which is more precise measurement of mass a number that is rounded to the nearest milligram or a number that is rounded to the nearest microgram? Explain​

Variables,control,conclusion and finally scientific theory

The net force is 100

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
