Answer:
it's subduction
Explanation:
i know this because I just do lol
It is a physical change because it only changed states
<u>Given:</u>
Volume of HCl (VHCl) = 25,0 ml = 0.025 L
Volume of NaOH (VNaOH) = 22.15 ml = 0.02215 L
Molarity of NaOH (MNaOH) = 0.155 M
<u>To determine:</u>
Molarity of HCl
<u>Explanation:</u>
Titration reaction-
HCl + NaOH → NaCl + H2O
Based on the reaction stoichiometry:
1 mole NaOH requires 1 mole HCl
# moles of NaOH = VNaOH * MNaOH = 0.02215*0.155 = 0.003433 moles
# moles of HCl = # moles of NaOH = 0.003433 moles
Molarity of NaOH = 0.003433/0.025 = 0.137 M
Answer:
B. HCl, C. H2SO4, F. HNO3
Explanation:
Acids have hydrogen (H) at the beginning
bases have OH at the end
