PLEASE HELP 3.52 grams of potassium iodate are reacted, giving off heat over a water bath containing 450. grams of water. The water bath undergoes a temperature change from 19.9 C to 43.4 C. What is the molar mass (kJ/mol) associated with the formation of potassium iodate?

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Aradio signal from a gps satellite take only about 0.067 seconds to reach a gps reciever. if the speed of light is about 300,000km/s, then approximately how far away is the reciever from from the satellite?
