14 - 4
= 10 pH
The concentration of hydroxide ions (OH-) in a solution with a pH of 4.0 is 1 x 10^-10 mol/L. This value can be calculated using the relationship between pH and pOH (pOH = 14 - pH), and then using the formula for the concentration of hydroxide ions in water at a given pOH.
Each number on the pH scale represents a 10-fold difference from the number before or after it, so that pH5 is 10x more acidic than pH6 which is 10x more acidic than pH7. Since the difference between 9 and 5 is 4, the acidity would be 4 tens multiplied together: 10 x 10 x 10 x 10 (or 104), BUT.... the question asks for the difference in acidity at pH9 compared to pH5. pH9 is weaker, so we use the inverse. pH9 is only 1/104 as acidic as pH5.
Depends on the concentration. 100% = 3C 93% = -32C 78% = -38C 65% = -64C See:http://www.cise.columbia.edu/clean/msds/sulfuricacid.pdf Remember that the temperatures are NEGATIVE!
The boiling point of maple sap is around 212°F (100°C). This is the point at which the water in the sap evaporates and the sugar concentration increases, leading to the production of maple syrup.
Relative concentration [H+]1 / [H+]2 = 10-(pH1 -pH2) = 10-(7.0-11.0) = 104 == 10,000 times more basic than in pure water (pH=7.0)[Remember that dividing concentrations is substracting both log value of concentration]

The boiling point of a concentrated aqueous solution of sodium chloride is higher than that of pure water. This is due to the presence of the solute, which raises the boiling point of the solution through a process called boiling point elevation. The exact boiling point will depend on the concentration of the sodium chloride in the solution.
A concentrated aqueous solution of sodium chloride (table salt) will start to boil at a higher temperature than pure water, due to the colligative properties of the salt. The boiling point elevation for a 1 molal solution of sodium chloride is around 1.88°C.
It's a trivial linear equation in 'x'.You can find the solution like this:-104 = 8xDivide each side by 8:-13 = x
52%Solution:200 * (x/100%) = 104x/100% = 104 / 200x/100% = 0.52x = 0.52*100%x = 52%
Since the decimal form of 70% is 0.7, 70% of 104 would be 104(0.7). This equals 72.8.
Whenever you minus a negative (number), you add. So it would be 104 - (-13), or 104 + 13, which is 117
It is: 5/9*(104-32) = 40 degrees Celsius
If you have 104 KM it would turn out to be 109.4 M. This is taught in math.
104 sq feet = 104*12*12 square inches which will require 104*12*12/(4*8) = 468 bricks.
I believe he would be 104.
