What kind of reaction occurs when Br and cyclohexene are mixed?
It's called an addition reaction. Specifically, it's an electrophilic addition reaction.
Where the chemical reaction stake place in a cell?
That really depends on what kind of chemical reactions you are talking about. If you want to know where metabolism takes place (breaking down sugars into energy), that would be in the mitochondria. Synthesis of proteins occurs on the ribosomes. Degradation of proteins occurs in the lysosomes. Synthesis of DNA and RNA occurs in the nucleus. Each part of the cell is involved in very important chemical reactions.
What kind of reaction occurs when hexene decolourises bromine in carbon tetrachloride?
When hexene decolourises bromine in carbon tetrachloride, an addition reaction occurs. The double bond in hexene reacts with bromine, resulting in the formation of a vicinal dibromide. This reaction leads to the loss of the characteristic reddish-brown color of bromine, indicating that the bromine has been consumed in the reaction.
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
What kind of reaction occurs when alkenes decolourises bromine in tetra chloromethane?
The reaction is an addition reaction, where the bromine molecule adds across the double bond of the alkene, forming a colorless dibromoalkane product. This causes the bromine solution to lose its characteristic orange color, resulting in decolorization.
What kind of cell has a negative cell voltage?
An electrolytic cell
What kind of a battery produces an electrical current by the action of 2 plates of different metals in an electrolyte?
The galvanic cell or voltaic cell. Same thing.
What kind of reaction occurs when Br and cyclohexene are mixed?
It's called an addition reaction. Specifically, it's an electrophilic addition reaction.
What type reaction occurs when complex compounds are broken down into simpler substances?
This kind of reaction is called "decomposition".
What kind of reaction occurs to produce energy inside a star?
Nuclear Fusion

What kind of rection occurs when water breaks down producing hydrogen and oxygen?
a decomposition reaction

What kind of reaction is photosynthesis?
Photosynthesis is a chemical reaction that converts carbon dioxide and water into glucose and oxygen using sunlight as an energy source. It is a complex process that occurs in plants, algae, and some bacteria.
What kind of reaction is 2KClO3-2KCL 3O2?
The reaction shown is a decomposition reaction where potassium chlorate (KClO3) breaks down into potassium chloride (KCl) and oxygen gas (O2). This type of reaction occurs when a compound breaks down into simpler substances.
What will happen when potassium and water together what kind of changes?
When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
What is the difference between galvanic and alkaline cells?
It's actually "galvanic" and "alkaline" cells, but no matter. To understand any battery you must first understand the galvanic series, which says that if you take two dissimilar metals and create a conductive path between them, which is called the electrolyte, electricity will flow from one to the other. (The galvanic series was actually invented for sailors so they'd know what metals on their ships would corrode fastest in seawater.) So if you wanted to build a battery that puts out two volts, you'd pick two metals that are two volts apart on the galvanic series. A galvanic cell has two metals submerged in sulfate solutions of themselves (normally copper in copper sulfate and zinc in zinc sulfate), and a conductive pathway connecting the two containers of sulfate solutions. Any other kind of battery has the two metals submerged in the same container of electrolyte. An alkaline battery uses a potassium hydroxide paste as its electrolyte.
