Answer:
8 to 8.5 since that is the recommended and people usualy sleep more than that
In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. ... In a longitudinal wave the particles are displaced parallel to the direction the wave travels. An example of longitudinal waves is compressions moving along a slinky.
Hopefully this help you! God bless
Answer: The equilibrium will shift to the left.
Explanation:
If sodium acetate is added to acetic acid, the dissociation of the acetic acid is suppressed. The equilibrium position shifts to the left and the hydrogen ion concentration decreases due to decreased ionization of the acid. This common ion solution becomes less acidic than pure acetic acid.
This is so because of common ion effect. The acetate ion already present from the dissociation of acetic acid is also present in the sodium acetate. The presence of a common ion usually shifts the equilibrium position towards the left.
NaCH3CO2 (s) → Na + (aq) + CH3CO2 −(aq)
CH3CO2H(aq) ⇌ H +(aq) + CH3CO 2− (aq)
