Because its a old type of software and probably wont run on your computer
The answer is : Ka=0.000137
HA -> H+ + A-
0.10 x x
0.10-x +x +x
[H+]= 10^-2.44 = 0.00363
x= 0.00363
(0.00363)(0.00363)/(0.10-0.00363) = 0.000137
Ka=0.000137
Answer:
Highlight cells A1:D4, right-click and select Format Cells, click Alignment, and choose the Merge cells option.
Explanation:
We merge cells with the help of following methods.
<u>Method 1 </u>
- Highlight cells A1:D4
- click on the Home tab
- click on the <u>Merge and Center</u> icon in the Alignment group
1st method is not given in options of question.
<u>Method 2</u>
- Highlight cells A1:D4
- right-click and select Format Cells
- click Alignment
- choose the Merge cells option
<em>2nd method is matching with </em><em><u>option D. </u></em><em>So, Option D is the answer.</em>

The role of technology in efforts to explore space could be argued to say that it has helped us to discover many different planets. An IS is a space station that helps us do stuff!!
Answer:
Following are the Python program to this question: t=float(input("Enter time value in seconds: "))#input time in seconds by user
d = t // (24 * 3600) #calculate day and store in d variable t= t % (24 * 3600)#calculate time and store in t variable h = t // 3600#calculate hour and store in h variable t %= 3600#calculate time and store in t variable m=t // 60#calculate minutes and store in m variable t%= 60#calculate time and store in t variable s = t#calculate second and store in s variable print("day:hour:minute:second= %d:%d:%d:%d" % (d,h,m,s))#print calculated value
Output:
Enter time value in seconds: 1239876
day:hour:minute:second= 14:8:24:36
Explanation:
Description of the above can be defined as follows:
- In the above Python program code an input variable "t" is declared, which uses the input method to input value from the user end.
- In the next step, "d, m, and s" is declared that calculates and stores values in its variable and at the last print, the method is used to print its value.
