<h3>A. an acidic............</h3>
Answer:
Types of chemical weathering
1. Hydrolysis
2. Oxidation
3. Carbonation
4. Acid rain
5. Acids produced by lichens
Explanation:
Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.
Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.
Oxidation : is when oxygen reacts with rocks eg. rust formation
Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.
Answer: The molarity of this solution is 0.159 M.
Explanation:
Given: Mass of solute = 16.3 g
Volume = 1.75 L
Number of moles is defined as the mass of substance divided by its molar mass.
Hence, moles of NaCl (molar mass = 58.44 g/mol) ar calculated as follows.
Molarity is the number of moles of a substance present in a liter of solution.
So, molarity of the given solution is calculated as follows.
Thus, we can conclude that the molarity of this solution is 0.159 M.
