Answer:
The answer to the question is
The wave speed is 53.57 cm/s
Explanation:
The speed of a wave is the distance covered by the wave per unit time.
Wave speed is given by
v = f×λ
where v = The velocity of the wave
f = The wave frequency
λ = The wavelength of the wave
the speed v of the wave can also be expressed interms of the period as
v = λ/T
The freuency of the given wave is f = 5/(0.112 s) = 44.64 Hz and the wavelength is λ = 1.20 cm
Therefore the speed of the wave = 44.64 Hz × 1.20 cm = 53.57 cm/s
Al(NO3)3(aq) + 3NaOH(s) --> Al(OH)3 (s) + 3NaNO3 (aq)
The precipitate here is Al(OH)3 (s), since the solid reactant is the precipitate in the aqueous solution. Usually, it is okay to assume in basic chemistry that the transition metal is going to be part of the compound that is the precipitate, especially in an acidic salt and a strong base reaction that we have here.
The type of chemical bond depends on the substances taking part in it. If the substances are metal and non-metal, then the bond between them is ionic. If two substances are metal, then the bond between them is metallic. If two substances are non-metal, then the bond is covalent.
So basically put this:
Metal + Nonmetal = Ionic
Metal + Metal = Metallic
Nonmetal + Nonmetal = Covalent
