Density of Layers Unknown Layer Density (g/cm3) W 2.8 X 13 Y 4.6 Z 10.5 What is most likely Layer X? Crust Inner core Outer Core Mantle

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

Use the measurements in the table to determine which unidentified metal has the highest density. metal volume mass a 10.5 cm3 122 g b 14.2 cm3 132 g c 16.1 cm3 115 g d 12.7 cm3 126 g

What would happen if no were added to n(g)+o2=2no(g) at equilibrium?
