All the fossil fuels...coal, oil, gas...are examples of no return enable energy resources.
q1. all of these
q2 false
q3 can be in liquid, solid or gas forms
q4 idk
q5 They usually remain radioactive for less than 100 years.
q6 idk
q7 TRUE
educated guess and i remember some things from chem. Hope its all good
The answer is c. 104 g because 152-64 equals 88 and 192-88 equals 105
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.
