You would have to use the molarity of calcium hydroxide to find the moles of calcium hydroxide. Once you have moles, just convert using mole:mole ratio and find the grams of sodium hydroxide.
Answer:
Ice is less dense than water.
There were many, but the most impactful were the Native Americans
Answer:
Titanium
Explanation:
BCC i.e. body-centered cubic is a type of non-primitive unit cell.
In bcc type crystal structure the atoms are arranged in the corners of the unit cell and also on the center of the body of that unit cell.
Among the given options Titanium is the only metal which does not form bcc type crystal structure.
Titanium forms hcp (hexagonal close packing ) type of crystal structure.
The coordination number of hcp is 12 and it is ABAB type lattice.
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
