Answer:
- motors that run on electricity
- tires that improve gas mileage
Explanation:
The transportation is a major polluter of the air. The big problem with it is that it is necessary for the humans to be able to live and function properly, as the trade is happening through it, thus it is crucial for the economy. In order to stop or reduce the negative impact on the air quality, there are some solutions which can help. The motors that can run on electricity are an excellent method, as the production of electricity is not polluting the are as the fossil fuels are. The only problem is that this type of motors are still very expensive, so once their price is on pair with the combustion motors they can be used. Tires that are able to increase the efficiency of the transportation means can also be useful, as they will be able to reduce the amount of pollutants released into the atmosphere, because the transportation will use less fossil fuels for the same mileage.
Answer:
Explanation:
Under the sector of transportation passenger vehicles are the major contributor to the pollution. Emission from cars and two-wheeler is the leading cause of increasing level of carbon dioxide, sulfur content and other greenhouse gases.

Answer:
0.3M
Explanation:
Molarity of a solution is given by;
M=n/v
Where;
n= number of moles of solute = mass of solute / molar mass
v= volume of solution
n= mass of CaCl2 / molar mass of CaCl2
Mass of CaCl2 = 0.5
Molar mass of CaCl2 = 40 + (2×35.5)
= 111g/mol
n = 0.5/111 = 0.0045mol
volume, v= 15mL = 15/1000 L = 0.015L
Note that molarity is in mole per liter, hence we convert 15mL to L. 1mL=1/1000L
M =0.0045/0.015
M=0.3mol/L
Therefore, the molarity of the solution is 0.3M
