<span>A chemical reaction in which compounds break up into simpler constituents is D. decomposition. This should be an obvious answer - when something decomposes, it falls apart and creates smaller parts of the original thing. The same thing goes with the compounds - they will fall apart into constituents that are way simpler than them. </span>
The density of a pure gold is 19.32g/cm3 if the volume is 4.30 cm3 then we can calculate the mass using the formula mass=density x volume mass=19.32*4.30 mass=83.076g
