The H2O portion of the formula BaCl2 H2O indicates that this compound is a?
hydrate
How can you determine the melting point of a substance based in its heating curve?
Heating curves (temp vs time) show the transition of a solid to a liquid to a gas. The solid begins to absorb heat, which is represented by a gradual increase in your curve starting from the origin. Eventually, the solid will reach the melting point, at which the temperature will cease to increase until it has fully transitioned to a liquid phase. Therefore, the melting point is the y-value correspondind to the first horizontal portion of the heating curve.
What the free energy will be if the temperature is kept uniform in a system?
When the temperature and pressure is uniform in a system then the free energy is the portion of the system's energy that is able to perform work. It is related to the total enthalpy.
Why does the temperature remain constant in the highlighted portion of the graph even though thermal energy is being added?
the extra energy goes into breaking the bonds in the solid
What portion of air is Nitrogen?
78% portion of air is nitrogen.
What happens to the temperatures in the troposphere as altitude increases?
The temperature decreases

What portion of the ECG indicates ventricular repolarization?
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG

hydrate
What portion of the mantle is hot enough to begin melting rocks into magma?
asthenosphere
What is thought to form by partial melting and in situ crystallization of the melted portion?
migmatite
Which cpt modifier indicates that only the professional portion of the service was performed?

The facts collected during an experiment are called what?
Sample data, if the experiment only captures a portion of the total population and population data, if the experiment captures the entire population.
What is a dependent variable in an experiment?
A dependant variable in an experiment is the portion of the experiment, or "y" variable that is subjected to change as a result of the various forms of the independent variable, or "x" variable.
