Reaction with water: At first glance, magnesium oxide powder does not appear to react with water. note the key here is DILUTE sulphuric acid to yield the weak redox products. 13. The structure of chloric(I) acid is exactly as shown by its formula, HOCl. Taking magnesium as an example, if the solution is very dilute: (3) M g + 2 H N O 3 M g ( N O 3) 2 + H 2 At moderate concentrations (even with very dilute acid, this occurs to some extent): (4) 3 M g + 8 H N O 3 3 M g ( N O 3) 2 + 2 N O + 4 H 2 O And with concentrated acid: (5) M g + 4 H N O 3 M g ( N O 3) 2 + 2 N O 2 + 2 H 2 O what is observed when dilute sulphuric acid is added to solid sodium web chemical reaction sodium carbonate na 2 co 3 reacts with an acid i e sulphuric acid h 2 so 4 to give salt along with carbon dioxide and water brisk effervescence is observed indicating the copper(II) oxide), 1:37 understand how ions are formed by electron loss or gain, 1:38 know the charges of these ions: metals in Groups 1, 2 and 3, non-metals in Groups 5, 6 and 7, Ag, Cu, Fe, Fe, Pb, Zn, hydrogen (H), hydroxide (OH), ammonium (NH), carbonate (CO), nitrate (NO), sulfate (SO), 1:38b know the charges of these ions: metals in Groups 1, 2 and 3, non-metals in Groups 5, 6 and 7, hydrogen (H), hydroxide (OH), ammonium (NH), carbonate (CO), nitrate (NO), sulfate (SO), 1:39 write formulae for compounds formed between the ions listed in 1:38, 1:40 draw dot-and-cross diagrams to show the formation of ionic compounds by electron transfer, limited to combinations of elements from Groups 1, 2, 3 and 5, 6, 7 only outer electrons need be shown, 1:41 understand ionic bonding in terms of electrostatic attractions, 1:42 understand why compounds with giant ionic lattices have high melting and boiling points, 1:43 Know that ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution, 1:44 know that a covalent bond is formed between atoms by the sharing of a pair of electrons, 1:45 understand covalent bonds in terms of electrostatic attractions, 1:46 understand how to use dot-and-cross diagrams to represent covalent bonds in: diatomic molecules, including hydrogen, oxygen, nitrogen, halogens and hydrogen halides, inorganic molecules including water, ammonia and carbon dioxide, organic molecules containing up to two carbon atoms, including methane, ethane, ethene and those containing halogen atoms, 1:47 explain why substances with a simple molecular structures are gases or liquids, or solids with low melting and boiling points.
