Answer:
d) 0.1202 M
Explanation:
Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.
NaOH + HA → NaA + H₂O
The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:
22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol
The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.
The molar concentration of HA is:
2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M
pH = - log[acid] = -log [H+]
pH= -log[10] = 1
Thus, pH is 1
if pH is 7, the solution is neutral and if pH is greater than 7 the solution is basic and if it is less than 7 the solution is acidic.
This solution have pH = 1, thus the solution is acidic.
Cl-35 occurs in greater abundance.
The <em>weighted atomic mass</em> lies <em>closer to 35 u</em> than to 37 u, so the Cl-35 isotope must be more abundant.

Answer:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form"
