At the end, 31.70 g of the metal is left over. If O has an atomic mass of 16.00 amu, calculate the atomic mass of M and identify the element. A) 58.7 amu; Ni B) 63.5 amu; Cu C) 65.4 amu; Zn D) 58.9 amu; Co 77. An impure sample of zinc (Zn) is treated with an excess of sulfuric acid (H2SO4) to form zinc sulfate (ZnSO4) and molecular hydrogen (H2).

atomic mass unit (amu). This unit is defined as exactly 1/12 fraction of mass of isotope of carbon 12C. Thus, atomic mass of 12C is 12.000000000 with as many zeros as you want!!! Formula mass. is the sum of . average atomic masses. of all atoms shown in the formula. You can view this as the mass of the molecule expressed in amu’s.

(d) All the elements in H2SO4 are nonmetals. Sulfuric acid consists of molecules. Think about It. The formation of ionic compounds versus the formation of molecular (covalent) compounds can often be predicted by the difference in electronegativity between the bonding elements. Later you will learn the definition of electronegativity (Chapter 8 ...

One is sulfuric acid, one is hydrochloric acid, and the other is nitric acid. Each has a concentration of approximately one molar. Using only aqueous reagents of 0.20 M lead (II) nitrate and 0.50 M calcium nitrate write a short, concise experimental procedure, the results of which will be sufficient to identify each of the unknown acids.
