Answer:

They all react with acids.  

Explanation:

Thus, they decrease the concentration of stomach acid and provide heartburn relief.

The equations for the reactions are:

  1. Mg(OH)₂ + 2HCl ⟶ MgCl₂ + 2H₂O
  2. Al(OH)₃ + 3HCl ⟶ AlCl₃ + 3H₂O
  3. CaCO₃ +2HCl ⟶ CaCl₂ + H₂O + CO₂

if only 0.264 g of ca(oh)2 dissolves in enough water to give 0.178 l of aqueous solution at a given temperature, what is the ksp
Maurinko [17]

The ksp value for calcium hydroxide at this temperature is 5.20 × 10⁻⁶.

<h3>What is ksp?</h3>

Ksp is an equilibrium constant of a solid substance dissolved in a liquid solution.

Given that, the volume of water is 0.178 l, 0.264 g of Ca(OH)² dissolves in enough water

The solution equilibrium is

Ca(OH)² = Ca + 2OH

The molar solubility is

0.186 / 74.00  / 0.230 = 0.0109 M

The ksp value will be

Ksp = (s) (2S)²

Putting the values in the formula

(0.0109) x (2 x 0.0109)² = 5.20 × 10⁻⁶.

Thus, the ksp value for calcium hydroxide is 5.20 × 10⁻⁶.

Why is an atom regarded as electrically unstable​
meriva

Answer: An atom can be considered unstable in one of two ways. If it picks up or loses an electron, it becomes electrically charged and highly reactive. Such electrically charged atoms are known as ions. Instability can also occur in the nucleus when the number of protons and neutrons is unbalanced.
