The molar solubility of magnesium carbonate is 1.8 × 10–4 mol/l. What is ksp for this compound?
Serhud [2]

Answer:

3.2 × 10⁻⁸

Explanation:

Let's consider the solution of magnesium carbonate.

MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)

We can relate the molar solubility (S) with the solubility product (Ksp) using an ICE chart.

         MgCO₃ ⇄ Mg²⁺(aq) + CO₃²⁻(aq)

I                             0                0

C                          +S              +S

E                            S                S

The Ksp is:

Ksp = [Mg²⁺] × [CO₃²⁻] = S × S = S² = (1.8 × 10⁻⁴)² = 3.2 × 10⁻⁸

Which elements are metalloids? Check all that apply.
Finger [1]
<h3>Answer:</h3>
  • Boron
  • Silicon
  • Tellurium
<h3>Explanation:</h3>
  • Elements in the periodic table are either metals, non-metals or metalloids.
  • Metals are elements that react by losing electron(s) to attain an octet configuration. They occupy groups I, II and III of the periodic table and the transition metals.
  • Non-metals, on the other hand, are elements that react by gaining electron(s) to attain a stable configuration. Examples include halogens and noble gases among others.
  • Metalloids are elements in the periodic table that have the properties of both metals and non-metals.
  • Other examples of metalloids are arsenic, tellurium, germanium and polonium.

What is the hypothesis
Ulleksa [173]
A hypothesis is an educated guess, most likely in an "If... and then..." statement.
So, this paper is asking you to make a hypothesis about this experiment?
So: "If this happened, then this is why." Just add in your own details. :)
