Answer:
There are 8 valence electrons in an argon atom.
The segment that represents melting is time (minutes) and temperature.
Answer:
The major ionic constituents whose concentrations can be determined from the salinity are known as conservative substances. Their constant relative concentrations are due to the large amounts of these species in the oceans in comparison t
Answer:
15 grams of water will absorb 2,500 Joules in going from 20.0 to 60.0 C.
Explanation:
The heat involved in raising a mass (m) of a substance with a specific heat (c) from one temperature to another (Delta T) is given by:
Heat = mc(Delta T)
2,500 Joules = m*(4.186J/gC)*(60C-20C)
2,500 Joules = m*(4.186J/gC)*(40C)
2,500 Joules = m*(4.186J/gC)*(40C)
m = (2,500J)/(4.186*40J/g)
m = 14.93 grams
