Answer:
Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
Answer:
True
Explanation:
Pi bonds are formed using p orbitals. Atoms that have p orbitals have 3 of them. In an sp² hybridized atom, only 2 of the 3 p orbitals are being used in the sp² orbitals, leaving one p orbital free for pi bonding. Therefore, only one pi bond can be formed to an sp² hybridized atom.
Answer:
sugars such as dextrose and sucrose increase the surface tension of water. The effect was interpreted as a depletion of the solute molecules from the water-air interface.

For this problem, simply divide the mass of mercury you have by it's density.
100 g / 13.54 g/ml = 7.3855 ml
Since we only have 3 significant digits in 100., you need to round the result to 3 significant digits. So
7.3855 ml = 7.39 ml</span>
