Breanne needed to find the percent composition of the compound KClOz The percent of potassium in the compound yes approximately A) 29% 32% 39% 43% Hydrogen peronde is a harmful by product of normal metabolic activity. In order to prevent damage, b, drogen peroxide mus: be

The percent of potassium in the compound KClO₃ = 32%

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements

We determine the molecular mass of KClO₃ then we determine the Ar from K (potassium) and the amount in the compound

MW KClO₃ : 122,55 g/mol

The amount of K in KClO₃ = 1

So %K :

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
