Group 2A metal oxides are classified as strong bases even though they are not very soluble. The two solubility rules that you will use the most are numbers 1 and 4. You must memorize that all group 1A metal and ammonium compounds are soluble. Also, all nitrates are soluble—look at the end of the compound.

Most recently, my health took a turn for the worse and a full diagnosis is still pending. However, I promised someone that I would post my recipe for Black Raspberry Chocolate Port the next time I posted anything, so that is the main event of this entry, followed by a reprint of an earlier piece on Dutched Cocoa Powder, an essential ingredient in the recipe.
Black Raspberry-Chocolate Port Black raspberries and Dutched chocolate make a great combination for a special port wine. I have long kept this recipe a secret-not because I didn't want to share, but because I wanted something that was "just mine" and when I tasted this I knew it was the one.
Over the years I have had so many requests for this recipe after I inadvertently mentioned it in a blog post that I had finally decided to share it in a future TidBitt entry, mainly to entice more people to subscribe to that now defunct enterprise.
I suppose the time has come. I have made it several ways, the easiest being using farm squeezed and filtered black raspberry juice.
For me, it is also the most expensive since I have to buy the juice from afar and have it shipped to me. The recipe here is my first attempt using frozen black raspberries purchased as a rare find at a local supermarket.
I bought the last five remaining 2-pound bags and made a wine and a port side by side using 5 pounds of berries in each.
The frozen berries were tied into fine-mesh nylon straining bags and left to thaw overnight and half of the next day in sealed primaries. The bags of pulp were also returned to the primaries and the primaries were again sealed.
After about 8 hours I untied each bag, sprinkled 1 teaspoon pectic enzyme into the pulp while stirring and turning the pulp with a long-handled spoon. The bags were retied, left in the primaries and again sealed. The next morning I began making the wine and port.
I won't mention the wine again so as not to confuse anyone.
But it is at this point that the recipe begins. None of the above will be restated below, so you must include this as prelude to the recipe.

Interactions between metals and oxides are key factors to determine the performance of metal/oxide heterojunctions, particularly in nanotechnology, where the miniaturization of devices down to the nanoregime leads to an enormous increase in the density of interfaces.
Thus, r H° = f H°gypsum - f H°anhydrite - f H°water = kJ/mol. ; Exothermic vs. Endothermic If r H° reaction produces a reduction in enthalpy and is exothermic (heat is given up by the rock and gained by the surroundings). If r H° > 0 the reaction produces an increase in enthalpy and is endothermic (heat from the surroundings is consumed by the rock).
Nitrogen (N) and hydrogen (H) react with each other to produce ammonia (NH3).
