    Chemistry: Post your doubts here!

    Q8: It's D. First IE of calcium = 590 Second IE of calcium = 1150 To convert solid Ca into gas you need 177 kJmol-1 energy, and then to convert it to 2+ ions you need 590+1150 energy. Then for hydrating the ions the energy change is 1565kjmol-1. So total energy change = 177+590+1150-1565 = +352...

    Nearer the heart, the vessels are wider and farthest they are, the narrowest As we move from aorta to capillaries, (the oxygenated pathway), the diameter of vessels decrease, the aorta is the largest and capillaries are the tiny vessels with very narrow lumen (for blood to diffuse more quickly...

    A level Biology: Post your doubts here!

    You need to identify the stage the cell is under and then arrange the stages. 1. Centromeres divide before chromatids move apart, i.e. before Anaphase 2. that's Anaphase so 2 shall come after 1 3. Chromosomes line up along equator during Metaphase so the sequence must be 3 then 1 then 2 4...

    First we write down the balanced equation so we can know the ratio of moles of calcium carbonate to moles of hydrochloric acid: CaCO3 + 2 HCl >>> CaCl2 +CO2 + H2O Now find the number of moles of Hcl: 36 cm3 is 0.036 dm3 so no. of mol = 0.036 x 0.5 = 0.018 mol since 2 mol of hcl react...
