The pH of the weak acid is 6.93.
Given,
K= 1.15 *
c=0.102
[H]= K*c= 1.15 * * 0.102= 0.1173 *
p[H]= -log[H]= 6.93
<h3>Weak acid</h3>
A weak acid is one that partially separates into its ions in water or an aqueous solution. A strong acid, on the other hand, completely splits into its ions in water. The conjugate base of a weak acid is also a weak base, and vice versa for the conjugate acid of a weak base. Weak acids have a higher pH than strong acids at the same concentration. Simple arrows pointing left to right are used to represent the reaction of a strong acid ionising in water. On the other hand, a weak acid ionising in water has a double arrow reaction arrow, indicating that both the forward and reverse reactions take place at equilibrium.

That's false. Animals have mitochondria too. It's responsible for cellular respiration, not photosynthesis.
Answer:
4
Explanation:
2HgO
2 * 1 Hg atom = 2 Hg atoms
2 * 1 O atom = 2 O atoms
2+2 = 4 atoms total
Answer:
Demonstrate familiarity with the pH scale ... body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). ... The pH of a solution is a measure of its acidity or alkalinity (base). ... Using a pH meter, you find the pH of an unknown solution to be 8.0.
Explanation:
Answer: A function can be defined as a relation in which one thing is dependent on another for its value.
Explanation: Given R = 8.314J/mol*k
PV = nRT
V = nRT/ P
V = 8.314RT / P (cm^3)
Volume of gas =(( 8.314 * R* T) / P ) cm3
