You had a 69.24 g piece of unknown metal and placed it into hot water at 103°C. You then performed the same experiment as done in class (specific heat of a metal lab) using a Styrofoam cup calorimeter (filled with 75.0 mL of water) and you found that the temperature of the water in the cup rose from 23.0˚C to 27.6˚C, what would the metal’s specific heat be? Identify the metal from the table. (The specific heat of water is 4.184 J/g) I need work to be shown

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: )

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
