For each of the following pairs, predict which substance has the higher entropy per mole at a given temperature: Ar(l) or Ar (g) He (g) at 3 atm pressure or He (g) at 1.5 atm pressure, 1 mol of Ne (g) in 15.0 L or 1 mol of Ne (g) in 1.50 L, CO2(g)CO2(g) or CO2(s).

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

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
