At 700 k, the reaction 2 so2(g) + o2(g) ⇄ 2 so3(g) has the equilibrium constant kc = 4.3 x 106, and the following concentrations are present: [so2] = 0.10 m; [so3] = 10. m; [o2] = 0.10 m. which of the following is true based on the above? group of answer choices

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.
