How do I convert 7.80 into scientific notation?​

Biology

statuscvo [17]3 years ago

To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.

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

What are the two ways that eubacteria can reproduce?
tresset_1 [31]

The two ways through which Eubacteria can reproduce are as follows:

  • Binary fission and Conjugation.

Thus, the correct option for this question is C.

<h3>What is Eubacteria?</h3>

Eubacteria may be defined as a prokaryotic microorganism that primarily consists of a single cell that lacks a nucleus and contains DNA in a single circular chromosome. It also lacks other membrane-bound cell organelles.

During the process of binary fission, Eubacteria divide into two separate daughter cells through mitosis. While during the process of conjugation, two Eubacteria cells of the same or different species connect using the pili and exchange their genetic material.

Conjugation is partially considered a type of sexual mode.

Therefore, binary fission and conjugation are the two methods through which eubacteria can reproduce. Thus, the correct option for this question is C.

To learn more about Eubacteria, refer to the link:
