<span>I would say Antimony (Sb). Similar chemical properties are usually found within the same column of the periodic table. Look at the element above and below arsenic. I chose Sb since it is also a metaloid and Phosphorus is a nonmetal.
hope that helps </span>
Answer:
The "word equation" is Magnesium + Dioxygen → Magnesium Oxide
Explanation: This is also the same as Mg + O₂ → MgO.
Provides equal odds for every member of the population to be choose as a parcipant in the study land
When Be(OH)₂ dissolves it dissociates into the following ions
Be(OH)₂ --> Be²⁺ + 2OH⁻
molar solubility is the number of moles that dissolve in 1 L of solution
If the molar solubility of Be(OH)₂ is 'x', molar solubility of Be²⁺ and OH⁻ ions are x and 2x respectively.
ksp is solubility constant for Be(OH)₂
ksp = [Be²⁺][OH⁻]²
6.92 * 10⁻²² = [x][2x]²
4x³ = 6.92 * 10⁻²²
x³ = 1.73 * 10⁻²²
x = 5.57 * 10⁻⁸ mol/L
molar solubility of Be(OH)₂ is 5.57 * 10⁻⁸ mol/L
Answer:
would be the conjugate base in this reaction according to the Bronsted-Lowry acid-and-base theory.
Explanation:
Among the reactants, the Bronsted-Lowry acid is the species that supplies protons
. The Bronsted-Lowry base would be the species that accept the protons.
On the product side of the equation, the BL-acid donates a proton
to produce the conjugate base. The BL-base accepts a proton
to produce the conjugate acid.
In this case, each
molecule donates a proton to form one
ion. Hence,
Each
molecule would accept a proton to produce an
ion. Hence,
