Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.
Answer: It passes through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km.
Explanation:
Sheild volcanoes contain more water in it. It is a type of volcano that is built entirely of fluid lavas.
Answer:
- <em>There are </em><u><em>4 moles</em></u><em> of chloride ions in 2 moles of calcium chloride.</em>
Explanation:
Start by writing the chemical formula of calcium chloride.
The suffix -ide in chloride means that chlorine is working as the ion Cl⁻, this is with oxidation state -1.
Calcium, being an alkaline earth metal, uses oxidation state +2, Ca²⁺
Then, two atoms of Cl are combined with one atom of calcium, because in this way each Cl atom will accept one electron from a Ca atom, which will donate its two valence electrons.
That is indicated in the chemical formula with subscripts: <u><em>CaCl₂</em></u>, meaning that each formula-unit of calcium chloride has 2 ions of chlorine and 1 ions of calcium, or twice the number of moles of chloride ion.
- 1 mol CaCl₂ : 1 mol Ca⁺ : 2 mol Cl⁻
⇒ 2 mol CaCl₂ : 2 mol Ca⁺ : 4 mol Cl⁻
Hence, there are 4 moles of chloride ions in 2 moles of calcium chloride.
Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.
<h3>Difference between Divergent and convergent boundaries </h3>
Divergent boundaries are the regions where new crust is formed when the plates pull away from each other while on the other hand, Convergent boundaries are the regions where crust is destroyed when one plate dives over another.
So we can conclude that Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.
