1000 m = 1 km
so if you have 6 km you have 1000×6= 6000m
So you live 6000m from school

Answer:  6,000 m .  (or, write as:  6,000 meters).
_______________________________________________________
Explanation:
_________________________________________________
Note the exact conversion:  1 km = 1000 m .
______________________________________________________
Note:  "km" is an abbreviated form of "kilometer(s)".
              "m" is an abbreviated form of "meter(s)".
______________________________________________________
Here is one way to solve, using a method called "dimensional analysis":
_______________________________________________________
  Given:  6 km ;  convert to  "m"  ; 
______________________________________________________
         →  6 km =  <span>   ?  </span>  m  ;
___________________________________________________
        →  6 km * \frac{1000  m}{1 km}  =   ?    m ;
___________________________________________________
        →  On the "left-hand side" of the equation, the units of  "km"                                  "cancel out" to "1" ;  and we are left with:
_______________________________________________
        →  6  * \frac{1000 m}{1   =    ?  m ;
_______________________________________________
       .→  6  * 1000 m   =  <span> <span>   ?</span></span>   m  ;
_______________________________________________
                            →   =  6,000 m ; or write as:  6,000 meters .

What is the sequence of coefficients that will balance the following decomposition reaction of dihydrogen monosulfide? H₂S ----&
RUDIKE [14]

8 S

In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:

Answer:

Explanation:

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.  

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:

Left side: 2 H and 1 S

Right side: 2 H and 8 S

In this case you must start balancing the sulfur to have 8 on each side of the reaction. So:

8 H₂S → H₂ + S₈

Now the amount of elements on each side of the equation:

Left side: 16 H and 8  

Right side: 2 H and 8 S

Now you need to start balancing the hydrogen to get the same amount from each side of the reaction. So:

8 H₂S → 8 H₂ + S₈

Now the amount of elements on each side of the equation:

Left side: 16 H and 8  

Right side: 16 H and 8 S

<u><em>The balanced reaction is:</em></u>

<u><em>8 H₂S → 8 H₂ + S₈</em></u>

Methane burns in oxygen to produce carbon dioxide and water. Which of the following represents a preliminary, unbalanced equatio
german

The correct option is: CH4 + O2 → CO2 + H2O.

In writing chemical equations, the reactants are usually written to the left of the equation of the reaction while the products are written to the right of the reaction. An arrow pointing in the right direction shows the direction of the reaction. In the question given above, methane and oxygen are the reactants while carbon dioxide and water are the products. The options that states the chemical reaction correctly is option 1.
