Which of the following would result in the magnesium ribbon 'dissappearing' in less than 45 seconds? *Warming the acid
*Using 2g magnesium ribbon
*Stirring the mixture
*Adding water to the acid

BTW:- The acid is sulfuric acid

your should probably be warming the acid

Explanation:

because when you are it is disappearing

Warming the acid

Explanation:

This is because when the acid is heated, the particle of the acid gain more energy (kinetic to be more precise) causing more collisions to occur, colliding even more with the particles of the magnesium ribbon. This increases the rate of disappearance of the magnesium ribbon.

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
