Explanation:
Answer: R
Explanation: is polarized to the right
<span>During a nuclear reaction, an atom must emit an alpha particle, which consists of 2 protons (positively charged) and 2 neutrons (neutrally charged). Thus, the alpha particle has a charge of +2 (there are no electrons, which are negatively charged, to balance out the two protons). When an atom emits an alpha particle, it will lose this particle, thus losing 2 protons and 2 neutrons as well. Since the atom in the equation goes from 84 protons to 82, and 86 neutrons to 84, it lost 2 protons and 2 neutrons, indicating that it emitted an alpha particle.</span>

Explanation:
Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.
Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.
Differences:
Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.
• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.
• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.
• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.
<span>Feb 19, 2014 - The units of k tell you that this is a second order reaction. So, to solve this, you need to use the integrated rate law for a 2nd order reaction: 1/[A] = kt + 1/[A]o 1/[A] = 0.540/Ms (835 s) + 1/0.00640 1/[A] = 607 [A] = 1.65X10^-3 M.</span><span>
