Explanation:
a) Both A and R are true and R is the correct
explanation of A.
Answer:
Explanation:
A. Ethanoic acid-acetic acid being weak acid dissocated weekly and turns solution to weakly acidic, ph will be between 4-7,
B. Hydrochloric acid - the solution would be acidic- with lots of H+ ions, Ph will be between 1-4,
C. Sodium chloride - solution prodcued netural Na+ and Cl- hence wont affect ph of solution will be equalt to 7.
D. Sodium hydrogen carbonate-NaHCO3 is weak base and the PH will be above 7,
hope these helps you to find your answer
Convert metres to feet:
343m*3.28f = 1,125.04ft/s
There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.
1,125.04ft*3600s = 4,050,144 ft/h
Now, since you asked for miles, convert to miles (5280 ft in a mile):
4,050,144ft/5,280m = 767.072mph
That is your answer! Hope I helped. :)
