Which of these instruments can be used to predict a thunderstorm? wind vane rain gauge radiosonde thermometer

The correct answer is radiosonde.  

A radiosonde refers to a battery-oriented telemetry apparatus taken into the atmosphere generally with the help of a weather balloon, which helps in the prediction of several atmospheric parameters and transfers them by radio to a ground receiver. The current radiosondes calculate or predict various elements like pressure, attitude, relative humidity, temperature, cosmic ray, wind, and other elements. Thus, it can be a helpful instrument for the prediction of a thunderstorm.  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
