today chemistry lesson is boring. what i can say is the teacher really cant make it. ): For example: what would a chemist use to measure exactly 25.5cm cube of dilute hydrochloric acid?a) burette b) beaker c)measuring cylinder d) pipette answer should be (a) right? she said (d). then still nevermind. next question.given you (i) measuring cylinder (ii) beaker (iii) test tube (iv) burette (v) pipette select the best apparatus to perform each tasks.(a) boiling 40cm cube of non-flammable liquid(b) holding 5cm cube of water for heating(a) answer should be beaker. she said test tube.(b) answer should be test tube. she said beaker. i find it not right so i question the teacher. she wrote my answer on the whiteboard. thinking that, that was her answer. and she goes 'yayaya, you are wrong because test tube can only hold 20cm cube of liquid therfore (a) answer is beaker.' and i was like -.-" that was my answer..
