(b) How many elements are found in group 4A (or 14)?arrow_forward2.43 g magnesium was completely burnt in oxygen to give magnesium oxide. 2 Mg(s) + O2(g) → 2 MgO(s) (Relative atomic masses: O = 16.0, Mg = 24.3) (a) Draw the electronic diagrams of O2 and MgO, showing electrons in the outermost shell only. (b) (i) How many mole of magnesium was present? (ii) How many mole of oxygen was required to completely react with the amount of magnesium in (i)? (iii) Hence, calculate the amount of oxygen required to completely react with the magnesium. (c) Similarly, calculate the amount of MgO formed.arrow_forward
- (a) Atoms are very small compared to objects on the macroscopic scale. The radius of a nickel atom is 125 pm. What is this value in meters and in centimeters? cm -23 (b) The mass of a single nickel atom is 9.75×10 g. Suppose enough Ni atoms were lined up like beads on a string to span a distance of 31.3 cm (12 inches). How many atoms would be required? atoms What mass in grams of Ni would be used? Could you weigh out this amount of nickel using a typical laboratory balance? (c) Taking the density of nickel metal to be 8.91 g/cm, calculate the mass of metal needed to form a piece of Ni wire with the same length as the distance in b, but with a diameter of 1.00 mm. Hint: The volume of a cylinder is n times its radius squared times its height. (V = nr h) How many nickel atoms does this represent? atomsarrow_forward1c.arrow_forwardIn 1961, scientists agreed that the atomic mass unit (amu)would be defined as the mass of an atom of 12C. Before then,it was defined as the average mass of an atom of naturally occurring oxygen (a mixture of 16O, 17O, and 18O). The current atomic mass of oxygen is 15.9994 amu. (a) Did Avogadro’snumber change after the definition of an amu changed and, if so,in what direction? (b) Did the definition of the mole change?(c) Did the mass of a mole of a substance change? (d) Before1961, was Avogadro’s number 6.021023(when considered tothree significant figures), as it is today?arrow_forward
