Pumice rocks are formed due to the air that is trapped in
between the rocks, a body of magma spurting out with dissolved gas under
pressure. As the magma cracks through the Earth’s surface, the sudden pressure
drop causes the gas to come out of the solution. The flash of gas form the vent
slices the magma and blows it out as a molten lather. The lather hastily
solidifies as it flies into the air and falls back to Earth as pieces of
pumice.
Answer: A. the chemical change will occur faster in beaker X.
Explanation:
Temperature is one of the factors that affect the rates of chemical reactions. Increase in temperature increases the rates of reaction by increasing the kinetic energy of the reacting particles so that energetic collisions occur and more bonds in the reactants will be broken and; atoms and ions recombine to form new compounds. Beaker X which is at room temperature has higher temperature than beaker Y which is kept in the refrigerator, thus reacting particles in beaker X has more kinetic energy than the ones in beakerA. the chemical change will occur faster in beaker X. Y.
