AAMC 7R
14 – I know that the passage states that electrolytic techniques did not work well. But there is not further explanation about this technique in the passage. I didn’t know what this technique does – I was thinking about electrolytic cells and how it involves ions so I picked choice D – it does not crystallize well.
18 – SiCl3H when I draw this molecule out, it is a tetrahedral, Si in the centre with 3 Cl and 1 H atom attached so there is a net dipole moment which means that it is poplar – a type of covalent bond. I know that a low BP is mentioned in the Q stem but even covalent bonds have low BP (comparing to ionic bonds)
28 – Can someone go over how this calculation is to be done?
I did A = Ecl = (198)(4.14x10^-3)(1) = approx. 0.8 (choice B)
31 – when determining mass given the density, why are they assuming 1L as the volume?
I know how to do this calculation but I was confused because the volume was not provided in the passage.
39 – I didn’t know what “discharge” means. I thought that as current/charge flows from battery to capacitor, it stores it. So discharge means that current would be let go from the capacitor.
Can someone explain how capacitors work? I am confused.
40 – PE<w done by battery because some energy is lost due to heating of the resistor between the battery and the capacitor.
So, if there was no resistor, would PE = W done by battery?
Do capacitors also heat up in the process of accumulating charge?
65- can someone go over how to set up the formula for this question?
when car A would overtake car B?
Thanks
