Put the following metric units in order from smallest to largest: pl, ml, dl, kl.

Explanation:

These are multiples and submultiples of the unit liters.

                          pL, mL, dL and kL

                          pL<mL< dL< kL

Units can be expressed in form of multiples and submultiples form using the following prefixes:

  Note: submultiples are lower than multiples:

            submultiples              10⁻¹            deci(d)

                                               10⁻³            milli(m)

                                               10⁻¹²            pico(p)

        multiples           10                  deca(da)

                                  10³                  kilo(k)

explanation:

detials on each model with digrams

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
