Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.030 mol of Na is added to 100.00 g of water, the temperature of the resulting solution rises from 25.00°C to 37.90°C. If the specific heat of the solution is 4.18 J/(g · °C), calculate ?H for the reaction, as written.
In the reaction AH3 +H+ = AH4+, AH3 has a dipole moment and AH4+ does not. Predict the number of lone pairs that may exist on A in AH3. Hint: Find more than a single number of lone pairs that work.
