Answer:

Mg⁺² = 0.525 mol/L

Cl⁻ = 1.05 mol/L

Explanation:

The formula for magnesium chloride is MgCl₂, and in a solution the following process takes place:

MgCl₂ → Mg⁺² + 2Cl⁻

By analyzing the stoichiometric coefficients, we can tell that the concentration of Mg⁺² ions is the same as the concentration of MgCl₂, while the Cl⁻ concentration is twice that value.

In other words:

Mg⁺² concentration = MgCl₂ concentration = 0.525 mol/L

Cl⁻concentration = 2 * MgCl₂ concentration = 1.05 mol/L

Why does water evaperate

Juli2301 [7.4K]

Explanation:

water evaporates because when h2o (water) particles heat up, they gain energy causing them to start to vibrate. this moves the oarticles further and further away from eachother and making the substance less dense, and turning it into a gas. meaning it has evaporated

What process removes carbon dioxide from the ocean?

Katen [24]

Answer:

B. decay of dead marine organisms

Explanation:

When the temperature is low, carbon dioxide is captured by the oceans, and when the temperature is high, it is released by the oceans into the atmosphere. At sea, carbon dioxide feeds phytoplankton.

Most of the carbon dioxide consumed by plant plankton (phytoplankton) returns to the atmosphere when this phytoplankton dies or is consumed, but a portion is deposited in the ocean floor sediments when these small particles sink. This process is called a "biological bomb" because carbon dioxide is transported from the atmosphere to the ocean floor.

Predict the two most likely mechanisms for the reaction of 1-iodohexane with potassium tert-butoxide.

Rudiy27

Answer:

C) SN2 and E2

Explanation:

For this question, we have analyzed the substrate and the base/nucleophile. The substrate, in this case, is 1-iodohexane and the base/nucleophile is potassium tert-butoxide.

Substrate

In the 1-iodohexane the iodide "I" is bonded to a primary carbon (carbon 1). Therefore we will have a primary substrate. If we have a primary substrate an Sn1 can not take place. We can not have a primary carbocation due to this instability. So, we can disccard options A) and B).

Base/nucleophile

In the potassium tert-butoxide we have an ionic compound. A positive charge is placed in the potassium atom a negative charge is placed in the oxygen of the ter-butoxide ion. So, we will have a strong base (a molecule with the ability to remove electrons) and a strong nucleophile (a molecule with ability to bond with an electrophile). With all this in mind, we can not have an E1 reaction.

With both analyses, the answer is C).

See figure 1

I hope it helps!
