Given a sample of water at any point on curve AB in Figure 16, what effect would each of the following changes have on that sample?
a. adding energy at constant pressure
b. decreasing the volume at constant temperature
c. removing energy at constant pressure
d. increasing the volume at constant temperature

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

if you're asking what comes out, it's steam.
