18 valance electrons, Hope this helps!
Answer:
- The speed of the wave in the rope is 2 m/s
Explanation:
1. <u>Data</u>:
a) ν = 4 Hz
b) λ = 0.5 m
c) s = ?
2. <u>Physical principles and formula</u>:
The propagation of waves in a rope is a classical example of <em>transverse waves</em>: the pulse is inflected in the <em>vertical</em> direction and the wave travels in the <em>horizontal</em> direction, i.e. the pulse or vibration is perpendicular to the motion of the media particles.
The equation that relates <em>speed (s), wavelength (λ), frequency (ν) </em>is:
- wavelength = speed × period
- wavelenfth = speed / frequency
- meter = (meter/second) / second⁻¹
3. <u>Solution</u>:
Answer:
The one with the greatest mass would be the one that has the most things in the nucleus, protons and nutrons
Explanation:
Answer:
HF + LiOH = LiF + H2O.
Explanation:
Hydofluoric acid is a weak acid the solution would be slightly basic due to the following equilibrium (condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.)
