(ii) chlorine gas formed at the anode 2Cl – (aq) – 2e – ==> Cl 2(g) (an oxidation electrode reaction - electron loss at anode) or 2Cl – (aq) ==> Cl 2(g) + 2e – This is the basis for the industrial production of calcium metal (b) Molten anhydrous zinc chloride
Ammonium chloride is made up of NH 4 + ions from the base ( NH 3) and Cl − anions from the acid ( HCl). HCl (aq) + NH 3 (aq) → NH 4 Cl (aq) You should notice that in the first two examples, the base contained OH − ions, and therefore the products were a salt …
Ca (s) + 2H 2 O (l) ——> Ca (OH) 2 (aq) + H 2 (g) In the following demonstration, a chunk of calcium metal is dropped into a beaker of distilled water. After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide.
Lime is used in the production of metals. It is used during the manufacture of steel to remove unwanted sand, or silicon dioxide (SiO 2 ), present in iron ore: The product formed in this reaction, calcium silie (CaSiO 3 ), is called slag. Another important use of lime is in pollution control.
28/12/2015· Nitrogen is a diatomic molecular compound, making it N2 . Since calcium nitride is an ionic compound, by evaluating its constituent ions we can determine its formula. The calcium ion is a 2+ ion, or Ca2+. The nitride ion is a 3- ion, or N3−. As such, to balance the charges we require 3x calcium ions for every 2x nitride ions, or Ca3N2.
10/3/2002· E-MORB, enriched MORB, is relatively undepleted in incompatible elements. E_MORB was once thought to be typical of hot spots along mid-ocean ridges, such as Iceland, but is now known to be present in many loions along mid-ocean ridges. N-MORB

As that product forms, it emerges, or precipitates, from the solution as a solid. This process is called precipitation, such a reaction is called a precipitation reaction, and the solid is called the precipitate. For example, when water solutions of calcium nitrate
View this answer. When calcium metal and hydrochloric acid react, they form calcium chloride and hydrogen gas. In this reaction, the calcium metal replaces the See full answer below.
26/7/2020· calcium + chlorine → calcium chloride In all of these reactions, the metal atoms give electrons to the non-metal atoms.
Calcium carbonate (CaCO 3) is a metal carbonate compound and reacts with hydrochloric acid (HCl) to produce carbon dioxide (CO 2), calcium chloride (CaCl 2) and water. You can see, carbon dioxide gas is bubbled through the solution.

Synthesis and reactions. Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: Ca 3 …
Solution : Common salt is an ionic compound containing ionic bonds whereas cane sugar is a covalent compound containing covalent bonds. Since, ionic compounds conduct electricity and covalent compounds do not, hence common salt is a good conductor of electricity and cane sugar is a non-conductor of electricity.
Nitric acid and calcium carbonate produce carbon dioxide, water and calcium nitrate. The reaction is 2 HNO3 + CaCO3 = CO2 + Ca(NO3)2 + H2O. How can you test what happens when calcium carbonate
