The Geiger Counter. Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.
Hope That Helps!!!

The industrial synthesis of ammonia is spontaneous.
to to prove this one calculate the gibbs free energy(delta G)
= delta G = Delta H -T delta s
delta H = -92.2 kj in joules -92.2 x1000 =-92200j
delta s = -199j/k
T= 25+273= 298k
delta G is therefore= -92200-298(-199)=-32898j
since delta G is negative the reaction is therefore spontaneous
Answer:
atomic number
Explanation:
mass is determined by the protons and neutrons
The right answer for the question that is being asked and shown above is that: "(2) the cathode in a voltaic cell and the anode in an electrolytic cell." At the status of electrode does oxidation occur in a voltaic cell and in an electrolytic cell is that the cathode in a voltaic cell and the anode in <span>an electrolytic cell</span>
Answer:
Reactants.
Step-by-step explanation:
The equation for the reverse reaction is
Z + Q ⟶ X + Y; ΔH < 0
A negative ΔH indicates that the energy has been given off.
The products X + Y are at a <em>lower energy level</em> than the reactants Z + Q, and the excess energy has been <em>transferred to the surroundings</em>.
