Answer:
Explanation:
Using the Arrhenius equation for the give problem:
Taking the natural log (ln) of both sides, we have:
In the given problem, we have two rate constants at two different temperatures. Thus:
(1)
(2)
Subtracting equation (1) from equation (2), we have:
(3)
;
;
Therefore, equation (3) becomes:
-2.507 - (2.531) = Ea*[0.00012 - 0.000099]
Ea = 0.024/0.000021 = 1142.86 J/mol
The activation energy of the reaction in scientific notation is
Answer:
C.) evaporation
Explanation:
When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation.
I hope this helps! :)
Answer:
D
Explanation:
The Phoenicians contributed to ocean exploration by establishing the first trade routes throughout the Mediterranean, even as far north as Great Britain.
Answer:
Acid + Oxide or Hydroxide
Many oxide, hydroxide and carbonate compounds
are insoluble in water, but do react with acid.
Acid + Oxide → Salt + Water
Acid + Hydroxide → Salt + Water
MgO (s) + HNO3 (aq) → Mg(NO3)2 (aq) + H2O (l)
CuOH (s) + HCl (aq) → CuCl (aq) + H2O (l)
Explanation:
lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO2, in which lead is in the +4 state; and trilead tetroxide, Pb3O4. Lead monoxide exists in two modifications, litharge and massicot. Litharge, or alpha lead monoxide, is a red or reddish…
C) convection cells (currents)
Explanation:
The movement of warmer cooler mantle rocks creating a circulation within the mantle is called a convection cell. These are the forces that drives the plate over asthenosphere.
- Convection is form of heat transfer predominant in liquids and gases.
- The mantle is molten and heated from heat within the core and the decay of radioactive bodies.
- Hot bodies are light and tend to be more buoyant. This causes warm mantle to rise to the surface.
- The cold part are denser and heavier, they sink in the mix.
- This creates pockets of circulation pattern within the mantle called convection cells.
