If you decrease the pressure of a fixed amount of gas, its volume will increase.
Answer:
C₄H₁₂ + 7O₂ --> 4CO₂ + 6H₂O
Explanation:
Organic molecules react with O2 to create water and CO2 in combustion processes. C4H12 is an organic molecule that combines with O2 to create water and CO2 as shown in the reactions.
As a result, this is the sole reaction that obeys the general combustion equation.
Answer: Enzymes speed up the reaction rate.
Enzymes are regenerated when the reaction is completed.
Enzymes affect the reaction pathway by forming an enzyme-substrate complex.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Enzymes are biocatalysts and are highly specific in their action. The specificity of enzymes is due to the presence of some specific regions called as active sites. These active sites form weak bonds with substrate molecules.
The specific binding leads to formation of an enzyme substrate complex which accounts for high specificity of enzyme catalyzed reactions.
Once a proper orientation is achieved, substrate molecules react to form products and products leave the enzyme surface as they do not have any affinity towards the enzyme site and are regenerated at the end.
Enzymes work best in optimum temperature and pH range.The enzyme gets denaturated at high pH and temperature.
Answer:
Chemical Change
Explanation:
A chemical change is when something is turned into a new substances.
In this example the wood is being turned into ash.
