Use the information in the table to explain your answer.3(b)Zinc chloride can be made by reacting excess zinc with hydrochloric acid.Suggest how the excess zinc can be removed from the reaction mixture.……[1](c) Zinc can be obtained from molten zinc chloride by electrolysis.(i) What is...
Non-metals usually gain electrons when reacting with other compounds, forming covalent bonds, due to their features. The anionic dopants have a strong influence on the VB among the non-metals. Carbon, nitrogen, fluorine, sulphur, and iodine are non-metal dopants. Non-metals have the following ...

(d) Iron has a tendency to get rusted in atmosphere by reacting with oxygen and water vapours present in air. In order to check rusting, iron articles are generally coated with zinc. This process is known as galvanization. This brings us to the end of the important questions and an...
All metals that are found above hydrogen in the activity series liberate H2 gas upon reacting with dilute HCl or dilute H2SO4. Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower from their salt solutions. Higher ranking metals requir...
Dilute hydrochloric acid reacts with magnesium liberating hydrogen, but the same is not liberated when the acid reacts with copper. View Solution Generally metals react with acids to give salt and hydrogen gas. Which of the following acids does not give hydrogen gas on reacting with metals (exc...
With a conservative estimate of 1 gram of solid reacting in a 300 mL vessel for 30 min, the equivalent loading rate is 160 kg/m3/day, or 100 times more efficient than the anaerobic digestion solids loading rate of 1.6–4.8 kg VSS/m3/day (Metcalf and Eddy, 2013). This disparity and ...
is immiscible with the oleaginous liquid and forms a separate liquid phase therefrom and a solubilizing component which is capable of reacting with the metallic component to render it soluble or dispersible in the carrier liquid, and then separating the carrier liquid phase from the oleaginous liquid...
The acid is then converted into the corresponding metal salt by reacting with an appropriate precursor compound constituted e.g. by a metal salt, such as a silver salt or a copper salt. The corresponding metal salt can also be directly used for producing the membrane. The reactions which ...
Nitrates can be prepared by reacting the corresponding oxides, hydroxides and carbonates with nitric acid. Nitrates are soluble in water. On heating, beryllium nitrate forms nitrite, and other nitrates yield oxide, liberating brown fumes of nitrogen dioxide. 2M(NO3)2 → 2MO + 4 NO2 + O2 Hali...
