My biggest handicap in chemistry at this moment is learning to convert written chemical reactions to an equation. Like here are some examples of questions I can't do- Potassium nitrate is heated to produce oxygen. I know that KNO3 --> O2 and that's about it Calcium is placed in water and produces calcium hydroxide I can only make out something like Ca + H2O --> Ca(OH)2, probably wrong tho cause can't even balance the oxygens Dilute sulfuric acid is added to magnesium, hydrogen gas is produced H2SO4 + Mg --> H2 is what I can make out, my guess was H2SO4 + Mg--> H2 + MgSO4? Sodium Hydroxide is added to a solution containing H2SO4 How do I know what it produced with the information given? considering I only learned about types of reactions not long ago Manganese dioxide reacts with concentrated hydrochloric acid to produce manganese 2 chloride, chlorine gas and water My stab at it was MgO2 + HCl --> Mg2Cl + Cl2 + H20?
