[@bayahlengwa2428]

Last year I got level 1 in chemistry grade10 term3... Believe it or not this year in grade 11 term 3 I got level 7 all thanks to you mam❤️❤️.. You really do make a difference ❤️🌹

Hi Mam, I'm in grade 10 and in term 3 and this such a big help to me thank you

[@Mawethu-Luvuno]

Just when I needed it thank you so much.❤

[@KgaoMaleka]

Hi mam if I define Heat of reaction or Enthalpy as an energy absorbed or released per mole in a chemical reaction ... Then if I define Endothermic reaction and Exothermic reaction in this way will I get full marks?? Endothermic reaction absorbeds energy and it's Enthalpy it's Greater than zero as for endothermic reaction are that releases energy and it's Enthalpy it's less than zero will they be Worthy full marks??
