Zinc metal can be obtained from ZnO, by reaction at high temperature with CO, ZnO (s) CO(g) ->Zn(s) CO2 (g) The carbon monoxide (CO) is obtained from reaction; C (s) O2(g) -> CO(g) If 68.0g ZnO and 13.0g O2 were used, how many grams of Zinc would be produced

the answer would be c

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
