Aqua regia is an extremelycorrosivemixture of nitric and hydrochloric acid, used as an etchant, for someanalytical chemistryprocedures, and to refinegold. Aqua regia dissolves gold, platinum, and palladium, but not the othernoble metals. Here's what you need to know to prepare aqua regia and ...
The third step is to prepare the stored raw materials and auxiliary materials, and the 4th step is to manufacture jelly using purified water, jelly powder, and auxiliary materials, using purified water, calcium lactate, nutritional enhancer, sodium ascorbate, citric acid, lactic acid, and malic ...
Plus, they could be fitted with chlorine dioxide for additional disinfection. At Massachusetts Institute of Technology, researchers are even looking at using nanotechnology for desalination. They're experimenting with using sheets of graphene, a form of carbon that's just a single-atom thick, to ...
Combine two tablespoons of baking soda, half a cup of vinegar and 4-5 drops of a dishwashing liquid to prepare the cleaning solution. You can disconnect theshowerhead and soak it in this mixture, or use a ziplock bag to hold the solution and then secure it around the pipe with a rubbe...
Knowing how to purify water for survival is a skill we must all learn today. When disaster strikes, there is a high chance that we won’t have access to bottled water or other forms of ready-madedrinking water. You can prepare for survival by making sure you’ve got bottled water stored...
Explain how you would prepare a 1.135 m solution of KBr in water. Explain how surface area affects the rate of a chemical reaction. Why does a solute dissolve only to a particular extent in water? Why do some substances not dissolve in water at all?Explore...
The term “strategic disconnect” refers to a specific bond in a synthetic target compound. If you have a compound such as cyclohexyl benzene, that you would like to prepare, a promising strategic disconnect would be that sp2-sp3 bond between the phenyl ring and the cyclohexane. That bond cou...
Aquamira’s chlorine dioxide water treatment drops are EPA-registered, are iodine and chlorine-free, safe to use during pregnancy and treat all forms of water. Other advantages to chlorine dioxide is it remains stable, stays good for a long time, does not produce harmful bi-products, and neu...
How many grams of aluminum oxide are produced according to the reaction below if 10.0 g of aluminum are reacted in an excess of oxygen? 4 A l + 3 O 2 2 A l 2 O 3 How many grams of aluminum oxide and carbon are needed to p...
Consider a problem that asks for the weight of sodium sulfate, Na2SO4, required to prepare 250 milliliters (ml) of a 0.5 M solution. The first step is to calculate the number of moles of Na2SO4 required by multiplying the volume of the solution by the molarity: 0.25 liters × 0.5...
