Answer:
The answer is 55.2 that is correct
Explanation:
<span>Weight of CaC2 is 1.53 g
Temparature is 23 celcius T = 23 + 273K = 296K
The pressure of the gas P = 755 torr
Calculating the moles of CaC2 n = 1.53g x 64.0994 mol/g = 0.023869 moles
PV = nRT
V = nRT / P => V = (0.023869 mol) x (62.3636 L Torr / K mol) x (296 K) / 755 torr
Volume of C2H2 = 0.587 L</span>
Infrared is the region in the electromagnetic spectrum to which the maximum intensity of the earth's outgoing radiation.
To explain why it falls on the infrared region of the electromagnetic spectrum, it must be noted that solar radiation powers the climate system of the earth. Some of these are reflected by the Earth and its atmosphere. Now, the earth does not contain the sun's energy from within its vicinity. It gives off infrared radiation through its surface to maintain its internal temperature.
