Complete the reactions by writing the products and balance the equations. If no reaction occurs, write “NR” (No Reaction) and explain your answer. 1) Cu3(PO4)2 + Na →

2) MgCl2 + I2 →

3) H2O →

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:

distance, luminosity, brightness, radius, chemical composition, and temperature
