Answer:
<em>Scientists have observed that electromagnetic radiation has a dual "personality." Besides acting like waves, it acts like a stream of particles (called "photons") that have no mass. The photons with the highest energy correspond to the shortest wavelengths.</em>

The two blocks have the same amount of thermal energy.
<h3>Effect of temperature on different mass objects</h3>
Due to platinum metal, the thermal energy is equally distributed in the whole metal so that's equal distribution the thermal energy of both blocks will be the same so we can conclude that the two blocks have the same amount of thermal energy.

Answer:
Electrons will flow from left to right through the wire.
Pb^2+ ions will be reduccd to Pb metal.
The concentration of Sn2+ ions in the left compartment will increase.
Explanation:
Looking at the relative electrode potentials of the two metals
Sn= -0.14
Pb=-0.13
Tin is expected to function as the anode (left hand half cell) and lead as the anode (right hand half cell) tin oxidizes to sn^2+ hence its concentration increases on the left compartment while lead is reduced to ordinary lead metal on the right hand half cell . since oxidation occurs on the left hand side, electrons flow from left to right.
<span>1 mol N2 = 2 mol NH3
325g / 16g/mol = 20.3 mol which ammonia only requires 10.15 mol N2 to produce
10.15 mol x 28.014g/mol
= 284 g
it makes sense that the mass required should be smaller than the mass of the larger product molecules</span>
