Calcium hydroxide react with hydrogen chloride to produce calcium chloride and water (CaCl2 + 2H2O)
An alternative method by which we can overcome this global issue is by harnessing Solar energy.
Discussion:
Fossil fuels cause environmental pollution. This is because they are organic compounds and on combustion, they release air pollutants such as, Carbon monoxide.
As a panacea, the use of solar panels for harnessing Solar energy in a bid to replace energy from fossil fuels will prove to be am effective method by which we can overcome the global issue of pollution caused by burning of fossil fuels.
Solar energy is a clean source of energy as there's no release of harmful air pollutants.

Explanation:
Molarity is defined as number of moles of solute in liter of solution.
Whereas number of moles is equal to mass of given substance divided bu its molar mass.
Since molar mass of HCl is 36.46 g/mol. Therefore, calculate the number of moles of HCl as follows.
=
= 0.686 mol
Hence, molarity of solution will be as follows.
Molarity =
=
= 4.573 mol/L
Thus, we can conclude that molarity of a solution that contains 25 g of HCl in 150 mL of solution is 4.573 mol/L.
Answer: c. oxidation - gain of electrons
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example:
2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example:
3. Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
4. Dehydration reaction is defined as the reaction in which water is lost as product.
5. Hydrolysis reaction is defined as the reaction in which water is used for decomposition.
Example:
Friction would be the answer
