Answer:
14.57g
Explanation:
Given parameters:
Mass of dish + ball = 15.6g
Initial volume of water in the cylinder = 26.7mL
Final volume of water in the cylinder = 38.9mL
Mass of dish = ?
Unknown
Mass of the ball = ?
Solution;
Since the mass of ball and dish is 15.6g,
Mass of the ball =Mass of ball + dish - mass of the dish
Insert the parameters and solve;
Mass of the ball = 15.6g - 1.03g = 14.57g
Answer:
The correct option is: the precipitation of acidic compounds formed when components of air pollution interact with other components in the air.
Explanation:
<u>Acid rain</u> is a form of precipitation which is usually <u>acidic in nature</u>. The acidic nature of rain is due to the reaction of <u>water molecules with sulfur dioxide, carbon dioxide and nitrogen oxide present in the air, to produce acids.</u>
There are many adverse effects of acid rain, some of them are: effect on water bodies, forests, living organisms, corrosion of structures made of steel and weathering of buildings.
