Why does sodium form a 1+ ion but magnesium forms a 2+ ion

Answers

Answer 1
Answer: because Na has one too many electron to be stable, while Mg has 2. once they loose those electrons, they will be come ion. loosing one electron will give the ion a 1+ charge, and loosing 2 will create a 2+ charge

Which category of minerals is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential?

Answers

The answer is electrolyte.

That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.

Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says  maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .

In what respect does an atom of magnesium differ from a magnesium ion (Mg^{2+})? a. The ion has a more stable electronic arrangement than the atom.
b. The positive charge on the nucleus of the ion is two units greater than the nuclear charge on the atom.
c. The ion has two more protons than the atom.
d. The ion will react more readily with free Cl₂. (E)The ion has two more planetary electrons than the atom. Can anyone explain this one?

Answers

The correct answer is A.  Atoms and ions only differ in the number of electrons each one has and atoms form ions to achieve a more stable electron configuration.  

I hope this helps.  Let me know if anything is unclear.

Which of the following solutions has the highest pH: can you also explain how you can determine if a solutions have a highest pHa)1.00 mol L HNO3 (aq)
b)1.00 mol L KOH (aq)
c)1.00 mol L NaCL (aq)
d)1.00 mol L solution of CaCL2 (aq)

At equal concentrations, which of the following solutions is the most conductive?
a) C6H12O6 (aq)
b) CH3COOH (aq)
c) HClO4 (aq)
d) CH3OH (aq)

Answers

Final answer:

The solution with the highest pH is KOH, because it's a strong base. The most conductive solution would be HClO4, because it's a strong acid and dissociates into ions which are responsible for conducting electricity.

Explanation:

The solution that has the highest pH is b) 1.00 mol L KOH (aq). In the pH scale, lower values (0-6) represent acids, and higher values (8-14) represent bases. As KOH is a strong base, it dissociates completely in water to form K+ and OH- ions, thereby increasing the pH of the solution.

On the other hand, HNO3 is a strong acid and would have a low pH. NaCL and CaCL2 are salts and make neutral solutions, resulting in a pH of around 7.

The most conductive solution at equal concentrations would be c) HClO4(aq). Ionic compounds are good conductors of electricity in a solution since they dissociate into ions. HClO4 is a strong acid and would conduct electricity better than the others. The conductivity is due to the presence of ions which carry the current.

Final answer:

A 1.00 M solution of KOH (aq) would have the highest pH because it is a strong base. A 1.00 M solution of HClO4 (aq) would be the most conductive as it is a strong, fully ionizing acid that produces a high number of ions.

Explanation:

In terms of pH, a solution of 1.00 M KOH (aq) would have the highest pH. The reason is that KOH is a strong base and it completely dissociates in water to form K+ and OH- ions, the latter of which increase the pH of the solution. HNO3, on the other hand, is a strong acid and would result in a low pH. NaCl and CaCl2 are salts and would result in neutral or slightly acidic or basic solutions, depending on the corresponding acidity or basicity of their constituent ions.

Regarding the conductivity, a 1.00 M solution of HClO4 (aq) would be the most conductive. Conductivity relies on the number of ions present in the solution that are capable of carrying current. HClO4 is a strong, fully ionizing acid producing a high number of ions in the solution. The other solutions either are weak acids like CH3COOH, which ionize only partially, or contain compounds like C6H12O6 and CH3OH that don't ionize at all.

B. Small lenses cause more distortion in images than big lenses.

C. Small telescopes gather more radiation from space than big telescopes.

D. Small telescopes produce clearer images of distant objects than big telescopes.

* PLEASE ONLY ANSWER THIS QUESTION IF YOU KNOW YOUR ANSWER IS 100% CORRECT * Thank you! :)

-Also- I have heard there is "no right answer" to this question from others, but I still need to answer it, (preferably correctly!)

Answers

I think the correct answer from the choices listed above is option A. A refracting telescope is made smaller than a reflecting telescope because small lenses cause less distortion in images than big lenses.  They are not subject to chromatic aberration because reflected light does not disperse according to wavelength.
