To begin with, as Delta H = variation in enthalpy is >0 , it means rxn is endothermic.
The rule says: Delta U = Delta H + W = 186 -179 = 7 kJ.
Where Delta U is variation in internal energy and W is the work done.
Because no one else can have the same fingerprint as another person. Each fingerprint is individual and unique.
Answer:
evaporation and distilation
Explanation:
Answer:
An external stimuli is a stimulus that comes from outside an organism and causes a reaction.An internal stimuli is a stimulus that comes from inside an organism.
