Overall, Earthquakes<span> radiate seismic energy as both body and surface </span>waves<span>. Traveling through the interior of the earth, body </span>waves <span>arrive before the surface </span>waves<span> emitted by an </span>earthquake<span>. These </span>waves<span> are of a higher frequency than surface </span>waves. The first<span> kind of body </span>wave<span> is the P </span>wave<span> or primary </span>wave<span>.

The most important observation is the conversion of of electrical energy into light energy which performs the function of a lamp.
In addition to this there is a considerable amount of energy loss in form of heat energy. When the electrical lamp is there is production of a significant amount of heat energy. As a result of this the entire energy in form of electrical energy is not converted into light energy
Explanation:
150 grams is .15 liters
1 mole of gas at STP occupies 22.414 liters
.15 liter of hydrogen represents .15/22.414 =
0.0066922 moles of H2
equation is
Zn + 2HCl → ZnCl2 + H2
1 mole of Zn will make 1 mole of H2
0.0066922 moles of Zn will make 0.0066922 moles of H2
To convert this molar quantity of zinc into grams we simply multiply by the atomic mass of zinc, which is
65.38 g/mol;-
Mass of Zn required = 0.0066922 moles * 65.38 g/mol = 0.4375390381 grams
