When magnesium loses it's valence electrons, it has the atomic structure of what element?

1 answer:

4 0

As far as I can tell the best answer for this would be (A) Neon. However, I would argue that this is at the very least a misleading question. Atoms are less identified by their electrons than their protons (which is represented always by its atomic number). Although atoms can gain or lose electrons, the protons would never change (and remain the same element). Personally, I would have written the question as, "When Magnesium loses its valence electrons, its new number of electrons would most closely resemble _____"

GarryVolchara [31]

Answer:

The liver

Explanation:

The liver -

In human beings the location of liver is just in the upper right portion of the abdomen , exactly below the diaphragm .

Liver is present in specifically vertebrates , and is responsible for various metabolism , like producing hormones , decomposition of the red blood cells , regulating the storage of glycogen and the synthesis of proteins .

Liver is the main site for the process of gluconeogenesis , amino acid catabolism .

Liver is the very organ , that has full urea cycle .

Hence , from the given information of the question ,

The correct term is the liver .

Which ion does an acid contain most off

Elena-2011 [213]

Answer:

Hydrogen +

Explanation:

An acid is a chemical which "wants" to donate some protons, or hydrogen + ions. Since a hydrogen atom is just a proton and an electron, the ion lacking an electron is simply a proton. Hope this helps!

What is the molarity of a solution that contains 17 g of nh3 in 0.50 l of solution?

Sauron [17]

Answer:

2.0 M

Explanation:

1) Data:

a) M = ?

b) mass of solue = 17 g

c) solute: NH₃

d) V = 0.5o liter

2) Formulae:

a) number of moles, n = mass in grams / molar mass

b) M = n / V (in liters)

3) Solution

a) Molar mass of NH₃ = 17.03 g/mol

b) n = mass in grams / molar mass = 17 g / 17.03 g/mol = 0.998 mol NH₃

c) M = n / V (in liters) = 0.998 mol / 0.50 liter = 1.996 M

d) Round to the appropiate number of significant figures, 2: 2.0 M.

Answer: 2.0 M

olga2289 [7]

Answer:

Explanation:

Well use the combines gas law to evaluate this question;

P₁V₁/T₁ = P₂V₂/T₂ (Remember that at sea level the pressure is usually 1 atm)

1 * V₁ / 294.25 = 0.72 * V₂ / 277.95 (NB: Temperatures have to be in Kelvin)

V₁ / 294.25 * 277.95 = 0.72 V₂

0.945 V₁ = 0.72 V₂

0.945/0.72 V₁ = V₂

1.312 V₁ = V₂

The volume (V2) at 3000 m altitude will be 1.312 bigger than the initial volume at sea level.
