Old thermometers contained very small amounts of mercury. The mercury in the photo has a melting point of -38.8 degrees Celsius. What can you conclude about the melting point of the mercury in old thermometers? * It's melting point can only be determined when the mercury is burned.
It's melting point changes as the temperature of mercury changes.
It's melting point equals -38.8 degrees Celsius because it is mercury.
It's melting point is less than -38.8 degrees Celsius because its volume is smaller.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.

Which subshell is represented by the actinides family?

In medium-sized stars such as the sun, nuclear fusion almost always means the fusing of nuclei to form , but larger stars can produce elements as heavy as
