JC Chemistry has always been one of my dreaded topics. Because I could not understand my lessons at college and fail to apply the ideas in my faculty exams, I would constantly discover U’s on my report card. These unhealthy grades in Chemistry made me apprehensive of my options for university. I reached out to FamilyTutor in hopes that they could help me. They related me with Mr. Andrew. He deduced and broke down tough concepts so I could understand them higher and made me follow my applications so I knew how to solve papers. He elevated my confidence and together with his assist, I was ready to score an A in my A-Levels. I can not clarify how thankful I’m to FamilyTutor and Mr.
In the event you need more information on the above, or about choosing JCs or JC topics, or just on methods to effectively examine Math, Physics or Chemistry, do drop by my centre in Bt Batok for a frank, no-obligations dialogue. However do msg me (hp no: 9786 0411) first as I might have classes or conferences. Whether or not you’re a father or mother or a pupil, in case you are critical about training, I stay up for seeing you.
A-levels Chemistry is tough. It’s undoubtedly one of the extra difficult courses in JC and it may be traumatic for a pupil if not treated with the respect it deserves. This subject complexity combined with the immense importance of doing Chemistry courses at A-levels to fulfill prerequisites for any science-associated major makes acing H2 Chemistry an insurmountable process, but is definitely very achievable and the success, actually life-altering!
A solution accommodates a mixture of anhydrous ethanedioc acid, and sodium ethanedioate. 25 cm3 of this resolution required 20.0 cm3 of 0.10 mol/dm3 sodium hydroxide for neutralization using phenolphthalein as indicator, and 28.0 cm3 of 0.02 mol/dm3 of potassium manganate(VII) answer for full oxidation at 60°C in the presence of excess sulfuric acid. Calculate the molarity of the acid and the salt.
