Answer:
quartz and olivine
Explanation:
According to my research on studies made by different geologists on Bowen's reaction series, it is known that crystal settling should result in the magma being separated in lower layers rich in the early-formed quartz and olivine minerals.

Answer:
Hi
Isopropyl alcohol is a colorless, flammable liquid with an intense smell and miscible with water. It is an isomer of 1-propanol. It is obtained by means of a hydration reaction with propylene. It is also produced by hydrogenation of acetone. There are two main ways for the process of hydrating propylene: indirect hydration by sulfuric acid and direct hydration. The type of bond that presents hydrogen bonds and dipole-dipole forces.
Explanation:
Explanation:
Before proceeding to answering the questions, let us go over some definitions.
pH scale: The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.
pH stands for Potential of Hydrogen. It refers to the hydrogen ion concentration in a solution.
The keywords being; Hydrogen Ion concentration.
A Bronsted-Lowry acid is a chemical species that donates one or more hydrogen ions in a reaction.
A Lewis acid is any substance that can accept a pair of nonbonding electrons. It is an electron pair acceptor.
An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons.
Based on the definitions of given above, it is obseved that both Bronsted lowry and arrhenius acids deals with hydrogen ions. Hence both of this acids can be measured using the pH scale. The lewis acid on the other hand do not necessarily contain hydrogen ions, hence the pH scale cannot be utilized for it.
Examples includes;
Arrhenius acid; Nitric Acid – HNO3 etc
Lewis acid; boron trifluoride (BF3) and aluminum fluoride (AlF3) etc
Bronsted lowry acid; HCl etc
NH₃ would. This is because of the fact that ammonia is a molecular gas while the other options are ionic crystals. Crystals increase in solubility when the temperature increases while gases increase in solubility while temperatures deceases.
I hope this helps. Let me know in the comments if anything is unclear or if you want me to explain anything is more detail.
