What is the solubility of mg(oh)₂ at a ph of 12.70? (ksp mg(oh)₂ is 1.6 × 10⁻¹³)
Based on the calculations, the solubility of mg(oh)₂ at a pH of 12.70 is equal to 3.4 × 10⁻⁵ M.
Given the following data:
Ksp of mg(oh)₂ = 1.6 × 10⁻¹³pH = 12.70What is pH?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:
[tex]Mg(OH)_2(s)\rightleftharpoons Mg^{2+} (aq)+ 2OH^{-}(aq)[/tex]
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.

When 14.0 g of zinc metal reacts with excess hcl, how many litres of h2 gas are produced at stp? zn(s) + 2hcl(aq) → zncl2(aq) + h2(g)
Convert the given mass of Zn to moles:
(14.0 g) (1/65.32 mol/g) ≈ 0.214 mol Zn
According to the balanced reaction, 1 mol H₂ gas is produced for every 1 mol Zn consumed in the reaction, so get the same number of moles of H₂.
Convert this amount of H₂ to a volume at STP:
(0.214 mol H₂) (22.4 L/mol) ≈ 4.80 L H₂

Explanation:
The frequency of a wave increases. if the speed of the wave remains constant, what happens to the distance between successive crests?
Answer:
The distance between successive crests decreases
Explanation:
First some definitions :
Period: The time it takes to make a complete wave or vibration is measured in seconds (s) and is represented by an uppercase T. It is also the time it takes for a particle to perform a complete oscillation.
Frequency: It is the number of cycles produced per second. The frequency is indicated by the lowercase letter f. It is measured in cycles / second or Hertz (Hz). It coincides with the number of oscillations per second that a point makes when it is reached by the waves and shares an inverse relationship with the period (T).
The only way to increase the frequency of a wave at constant speed is to generate an increase in its period.
This means decreasing the distance between successive waves.

In stage 3 identify the structure that made the organism
Answer:
In the first and second stages, the two organisms may show similarities. But when it comes to stage 3 it is possible that the organism can show a different structure. The difference can be seen from for example the front legs, size, eyes, and others.
Explanation:
An organism when viewed in an ecosystem is a community that develops together with the physical environment as a system. Organisms will always adapt to the physical environment, otherwise organisms also affect the physical environment for the purposes of life.
On the other hand, each organism may show similarities, for example certain plant or animal organisms such as the tiger will show similarities. But in a later stage two tigers will show differences even with the same s$x. The difference is, for example, from the shape of the front / back legs, the size, the shape of the eyes, and even the running speed for each tiger.

The recurrence relation for the number of bit strings of length n that do not contain three consecutive zeros is; aₙ = aₙ ₋ ₁ + aₙ ₋ ₂ + aₙ ₋ ₃
How to solve recurrence relations?
Let Sₙ represent a string of length n that does not have 3 consecutive zeros, and let aₙ be the number of such strings.
If we take a string of length n − 1 that does not contain 3 consecutive zeros which is sₙ ₋ ₁.
Now, when we add a₁ to the string, we will have a string sₙ.
If we take a string sₙ ₋ ₂ and add 10 at the end, it will produce a string sₙ.
If we take a string sₙ₋₃ and we add 100 at the end, we will obtain a string sₙ. We see that this string is different from the first two that ended with 1 while this ended with 00. Thus, there are no other possibilities without having 3 consecutive zeros. Thus, we have the recurrence relation as;
aₙ = aₙ ₋ ₁ + aₙ ₋ ₂ + aₙ ₋ ₃
