A compound is a chemical combination of two or more elements in definite proportions. For example, two hydrogen molecules + one oxygen molecule= one water molecule. A solution is a physical...
Answer:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
Explanation:
From Google
It's a surface current because it's driven by the winds near the equator.

Answer:
ΔS° = 121kJ , T = 1335K
Explanation:
The reaction:
SO₃(g) + SCl₂=> SOCl₂(l) + SO₂(g)
parameters
SO₃(g) SCl₂(l) SOCl₂(l) SO₂(g)
ΔH°f(kJ/mol) -396 -50.0 -245.6 -296.8
S°(J/mol.k) 256.7 184 - 248.1
ΔG°r = -75.2 kJ
a).
S° of SOCl₂
ΔH°rxn = ΔH°f[Product] - ΔH°f[reactant]
ΔH°rxn = [1 mole * ΔH°f(SOCl2(l)) + 1 mol * ΔH°f(SO2(g))] - [1 mol *ΔH°f(SO3(g)) + 1 mole ΔH°f(SCl2(l))]
ΔH°rxn = [1 mole * -245.6kJ/mol + 1 mol * -296.8kJ/mol] - [1 mol * -396kJ/mol + 1 mole * -50kJ/mol]
ΔH°rxn = -96.4 kJ

Answer:
<h2>0.02 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
We have the final answer as
<h3>0.02 moles</h3>
Hope this helps you
