Calculate the number of joules released when 10.0 g of steam cools from 120.0 oC to -15.0 oC

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

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

oxygen has 6.

that's it!

if you need further assistance, let me know: )
