Gamma rays
Explanation:
Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.
The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.
- Gamma rays also are the most energetic electromagnetic radiation.
- The short wavelength of gamma rays suggests that more waves passes with times.
- It's high frequency shows that a high amount of wave passes through a point at each passing of time.
- These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
- Gamma rays are ionizing radiations which causes ionization of gas molecules.

Answer:
a. 174 mL
Explanation:
Let's consider the following reaction.
2 KI(aq) + Pb(NO₃)₂(aq) → 2 KNO₃(aq) + PbI₂(s)
We have 155.0 mL of a 0.112 M lead(II) nitrate solution. The moles of Pb(NO₃)₂ are:
0.1550 L × 0.112 mol/L = 0.0174 mol
The molar ratio of KI to Pb(NO₃)₂ is 2:1. The moles of KI are:
2 × 0.0174 mol = 0.0348 mol
The volume of a 0.200 M KI solution that contains 0.0348 moles is:
0.0348 mol × (1 L / 0.200 mol) = 0.174 L = 174 mL
Answer:
2.63*10^23
Explanation:
1 mol rhodium = 102.91
44.8g/1 mol * 1 mol/ 102.91mol * 6.022*10^23/1 mol =
2.63*10^23
