An incandescent light bulb emits some heat to a room through radiation. approximate the light bulb as a sphere with radius 2.1 cm and having a surface temperature of 97 °c when turned on. a. what is the rate of heat transfer to the room with tsur 24 °c? the emissivity, e, of glass is 0.93. b. if the light bulb is a 25w light bulb, what fraction of the power going to the light bulb is used inefficiently to produce heat?

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall. (use the words "first, second, third, fourth" to fill each blank)experimentinitial conc of a, mol/l initial conc of b, mol/l initial conc of c, mol/l initial rate, mol/l.s1 0.1 0.1 0.2 2 x 10-32 0.2 0.3 0.2 6 x 10-33 0.3 0.1 0.2 2 x 10-34 0.4 0.3 0.4 1.2 x 10-2
