The inner core is solid, fourth layer and made out of iron and nickel. It's the one mostly in charge for the other layers. If the inner core stopped spinning, the outer core would lose its magnetic field, and this will be bad because of the sun's radiation wave. Including the other layers.
The outer core is the liquid, third layer. It's in charge of Earth's magnetic field.
The mantle is the second layer of earth, the original temperature can come up about to 1000+ or more, celsius.
Answer:
c. benzoic acid
Explanation:
The given reaction is an example of a Grignard reaction:
When chlorobenzene (C₆H₅Cl) reacts with Mg in ether, an intermediate is formed (C₆H₅MgCl).
Said intermediate then reacts with CO₂ producing a benzoic acid salt (C₆H₅CO₂X), this salt is then neutralized with dilute HCl producing benzoic acid (C₆H₅CO₂H).
Answer:
Keq = 0.217
Explanation:
Let's determine the equilibrium reaction.
In gaseous state, water vapor can be decomposed to hydrogen and oxygen and this is a reversible reaction.
2H₂(g) + O₂(g) ⇄ 2H₂O (g) Keq
Let's make the expression for the equilibrium constant
Products / Reactants
We elevate the concentrations, to the stoichiometry coefficients.
Keq = [H₂O]² / [O₂] . [H₂]²
Keq = 0.250² / 0.8 . 0.6² = 0.217
Answer:
If Thomson's atomic theory was accurate, the positively charged particles would have gone through the foil.
We know that
Speed of light = wavelength X frequency
Energy of light = h X frequency
Where
h = planck's constant = 6.626 x 10–34 j·s
frequency = speed of light / wavelength = 2.998 x 10^8 m/s / 656.3 X 10^-9
frequency = 4.57 X 10^14 / s
Energy = 6.626 x 10–34 j·s X 4.57 X 10^14 / s = 3.028 X 10^-19 Joules
