Hey there!

This is not reversible.

We know that this is a chemical change because heat is released (it burned brightly) and it formed a new substance (white powder).

Chemical changes are usually not reversible.

Since this is a chemical change, then this is not reversible.

Hope this helps!

The heat of a reaction may be found with the equation q=mc deltaT.

ANEK [815]

Answer:Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
