Achemical reaction that takes in heat is called: exothermic endothermic a phase change

The wilson chamber is used to study: direction, speed, and distance of radioactivity the intensity of radiation the appearance of individual atoms all of the above

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

The identities of substances are the same before and after which type of change
