How many boxes in a stack that is 4 wide and 5 high
A stack represents its data using the principle of LIFO on its width and height
There are 20 boxes in the stack
How to calculate the number of boxes?
The given parameters are:
Width = 4
Height = 5
The number of box (n) is calculated using
n = Width * Height
So, we have:
n = 4 * 5
Evaluate the product
n = 20
Hence, there are 20 boxes in the stack

A 20.0-ml sample of a 0.200 mhbr solution is titrated with a 0.200 mnaoh solution. calculate the ph of the solution after the following volumes of base have been added.
The calculated pH of the solutions are given below:
The pH of the solution after 14.0 ml of base is added to it is calculated as 1.45. The pH of the solution after 19.8 ml of base is added to it is calculated as 3.0The pH of the solution after 20.0 ml of base is added to it is calculated as 7. What is pH?This is the level of acidity or alkalinity of an aqueous solution. The pH of a substances tells if its an acid, base or neutral.
HBr and NaOH while in water would dissociate and they would become H+ and OH- respectively.
Mol of HBr = Mol * Vol
= 0.200 * 20mL
= 4 mmol
A. Moles of NaOH added
= 0.2 X 14
= 2.8 mmol
Moles of H+ that did not react
= 4 - 2.8
= 1.2 mmol
1.2/1000 = 0.0012 moles
Total volume = 20 + 14
= 34 mL to litres
= 0.034 L
Molarity of H+ = 0.0012 / 0.034L
= 0.035 M
-log[0.035] = 1.45
The pH of the solution is 1.45
B. NaOH added = 19.8 * 0.2 =
3.96 mmoles
The unreacted solution
= 4.0 - 3.96
= 0.04 mmol
0.04/1000 = 0.00004 moles
Total volume = 20 + 19.8
= 39.8mL
Converted to litres = 0.0398L
Molarity = 0.00004 / 0.0398L
= 0.001
-log(0.001) = 3.0
The ph Is therefore 3.0
C. Moles of NaOH added = 0.2*20mL = 4mmol
All the H+ are going to be consumed here. This would result into a neutral solution pH = 7

Review of peter Sykes please.
Answer:
PETER SYKES is good book which you can definitely refer but you can not entirely rely on this book for your theory as theory in this book containing JEE syllabus is so brief that is hard to understand at once. I personally referred this book rather than SOLOMONS, because I was already in comfort with the organic chemistry and my class notes was enough for me. But our teacher asked us to read this book in general to get better insight on the topics. But if you are not comfortable at the basics itself than this book is not for you definitely, you can use another books like paula yurkaniis bruce, solomons etc. And for questions both MS chouhan and Akshay choudhary is good.

Balanced equationWe'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.

An experiment was carried out to compare electrical resistivity for six different low-permeability concrete bridge deck mixtures. there were 26 measurements on concrete cylinders for each mixture; these were obtained 28 days after casting. the entries in the accompanying anova table are based on information in an article. fill in the remaining entries. (round your answer for f to two decimal places.)
Assuming there were 26 measurements on concrete cylinders for each mixture. Alternative Hypothesis at α=0.01 will be rejected.
HypothesisElectrical resistivity(I)=6
Concrete cylinder measurement(J)=26
First step
Degree of freedom for SSb=I-1=(6-1)=5
Degree of freedom for SSw=I(1-J)=6(1-26)=150
Degree of freedom for SSr=IJ-1=(6×26)-1=155
Second step
Mean square(MSw)=13.929
SSw=MSw×I(J-1)
SSw=13.929×150
SSw=2,089.35
Third step
SSb=SSt-SSw
SSb=5,664.415-2,089.35
SSb=3,575.065
Fourth step
MSb=SSb(I-1)
MSb=3,575.065/(1-6)
MSb=3,575.065/5
