With molecular compounds, prefixes are used (mono, di, tri, etc).

Let's break this compound apart (not literally):

dinitrogentrioxide

We know nitrogen is represented as 'N'

We also know that oxygen is represented as 'O'

'Di' means 2, and 'tri' means 3

Let's put everything together now:

N2 (dinitrogen)

O3 (trioxide)

Final answer: N2O3

You always start with metal (left side of the table) and then add non metal (right side) like NaCl
if there is more than one atom then you should mention that too. so in N2O3 you say di for 2 and then Nitrogen and tri for 3 oxygen

Margarita [4]

Answer: 12


Explanation.


This problem was recently posted and deals with the conversion of units,so I give the same answer.


You need to convert the 9 quibs of skvarnick to sleps, to determine how many sleps you have.


The conversion of units is easily undertaken once you build your conversion factors.


Conversion factors are ratios (fractions) equivalent to one, which permits use the identity property of the multiplication to change one unit to a different equivalent one.


Remember that the identity property of multiplication states that any amount multiplied by 1 remains unchanged, i.e.

               a.1=a

Then, build your conversion factor from the definitions given:

  •    12 sleps is equal to 9 quibs.
  •    12 sleps = 9 quibs
  •    in virtue of the division property of equality, you can divide both sides by 12 sleps and get:

                                       1 = 12 sleps /  9 quibs ← conversion factor

Now you can multiply the amount 9 quibs by the conversion factor, which is equal to 1, to find the equivalent amount of sleps:


  •    identity property: 9 quibs = 9 quibs × 1
  •    substitution property: 9 quibs = 9 quibs ×  12 sleps/  9 quibs

You can see that the unit quibs appear in the numerator and the denominator so it cancels out, and the result will be in sleps.


So, all you have to do now is the operations with the numbers:

       9 quibs = (9 ×  12 / 9) sleps = 12 sleps ← answer
