Based on the data in the table, what can we reasonably conclude about the speed of sound through various materials?
The speed of sound is faster in lighter materials,
The speed of sound is higher in liquids than in solids.
The speed of sound is higher in solids than in liquids.
The speed of sound moves slower when atoms are closely packed.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
