Water is important in chemical weathering because _______

Chemistry
1 answer:
saw5 [17]2 years ago
7 0

Answer:

Water plays a very important role in chemical weathering in three different ways. First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Finally, the water can break up minerals through hydrolysis. The most common group of minerals, the silicates, is decomposed by this process.

Complete the mechanism for the acid-catalyzed hydrolysis of the epoxide in alcohol by adding any missing atoms, bonds, charges,
Sauron [17]

Answer:

See explanation below

Explanation:

You are missing the structure, therefore, I will do an example with one that I found on another place to try to explain.

This acid mechanism always involves carbocations, and positive charges, never negative because we are in acidic mediums.

In the first step, the lone pairs of the oxigen from the epoxide, substract one hydrogen of the reactant.

Second step, the lone pairs of the oxygen from the reactant, do a nucleophylic attack to the carbon of the epoxide. In this case, it will do it to the most substitued carbon.

Then, in the third step by acid base equilibrium, the hydrogen from the reactant that attacked, is substracted from the molecule by a molecule of water (We are in acid medium, therefore, there is traces of water) and the final structure is formed.

I need help ASAP please
Andrej [43]

525L

Explanation:

Given parameters:

Volume to Temperature ratio = 1.75

Temperature = 300k

Unknown:

Volume of the gas = ?

Solution:

We must carefully analyze and comprehend the detailed description of this experiment:

 It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.

This implies that the pressure in the vessel is constant

This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.

 Mathematically;

                 \frac{V1}{T1}  = \frac{V2}{T2}

V and T are the volume and temperature

 Now we can solve the given problem;

           \frac{V}{T}  = 1.75

Since temperature is given as 300K

 Input the variables:

           \frac{V}{300}  =  1.75

          V = 1.75 x 300 = 525L
