    well all eminem fans write 'proof' even when they mean prove :p i did many questions like that and only this question has this bullshit. btw the logic of removing water is best joke of the day:D

    doesn't acid have water? will it evaporate the water in it. man think about it. it will add more H+ ions so our results will be inaccurate. CIE is not god, neither are our teachers. my chemistry teachers say what they read in books, especially when he has no answer to it. i read the question...

    totally rubbish. f*ck logic. makes no sense. i wont believe it unless someone gives me convincing explanation.

    so please tell me why u need to rinse with acid/alkali? to get inaccurate results. if u reuse something u want it to be like new if u wash it. so if u wash it by acid/alkali then it will be like used one then what is purpose of rinsing? a new one will be neutral so make it neutral by washing it...

    this will answer all ur questions zainabkhann it has list of variable their symbol, tips for drawing graphs, for revision and much more. i downloaded it from cambridge student site

    if u increase temperature the speed will always increase but production depends. if it is exothermic reaction then it prefers less heat as it producec head itself. but the backward reaction is endothermic which prefers more temperature. so u have created conditions which favours...

    i guess u r doing chemistry for the first time. do u have any reason to support ur answer. read my response:

    with tap water then with distilled water. if u use alkali or acid, it will affect final result as alkali will increase concentration of alkali in next reaction and if u wash with acid some of acid will remain and it will react will alkali ths decreasing concentration of alkali even before u...

    do u know Energy=power*time and power=Voltage*Current. so more current and voltage will result in more power which means more energy. more electrical energy means more light energy from bulb of more heat energy from heater and more kinetic energy from motor. more voltage or current, more energy...

    for nuclear i already know so much that i did not do it in class and just started the past papers of that chapter. i had interest in physics from the time i was a kid so i watched recreational physics videos and know most of physics due to them. thats why i m gud at physics. tell me if u need help.

    i will do bistable and astable circuit from collins book. maybe it has them, if it will be difficult then we will leave the question. Nuclear physics has come in MCQs and paper 2 many times.

    in parallel voltage in every connection has full voltage(battery voltage) thus maximum current than in series. although less current flows through that connection where the resistance is high. if u attach 5 bulbs to 5 volts battery in series they will be very dim as each will get just 1 volt and...

    most of the time we get wrong answer because we start to do question as soon as we read it. for both relative velocity and permutation/combination u must read everything clearly, then create a strategy in ur mind, highlight key words such as 'wind APPEARED to be blowing FROM east' then draw a...

    as they are vertical,, the x-component of position vector will be the same. i dont remember that question exactly, it was i guess 20sin53=16km/h and 26sin22.6=10km/h 16t km= 104-10tkm solve for t.

    no ur wrong, u cant find the distance like that, u r subtracting their distance from different locations. as they are vertical, we need to take their y-component find their difference then multiply by 4(t)
