The tongue depressor will float on water because its density is less than that of water.

<h3>When do substances sink or float in a liquid?</h3>

Substance will either float or sink in a liquid depending on the comparative densities of the substance and the liquid.

A substance will float in a liquid if it is less dense than the liquid.

A substance will sink in a liquid if it is denser than the liquid.

The density of the tongue depressor = 4.54/6.78 = 0.67 g/cm³

The density of water is 1 g/cm³.

Therefore, the tongue depressor will float on water.

In conclusion, the density of substances determines whether thy float or sink in water.

Using de Broglie's equation, λ = h/mv which would have a larger wavelength, a slow-moving proton or a fast-moving golf ball? Exp

tatuchka [14]

Answer: Proton will have larger wavelength

Explanation:

$\lambda =\frac{h}{mv}$ (de-Broglie's equation)

$\lambda =\text{wavelenght of the particle}$

h= Planck constant

m= mass of the particle

v= velocity of the particle

As we can see from the de-Broglie's equation , that wavelength is inversely proportional to the product of mass into velocity of the object.

The wavelength of proton will be higher than that fast moving golf ball because mass of proton $(1.67 \times 10^{-24}g)$ is very small than that of the golf ball (45.93 g). Proton is moving at slow velocity and the golf ball is moving with fast velocity by which value of product of mass into velocity of proton will be lower than the value of product of mass into velocity of the golf ball which will result in larger value of wavelength of the proton.

Does metals replace nonmetals in a compound

AlexFokin [52]

Answer:

A metal only replaces a metal, and a nonmetal only replaces a nonmetal. Only a more reactive element can replace the other element in the compound with which it reacts.

Explain whether nitrogen atoms will form bonds with other atoms.

Nitrogen can make bonds with other atoms.. Typically though it only makes 3 bonds, so it fills its octet.
