In actual practice a mixture of 80% ammonium nitrate and 20% TNT by weight yields an oxygen balance of +1%, the best properties of all mixtures, and an increase in strength of 30% over TNT. GCSE Chemistry Of all the options above only option listed above, only option B is correct. Previous question Next question Get more help from Chegg. Solid aluminum metal reacts with solid diatomic iodine to form solid Al 2 I 6. chemistry. Oxygen balance (OB, or OB%) is an expression that is used to indicate the degree to which an explosive can be oxidized.If an explosive molecule contains just enough oxygen to form carbon dioxide from carbon, water from hydrogen atoms, all of its sulfur dioxide from sulfur, and all metal oxides from metals with no excess, the molecule is said to have a zero oxygen balance. Solid potassium chlorate, KClO 3, decomposes to form solid potassium chloride and diatomic oxygen gas. 2Al(s)  +    2. Find an answer to your question .Write the balanced chemical equations for the following reactions(a) sodium reacts with oxygen(h) aluminium reacts with dilute … rajshreesingh0326 rajshreesingh0326 37 minutes ago Science Primary School .   Balance Oxygen and Hydrogen Atoms Last . Ca (s) + Cl 2 (g) Ca Cl 2(s) Index To create a balanced equation when aluminium reacts with copper (II) sulphate, provide the correct coefficient for each compound. Hint: This is a simple ratio problem. Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode. 4 Al + 3 O2 → 2 Al2O3 C. Al2O3 → 2 Al + 3 O D.
