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?
