This forms a colorless dibromide compound, causing the bromine solution to lose its characteristic orange color.
When silver nitrate reacts with hydrochloric acidnwhat type of reaction takes place?
A precipitation reaction takes place when silver nitrate reacts with hydrochloric acid, forming a white precipitate of silver chloride. This reaction can be represented by the chemical equation: AgNO3 + HCl -> AgCl + HNO3.
If you are trying to decide whether a chemical reaction does or does not take place when two substances are mixed what kind of evidence will you look for?
To determine if a chemical reaction takes place when two substances are mixed, you can look for evidence such as color change, formation of precipitate, gas production, change in temperature, and the evolution of light or sound. These observable changes indicate a chemical transformation has occurred.
When two white compounds are mixed in a solution a yellow solid forms What kind of reation has taken place?
A chemical reaction that has taken place is likely a precipitation reaction. The formation of a yellow solid suggests the creation of a new compound that is insoluble in the solution and precipitates out.
This chemical equation is an example of which kind of a reaction?
single replacement
What kind of reaction takes place within the grana?
Light-dependent reactions use the excited electrons produced by the light-capturing events that are used to produce ATP.
What kind of change takes place when you bake bread?
it is a chemical reaction because u cant change it back into dough or flower, eggs, oil etc ingredents that is in it
A reaction is taking place in a beaker and the outside of the beaker goes very cold What kind of reaction is taking place?
The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.

What kind of change takes place when a car door develops rust?
The oxidation of the iron in a car door into iron oxide is a chemical change. The reaction equation is 4 Fe + 3 O2 = 2 Fe2O3
What kind of temperatures are requires for a nuclear fusion reaction to take place?
10,000,000 and up.
What kind of change that takes place when sugar is heated at a short time?
a chemical change take a place
What kind of chemical reaction needs to take place so that methanol can be synthesized?
