NH3 can react with BF3, forming NH3¾BF3. In this reaction, 1) NH3 acts as a Brønsted base, accepting a proton from the BF3 molecule. 2) NH3 acts as a Lewis base, donating a proton to the BF3 molecule 3) NH3 acts as a Brønsted acid, donating a proton to the BF3 molecule 4) BF3 molecule acts as a Lewis acid, accepting an electron pair from the NH3 molecule to form a coordinate covalent bond 5) BF3 molecule acts as a Lewis base, donating an electron pair to the NH3 molecule to form a coordinate covalent bond
Determine the percent yield for this reaction as N2(g) + 3 H2(g) ? 2 NH3(g)
Compare the pH of a H2CO3 buffer that contains .10 M H2CO3 and .10 M NaHCO3 with another H2cO3 buffer that contains .15 M H2CO3 and .050 M NaHCO3.

If 24.60 mL of a standard 0.3871 M NaOH solution is required to neutralize 43.87 mL of H2SO4, what is the molarity of the acid solution?
The CNOG ion is very unstable and is the reason why the mercuric compound is explosive. On the other hand, mercury cyanate, Hg(NCO)2, is not explosive. The cyanate ion (NCOG) is a stable ion. Use resonance structures and electronegativities to exp..
