In a garden with trees and shrubs, green and pink katydids were observed. Over time, birds started feeding on the katydids. Whic
densk [106]

The right options are;  

A.The population of pink katydids will decrease.

B.The population of green katydids will decrease.

What will eventually happen to the population of the katydids is that the population of both the pink and green katydids will decrease. The predators which are the birds that feeds on the katydids (prey) will negatively influence the size of the prey populations by reducing them.

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
