Answer: Sand and gravel

Explanation:

Sand and gravel have second economic value when it comes to ocean. Sand is used in various types pf activities as it is used for decorative purposes, construction processes and at many other places.

Gravels are small stones that is used as decorative material inside aquariums and it is also used in homes and hotels as a source of decoration and construction.

It has a bit low value as compare to oil that is extracted from ocean.

What are two major advantages of high-yield modern agriculture? what are the major harmful environmental impacts of agriculture?
goldfiish [28.3K]
1.High yield modern agriculture refers to the practice of breeding genetically modified crops or using fertilizer to increase the production yield of planted crops. Two advantage of high yield modern agriculture are:
1. Production of large quantities of planted crops.
2. Ability to select and breed plants with superior qualities.

2. Agriculture have some negative influence on the environment, the major harmful environmental impacts of agriculture are:
a.  Habitat loss: Agricultural practices present great danger to species and ecosystem. This is because, farmed areas serve as habitats for different types of wild plants and animals. Farming the areas makes these living organisms to lose their habitats and these throw the ecosystem into imbalance.
b. Soil erosion and degradation: When natural vegetation are converted into agricultural lands, the breaking up of the soil leads to erosion, which wash away the top soil and the nutrients that are embedded in it. 
c. Pollution: The chemicals that are used during farming operations, such as fertilizers, pesticides, etc. cause pollution of the air and the surrounding waters.
3. Soil erosion is the process by which the top layers of soils are carried away by agents such as wind and water. The biggest negative effect of soil erosion is the loss of top soil. The top soil is the part of the soil that contain most of the nutrients that plants use to grow. When this part of the soil is lost, the soil usually becomes non fertile. Soil erosion can also lead to water pollution. When soils are eroded from the farm lands and carried to the surrounding waters, the waters will be polluted by the chemicals such as pesticides, herbicides and fertilizers, which are had been used on the soils. This can lead to the death of the animals that are living in the waters.

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction: Fe + O2
Ber [7]

ANSWER

The correct answer is A

<u>EXPLANATION</u>

From the equation Fe + O_2 \rightarrow Fe_2O_3


<u>L.H.S.</u>               


Fe = 1                        

O  =2      

                 

<u> R.H.S</u>

Fe =2


O  =3

Now, let try to balance the oxygen atoms first,

To do this, we know the Least Common Multiples of 2 and 3 is 6


To get 6 atoms of oxygen at L.H.S  multiply 2 by 3 and on the R.H.S, multiply 3 by 2



L.H.S.                        

O=2\times3=6      


R.H.S

O=3\times2=6  


This means that, 3 should be in front of O_2 at the L.H.S and 2 should come before Fe_2O_3 in the R.H.S of the equation


Now, we have


L.H.S.                        


Fe = 1                          

O  =  6                        

<u>R.H.S</u>

Fe =4

O  =6

The equation is still not balanced since Fe is not balance

 

The Least Common Multiple of  1 and 4 is 4

Which means that we need to multiply 1 by 4 at the L.H.S and 4 by 1 at the R.H.S



L.H.S.                        

Fe=1\times4=4      


R.H.S

Fe=4\times1=4  


We now, have



<u>L.H.S.   </u>                    

Fe= 4                          

O=6                        


<u>R.H.S</u>

Fe =4

O=6

Hence the balanced equation is

4Fe +3O_2\rightarrow 2Fe_2O_3
