Be sure to show work and label quantities. Useful constants

Heat of fusion (Hf): 334 J/g Heat of vaporization (Hv): 2260 J/g

Heat capacity (c) of solid water: 2.10 J/g˚C Heat capacity (c) of liquid water: 4.18 J/g˚C

150 kJ are transferred to a 150 g sample of water at 25ºC. What mass of water will evaporate?

chemistry sucks a**

explanation:

14 days is the half-life of phosphorus-32

2b2t

explanation:

2b2t

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
