Answer:
31.36 KJ/mol
Explanation:
mass of the liquid = 74.0 g
heat of vaporization = 21.40 kJ/mol
constant boiling point temperature = 24.09 °C
heat required to vaporize 74.0g = heat of vaporization × mole
mole of Chloromethane = 74.0 g / 50.49 (g/mol) = 1.466 mol
energy required = 1.466 mol × 21.40 KJ/mol = 31.36 KJ/mol
Color implies visible light, so to answer your question: red light has the longest wavelength (~620 - 740 nm). However, there also exists light with even longer wavelengths that is not visible to the human eye, from infrared light to radio waves (with wavelengths that are meters long!)
"NO" is the one among the following choices given in the question that has an incomplete <span>octet in the Lewis structure. The correct option among all the options that are given in the question is the fifth option or the last option or option "E". I hope that this is the answer that has come to your help.</span>
To convert a value from one unit to another, we need a conversion factor to multiply with the value. For this case, we know that for 1hm it is equal to 100 m and that 1 m^3 is equal to 1000 L. We use these:
25 L (1 m^3 / 1000 L ) ( 1 hm / 100 m )^3 = 2.5x10^-8 hm^3
Therefore, the correct answer should be the first option. The statement "<span>fraction cubed: one m over ten to the negative second power m</span>" is not a correct factor.
