When equal moles of an acid and a base are mixed, after reaction the two are compounds are said to be at the . Select one: Indicator point Stoichiometric point Equilibrium point End point

Where are each of the three particles located within the atom?

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)

What conclusion can you draw from this experiment about the components of the black ink?
