Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. ... This enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
Sounds can travel at approximately 6000 metres per second in some solids and at a quarter of this speed in water. This is because the molecules of solids are more tightly packed together than in liquids and those in liquids are more tightly packed than in gases.
Answer:
Cu2O + H2SO4 ——> CuSO4 + Cu + H2O
Cu2O is oxidized and reduced. It lost an electron in CuSO4 for the 2+ charge, but it gained an electron in Cu to go from the 1+ charge to a neutral charge. This is dismutation (aka disproportionation)

Answer:
A fundamental task of protein is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells. Although rnas are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins
