Geological settings whereby there is melting of rock as well as formation of sediments can be attributed to Plate tectonics .

Plate tectonics can be regarded as  theory which explained the Earth's outer shell and how its been divided into solid rocks as well as slabs and its often referred to as Plate.

Therefore, plate tectonic  gives explanation about Earth's outer shell.

A spontaneous reaction is one in which the change in free energy is negative and the standard cell potential is positive.

For a redox reaction to be spontaneous, the electrode potential of the cell must be positive and this depends on the relative electrode potentials of the species involved in the reaction. A metal can not displace a metal above it in the electrochemical series from solution.

Answer:  Count only the electrons in the highest shell s and p orbitals when determining valence.

Explanation:  I'm glad you asked this question.  It is often not well explained.   The term valence electrons is assigned to only the electrons in an element's highest energy level.  These reside only in the s and p orbitals, and not the d or f, as I'll explain later.  The s orbital can hold 2 electrons and the p can hold 6.  Potassium, K, has an s orbital in its highest energy shell, 4.  It contains only 1 electron, so it has a valency of 1.  

Calcium, Ca, has 2 in its highest energy level: 4s^2, so it has a valency of 2.   Moving to the right, the element scandium, Sc, add another electron, but it goes into the 3d orbital.  3d is in the 3rd energy shell, so it is not counted as a valence electron.  Only after we move further right, to gallium, Ga, do we start adding electrons to the 4th energy level again - the 4p orbitals can accept up to 6 electrons.  Ga has 3 valence electrons - 2 in the 4s and 1 in the 4p.  Oxygen has 2 in the 2s and 4 in the 4p orbitals, for a total of 6.  It is close to having a comple outer shell (2 in the 2s and 6 in the 2p).  Just 2 more electrons would fill both the 2s and 2p orbitals for a total of 8 valence electrons, a stable configuration (the same configuration as thje stable gas Neon).

Answer:

The amount of sodium chloride.

Explanation:

This is because an independent/manipulated control is something that is changed or controlled by the experimenter. Jax has control over the change of sodium, therefore the answer is the amount of sodium chloride.

Explanation:

Substances that have greater affinity for the solvent travel faster while the substance that have greater affinity for the paper travel more slowly.

Chromatography involves a mobile phase and a stationary phase. The mobile phase is the solvent that carries the mixture. while the stationary phase is the medium that performs the actual separation

The speed with which components of the  ink moves up the paper depends on its affinity for the paper or the water.

The different colors in the ink separate because some colors had a greater affinity for the paper or water. The colors that had a greater affinity for the water moved faster, and those with a greater affinity for the paper moved slowly up the paper.

Answer:

3.6 atm

Explanation:

10. A balloon is blown up to a volume of 18 L at a pressure of 1.0 atm and

298 K. What would the pressure inside the balloon be when its volume

becomes 4.0 L and its temperature is 239 K?*

PV/T = P'V'/T'

(18 X 1)/298 =(P' X 4)/239

so

P' = (18 X 239)/(298 X 4)= 3.6 atm

P'=(18 X 239)/(298 x 4)  =

As a chemist, the classification of substances as elements, mixtures, or compounds is of more importance than the state of the substances.

The state of substances is mostly obvious to the eyes, even to those that are not chemists. In other words, the state of matter of substances is just a physical property that can be easily discerned.

Whether a substance is an element, mixture, or compound, however, is something that may not be discerned physically without carrying out some chemical analyses.

Thus, a chemist would be more interested in the classification of substances as elements, compounds, or mixtures.
