The answer I believe is B. Erosion
Explanation:
Just sounds better than all the other choices.
The answer to this question would be: covalent bond
Silicon dioxide or SiO2 is made of silicon which is a metalloid and oxygen which is a gas. The bond that the molecule made is a polar covalent bond because silicon is not a real metal. Silicon dioxide is a polymorph that has many different kinds of crystal form.
The level in the beaker will increase because the volumes of the spheres will also be added to the volume of the water. First, we must determine the volume of each sphere. For this, we will use:
density = mass / volume
We can check the density of both aluminum and iron in literature, and given the mass, we may obtain the volume.
Aluminum:
Density = 2.70 g/ml
Mass = 20.4 g
Volume = 20.4 / 2.7 = 7.56 ml
Iron:
Density = 7.87 g/ml
Mass = 49.4 g
Volume = 49.4 / 7.87 = 6.28 ml
Now, we add these volumes to the volume of water present:
75.2 + 6.28 + 7.56 = 89.04
The new level will be 89.0 ml
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.
