Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices. (1) A chemical system reaches equilibrium at the instant when the reactants are consumed and generated at equal rates. (2) One reactant and two or more products is a general characteristic of decomposition reactions. (3) Catalysts increase reaction rate by providing an alternate reaction pathway with a lower activation energy.

the answer to your question is c

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

i wish i could but this one is weird give me abc and i can solve it.

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.
