Explanation:
-In NaCl, the sodium ion is the positive one. The chloride ion is the negative one.
-In Ca3P2, the calcuim ion is the positive one. The phosphide ion is the negative one
-In Rb2S, the rubidium ion is the positive one. The sulfide ion is the negative one
-In AlBr3, the aluminum ion is the positive one. The bromide ion is negative
-The K2Se, potassium ion is the positive one. The selenide ion is the negative one
-The BaO, the baruim ion is the positive one. Oxygen ion is the negative one
Nitric acid and calcium hydroxide react to form calcium nitrate and water.
The molecular equation is as follows:
2HNO3 (aq) + Ca(OH)2 (aq) = Ca(NO3)2 (aq) + 2H2O (l)
So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .
Water here seem to be the only real product. It is formed from the OH+ of the hydroxide and the H+ of the acid which combine to form two water molecules.
Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
Answer:
0.01790670606142 we assume you converting between moles fe and gram. you can reveiw more details on each measurement unit: molecular weight of fe or grams the sI base unit for amount of substance is the mole.1 mole is equal to 1 moles fe,or 55.845 grams
Iron becomes rusted especially in damp air but never in a dry air, this is one of the many unique characteristics of iron. Iron is also ductile and malleable. It is found in the seventh group of the periodic table. It has four different and unique crystalline forms and completely dissolves in dilute acids. The two chemical compounds that can be found or made from iron are the bivalent iron also known as ferrous and the trivalent iron or known as ferric compounds.
Carbon has a tendency to form covalent bonds.
