Answer: Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements.
You find the number of protons in an atom by looking at the periodic table.
1) Find your element.
2) Locate The atomic number of your element
3) The Atomic Number is also the number of protons.
Usually, the atomic number is on the on the top of the atomic symbol.

Parsec is a unit of distance (as stated 1 Parsec = 3.26 light years, wihch is 3.26 times the distance run by light in one year).
That distance is:
1 parsec = 3.26 mi× 186,000 mi/s × 3600 s/h × 24 h/day × 365 day/ year × 1 year = 19,122,168,960,000.mi.
So, the question of <span>how many parsecs it takes for light to reach Mars from Earth does not make sense because parsecs is not a unit of time.

</span><span>You can calculate how many parsecs is equivalent to the distance between Mars and Earth, 60,000,000 km. For this you can first calculate the equivalence of which you do in this way:
</span><span>
</span><span>
</span><span>60,000,000 km × 0,621 mi/km × 1 parsec / ( 19,122,168,960,000 mi) = 1.94E-6 parsecs.
