(a)
Interpretation:
Empirical formula of the ionic compound formed from magnesium and chlorine has to be given.
Concept Introduction:
Ionic compounds are electrically neutral. This is because there are equal numbers of opposite charges present in the ionic compounds. Empirical formula gives a relative number of atoms of each type of element that is present in the compound to the smallest possible whole-number as subscript.
(b)
Interpretation:
Empirical formula of the ionic compound formed from sodium and oxygen has to be given.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Empirical formula of the ionic compound formed from scandium and selenium has to be given.
Concept Introduction:
Refer part (a).
(d)
Interpretation:
Empirical formula of the ionic compound formed from barium and nitrogen has to be given.
Concept Introduction:
Refer part (a).

(a) copper(I) oxide (b) iron(II) nitride (c) mercury(II) chloride (d) lead(IV) sulfidearrow_forwardObtain an estimate for the number of atoms in the universe. Make the following assumptions: (a) All of the atoms in the universe are hydrogen atoms in stars. (This is not a ridiculous assumption because over threefourths of the atoms in the universe are in fact hydrogen. Gas and dust between the stars represent only about 15% of the visible matter of our galaxy, and planets compose a far smaller fraction.) (b) The sun is a typical star composed of pure hydrogen with a density of 1.4 g/cm^3 and a radius of 7x10^8 m. (c) Each of the roughly 100 billion stars in the Milky Way galaxy contains the same number of atoms as our sun. (d) Each of the 10 billion galaxies in the visible universe contains the same number of atoms as our Milky Way galaxy.arrow_forward
