Answer:4.920 X10^-22J
Explanation:
Energy of infrared radiation = hc/λ
where h=plank's constant=6.626X 10^-34js
c= speed of light = 3.0 x 10^8ms⁻¹
wavelength λ= 4.04x 10^-4m
E = 6.626X 10^-34js X 3.0 X 10^8 ms⁻¹/ 4.04 X 10^-4m
=4.920 X10^-22J
Answer:
Constraints are restrictions that need to be placed upon variables
Explanation:
Constraints are restrictions (limitations, boundaries) that need to be placed upon variables used in equations that model real-world situations. It is possible that certain solutions which make an equation true mathematically, may not make any sense in the context of a real-world word problem.
Answer:
2.676e22 atoms of Hydrogen
Explanation:
Knowing the density of water is 1g/ml, 1(g/ml)*0.4ml=0.4 grams of H2O. Knowing that there are 16 grams of H2O in 1 mole of H2O, we can set up a unit conversion of 0.4 Grams H2O * =
2.676e22 atoms of Hydrogen.
