Answer:
Mass increases since its going from liquid to solid.
Explanation:
Use the ideal gas law:
PV = nRT
so, T = PV / nR
n=0.5
V= 120 dm^3 = 120 L (1 dm^3 = 1 L)
R = 1/12
P = 15,000 Pa = 0.147 atm (1 pa = 9.86 10^{-6} )
Put the values:
T = PV / nR
T = (0.147) (120) / (0.5) (1/12)
T= 426 K
Answer: It changed in identity and properties.
Explanation:
Answer:
Ionic bond
Explanation:
Covalent bonds can only form between non-metals and copper is a metal so it would be an ionic bond.
Answer:
he average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance
