Answer: 7
Explanation:
The volume of 0.18 M HClO4 is 100.0 mL.
Calculate the number of moles of 0.18 M HClO4 and 0.27 M LiOH as shown below:
[tex]$$Number of moles $=$ Concentration $\times$ Volume$$\begin{aligned}\text { Number of moles of } \mathrm{HClO}_{4} &=100.0 \mathrm{~mL} \times\left(\frac{1 \mathrm{~L}}{1000 \mathrm{~mL}}\right) \times\left(\frac{0.18 \mathrm{~mol}}{\mathrm{~L}}\right) \\&=0.018 \mathrm{~mol} \\\text { Number of moles of } \mathrm{HClO}_{4} &=66.67 \mathrm{~mL} \times\left(\frac{1 \mathrm{~L}}{1000 \mathrm{~mL}}\right) \times\left(\frac{0.27 \mathrm{~mol}}{\mathrm{~L}}\right) \\&=0.018 \mathrm{~mol}\end{aligned}$$[/tex]
[tex]$$Moles of both acid aand base are equal.\\ $\mathrm{HClO}_{4}$ is a strong acid and $\mathrm{LiOH}$ is a strong base.[/tex]
At the equivalence point, the number of moles of the acid completely reacted with all the moles of the added base. Thus, the solution becomes neutral in nature. The pH of a neutral solution is 7. Therefore, the pH of the solution at the equivalence point is 7.
A find a recurrence relation for the number of bit strings of length n that do not contain three con
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

After telophase 1 of meiosis the chromosomal makeup of each daughter cell is
After telophase I of meiosis, the chromosomal makeup of each daughter cell is: haploid, and the chromosomes are each composed of two chromatids.
What is the chromosomal makeup of a daughter cell after telophase 1?Telophase I: The chromosomes have moved to opposing ends of the cell and are forming two separate chromosomal clusters. Nuclear division occurs at this time, and the parent cell is divided in half, resulting in two daughter cells. Each daughter cell will contain half of the original 46 chromosomes, resulting in a total of 23 chromosomes.
Telophase I is the stage at which the chromosomes have completed their journey to opposing ends of the cell. This will be followed by cytokinesis, which will result in the formation of two daughter cells. Following cytokinesis, the two daughter cells would have genetically distinct chromosomes following meiosis I.
Therefore, After telophase I of meiosis, the chromosomal composition of each daughter cell is: haploid, with two chromatids on each chromosome.

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.
