Answer:
It is an example of Arrhenius acid-base reaction.
Explanation:
- In this reaction, water acts as an Arrhenius base because it consumes a proton from sulfuric acid.
- In this reaction, sulfuric acid acts as an Arrhenius acid because it donates a proton to water.
- Lone pair on oxygen atom in water is used to bind the proton obtained from sulfuric acid.
- Proton attached to -OH group in sulfuric acid is being donated because it is loosely bounded to oxygen atom due to high polarity of O-H bond.
- Reaction:
- Mechanism has been shown below.
from google, so I think the answer to that question is the second one
A catalyst is something that is used to lower the activation energy of a reaction, that is later regenerated by the reaction (but the equilibrium isn't altered). In this case, an enzyme is an organic (protein) catalyst, so that's your answer.
Answer: 70 percent
About 97 percent of Earth's water is in the ocean.
The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our ocean. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps.
