Molar mass:
HF = 1 + 19 = 20.0 g/mol
Number of moles :
124 / 20.0 => 6.2 moles
Volume = 2.4 L
M = n / V
M = 6.2 / 2.4
M = 2.6 M
Answer A
hope this helps!
Answer:
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.Explanation: hope this helps god bless you
Answer:
The more the temperature the less the effect if magnet
The property makes the materials used in fiber optic cables is:
C. High density
<h3>Fiber optic cables:</h3>
They transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables. Fiber is immune to electrical interference. There is no cross - talk between signals in different cables and no pickup of environmental noise. Information traveling inside the optical fiber is even immune to electromagnetic pulses generated by nuclear devices.
Thus, correct option is C.
