    What you guys dont understand is that it cant be D because Ag and Cu are right beside each other. The voltage produced is very minimal. Like Mg and Ag say ja kar koi 2 V produce hoti hai.

    Yes they do flow. Anode --> Cu --> Cu2+ + 2e On cathode --> Cu 2+ 2e --> Cu I've seen the diagram in books and it had a bulb which lighted :p

    No bro. Cu and Ag are besides each other. The voltage produced is VERY less. It was (A). 100% Confirmed :p

    I wrote glucose because when you form the carbohydrate by adding two diol monomers also known as glucose monomers. When you hydrolise the card, you get glucose just like you hydrolise protein polymer and got Amino acid monomer.

    It said 17 tonnes. A tonne is 10^6 grams.

    Combine the Equations . You get the mol ratio of NH3 to mol ratio of fertiliser as 2:1. Mass of NH3 = 17 tonnes Moles of 17 tonnes of NH3 = 17 x 10^6 / 17 = 1 000 000 Moles of fertilisers = 500000 mol Mass = mol x MR 500000 x 80 = 40 tonnes

    Pretty sure two half-lives thin :p You had to divide them the opposite way. You get 1/4 that way which is (1/2)^2 So 2 half lives. Half life was 5700. 5700 x 2 = 11400
