When are 84 and 63 equal?
Mathematically, never.
What means a half or either of two fairly equal parts?
Mathematically speaking, it means nothing. FAIRLY EQUAL is not half. Half is EXACTLY equal.
What does it mean to have the pH of a solution equal to zero?
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 0, that means that the concentration of H+ is equal to 1 molar, because -log(1) = 0. If you have a 1 M solution of any strong acid, the pH will be equal to zero.
What equals x-15 -8?
-7
What does ''average'' mean mathematically?
"Average" as in arithmetic mean is equal to (a1 + a2 + a3 + ... + an)/n, where ai are elements of a set.
When are 84 and 63 equal?
Mathematically, never.
What does a pH of 7 represent?
A pH equal to 7,00 is the neutral pH.
When angle of incidence is equal to the brewsters angle the reflected and refracted rays are perpendicular to each other Show it mathematically?
when angle of incidence is equal to the brewster's angle, the reflected and refracted rays are perpendicular to each other. show it mathematically.
What means a half or either of two fairly equal parts?
Mathematically speaking, it means nothing. FAIRLY EQUAL is not half. Half is EXACTLY equal.
What property is used to calculate the pH of a solution?
The hydrogen ion concentration in mol/L
What is the formula for weght?
WEIGHT IS EQUAL TO MASS INTO ACCELERATION DUE TO GRAVITY. MATHEMATICALLY: W=mg
Is ten over thirty bigger than 1 over 3?
They're mathematically equal.

What do you call lines of equal pH?
Isoplats.
What is the mathematical definition of pH?
pH is a measure of the concentration of hydrogen ions in a solution. It is defined as the negative logarithm (base 10) of the hydrogen ion concentration in moles per liter. Mathematically, pH = -log[H+].
How can 2 multiplied by 10 equal 2 multiplied by 11?
Mathematically it cannot unless you add 2.
Why is the pH equal to the pKa at the half-equivalence point?
The half-equivalence point is when half of the analyte has been titrated with titrant. At this point, the concentrations of the analyte and its conjugate base are equal, making the pH equal to the pKa because the Henderson-Hasselbalch equation simplifies to pH = pKa.
