Answer: The main purpose he has for writing this is that the cloaning of humans can be done but it is also very hard to do.
Explanation: But every previous attempt ended in failure or fraud, leading many scientists to wonder if the goal might be impossible to reach.
Answer:
14
Explanation:
A=pi × r²
153.86 = 3.14 × r²
Divide both sides of the equation by 3.14
it becomes:
r²=153.86÷3.14
r²=49
taking the square root for both sides of the equation
r = 7
and
diameter = 2 × radius
diameter = 2 × 7 = 14
Based on the calculations, the solubility of mg(oh)₂ at a pH of 12.70 is equal to 3.4 × 10⁻⁵ M.
<u>Given the following data:</u>
- Ksp of mg(oh)₂ = 1.6 × 10⁻¹³
<h3>What is pH?</h3>
pH is an abbreviation for the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions that are present in a given solution. Thus, the power of hydrogen ions (pH) is generally used to identify or specify the acidity, neutrality, or basicity of any chemical solution.
First of al, we would write the properly balanced chemical equation for this chemical reaction:

Mathematically, the Ksp for the above chemical reaction is given by:
Ksp = [Mg²⁺][OH⁻]²
Ksp = [x][2x]²
1.6 × 10⁻¹³ = 4x³
x = ∛4 × 10⁻¹⁴
x = 3.4 × 10⁻⁵ M.
