Greater rainfall has an greater increase on the rate of chemical weathering. Rain is a form of precipitation.
The correct option is: CH4 + O2 → CO2 + H2O.
In writing chemical equations, the reactants are usually written to the left of the equation of the reaction while the products are written to the right of the reaction. An arrow pointing in the right direction shows the direction of the reaction. In the question given above, methane and oxygen are the reactants while carbon dioxide and water are the products. The options that states the chemical reaction correctly is option 1.
The answer here would be 14.9 %KCl and here is how I can explain why:
33.5g / 225.6g x 100% = 14.9%
<span>you are looking for % of KCl in the solution, you have to add the mass of the KCl and water to get the total mass of the solution
Hope this helps a lot

The correct answer is A: Vapor pressure lowering.
Certain properties in chemistry are called colligative properties. These colligative properties depends on the amount of solute present.
Examples of colligative properties include;
- Vapor pressure lowering
- Freezing point depression
- Boiling point elevation
- Osmotic pressure
When a solute is introduced into water, the vapour pressure of water is lowered.
Hence, when KI is added to a sample of water, vapor pressure lowering occurs.
