Answer:
The factors that govern the position of an IR absorption peak includes:
A.)strength of the bond
C.)masses of the atoms involved in the bond
D.)the type of vibration being observed
Explanation:
Infra red spectroscopy covers a range of techniques, mostly based on absorption spectroscopy.
I think the correct answer is proton since protons have a charge of +1 while electrons have a charge of -1. However, since beta particles are used to name a type of nuclear decay and can refer to either a positron or electron depending on the circumstances, your teacher might want you to put beta particle since positrons are basically electrons but that have a positive charge.
I hope this helps. Let me know if anything is unclear.
Answer:
HCl solution - H30+ and Cl ions. pH 3
NaCl - Na+ and Cl-. pH 7
Explanation:
a) HCl solution - the hydrogen ion combines with water molecule to form the hydronium molecule which is responsible for acidity. The chloride ion is also found in solution.
pH = -log [H+] = -log(10^-3) = 3
b) NaCl 10-3 g. The solid dissocates in water forming the Na+ and Cl- ions. None of these ions affect pH
