For similar light intensity, compact fluorescent bulbs use about 25% of the energy of incandescent bulbs. let's say you replaced a bulb of 40 w with a fluorescent bulb and that your utility charges $0.15/kw-hour. how many dollars would you save in electricity in the 10,000−hour lifetime of the bulb?

What is the value of keq for the reaction expressed in scientific notation?

Sodium nitrite (nano2) reacted with 2−iodooctane to give a mixture of two constitutionally isomeric compounds of molecular formula c8h17no2 in a combined yield of 88%. draw reasonable structures for these two isomers. click the "draw structure" button to launch the drawing utility. place the two compounds in the appropriate boxes below.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
