Which parts of LED bulb needs to stay cool as well as which part must transfer energy away from the diode???
storchak [24]

Answer:

every method of removing heat from LED's should be considered. Conduction, convection, and radiation are the three means of heat transfer. Typically, LED's are encapsulated in a transparent resin, which is a poor thermal conductor. Nearly all heat produced is conducted through the back side of the chip. Heat is generated from the PN junction by electrical energy that was not converted to useful light, and conducted to outside ambiance through a long path, from junction to solder point, solder point to board, and board to the heat sink and then to the atmosphere. A typical LED side view and its thermal model are shown in the figures.

How many moles of h2o will be produced from 2.9 g of HCl reacting with Ca(OH)2?
Igoryamba

Answer:

0.080 mol

Explanation:

 M(HCl) = (1.0 +35.5) g/mol = 36.5 g/mol

2.9g*1mol/36.5 g = 0.0795 mol HCl

                              Ca(OH)2 + 2HCl ---> CaCl2 + 2H2O

from reaction                            2 mol                   2 mol

given                                       0.0795 mol           x mol

x = 0.0795 mol ≈0.080 mol
