When ammonia combines with water, it forms the aqueous salt ammonium hydroxide. Ammonium is a monovalent cation with formula NH4+. All ammonium salts are soluble in water. Answer and Explanation: Part (a) - Reaction The reaction of magnesium with gaseous ammonia produces s...
2. Why is the saline solution important? Minerals: A mineral is an inorganic solid structure arranged in an orderly and fashioned manner that occurs naturally due to geological processes such as volcanicity and earthquakes. Examples of minerals are gold, diamond, p...
Graphite is insoluble in water. Ithas a high melting point and is a good conductor of electricity, which makes it a suitable material for the electrodes needed in electrolysis . ... These delocalised electrons can all move along together – making graphite a good electrical conductor. Why is ...
Alkali metals are the elements that belong to Group 1 of the periodic table. These elements all have a single electron in their valence shell. This is why they often form ionic compound by transferring this valence elect...
Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H_2O)? Is the melting point of an organic substance affected by the presence of an insoluble compound such as magnesium chloride?...
Why is 5% NaOH insoluble in HCl? Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H_2O)? Why is potassium the most reactive metal? Explain why acid chlorides can be used to prepare amides but amides are not generall...
Explain why 1-hexanol would be soluble or insoluble in water. 1. Why is potassium hydroxide used to dissolve the aluminum? Why not sulfuric acid? 2. What does "amphoteric" mean? Why doesn't the indicator affect the titration results in the standardization of NaOH with standard...
The compound zinc fluoride is a strong electrolyte. Write the reaction when solid zinc fluoride is put into water. A 39.59 gram sample of copper is heated in the presence of excess sulfur. A metal sulfide is formed with a mass of 49.58 g. Determine the empirical formula...
Will the given solid compound dissolve in water? Why or why not? PbO2 Why are the two words "alkaline" and "earth" used to name the group 2 metals? Why is magnesium sulfate used to clean up a lead nitrate spill? Why the elements of group III-A to group VII-A are called p-block...
