    It's because the ray passes twice through the layer of fat before it's intensity is detected. So the expression is more like: 0.018 x (e^-48 x x*10-2)2 If you solve it this way you will get the same answer

    Not really. You just have to memorise them as they are. There's no concept. I hope you remember the colours of Cu on adding NH3. They will help you memorise the colours of two reactions and that's that. Otherwise it's all memorisation.

    You don't need to revise all of them.Just go with cobalt and copper.

    learn the formula I=nhf where I is the current, n is the no. of photons and f is the frequency. You can also write it as I=nh3x108/λ so that means I is inversely proportional to the wavelength. So if n (intensity or no.) is constant and wavelength is reduced, the current will increase.

    its okay :) okay let me explain We have one goal and that is MAKING 2 MOLES OF SO3. let's start from the oxidation reaction to make 2 moles of SO3 you need 2 moles of SO2 right? So let's say we are given 1 mole of O2 and one mole of S and we make one mole of SO2 and we get an energy change of...

    For part 1, the photoelectric effect will not help because it supports the particulate nature of light. Look into the wave nature instead which is very different. According to that theory, there is SUFFICIENT TIME DELAY between electron emmision and light incidence. This is because electrons...

    When nuclei are placed in magnetic field, they precess at Larmor frequency and emit r.f. pulses. This frequency depends on strength of magnetic field as w = Bγ. Different rf pulse frequency emitted allow nuclei to be located. Changing field also allows position of detection to be changed.

    cuz the reaction is like 2SO2 + O" -> 2SO3 so that means the enthalpy change already shows 2 moles being made n in oxidation the same no. of moles are made. But in SO2 formation, only one mole is made in the reaction. But in oxidation of SO2, 2 moles are used. So to equal the moles, it was...
