7. Bromine (Bry) is a dark liquid that dissolves differently in polar solvents (like water) and nonpolar solvents (like octane). Which test tube shows bromine in
water (H2O) and bromine in octane (C2H18)? Explain your reasoning.

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Asample of hydrated tin (ii) chloride (sncl2) has a mass of 4.90 g. when it is dehydrated, it has a mass of 4.10 g. which is the correct chemical formula for the hydrate? sncl2•2h2o          sncl2•4h2o          sncl2•6h2o
