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.

Properties of the following are:
Alpha particle - positively charged particle (+) that consists of two electrons and two neutrons.
Cathode rays - it is the stream of electrons (negatively charged) found in vacuum.
Protons - are particles that carry positive charge and is present inside the nucleus of an atom.
Electrons - are particles that carry negative charge and is present in the orbits of the atom.
Neutrons - electrically neutral particle (0 charge) present inside the nucleus of an atom. However, it has its own mass.
Answer:
82.9 mL
Explanation:
1. Volume of silver
2. Volume of gold
3. Total volume of silver and gold
V = 4.766 mL + 2.591 mL = 7.36 mL
4 New reading of water level
V = 75.5 mL + 7.36 mL = 82.9 mL
Answer:
AgNO3 + KI → Agl + KNO3. Double-replacement reaction
Explanation:
Based on solubility rules, Silver, Ag produce an insoluble salt in presence of halides (Fluorides F-, Chlorides Cl-, Iodides, I-, and bromides Br-). That means the mixture of AgNO3 (Ag⁺ ions) with KI (I- ions) produce AgI as insoluble salt.
The reaction is:
<h3>AgNO3 + KI → Agl + KNO3</h3><h3 />
And this is a double-replacement reaction where the cations exchange of anion to produce 2 new compounds.
