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.

Compare how entropy changes for the following two systems:
postnew [5]

System A undergoes an increase in entropy while system B undergoes a decrease in entropy.

Entropy is the degree of disorderliness of a system. The entropy of a system depends on the number of particles present in the system as well as the state of matter.

Entropy is increased when solid particles dissolve in water because more particles are produced thereby increasing the level of disorderliness in the system.

On the other hand, when vapor is condensed, the degree of disorderliness decreases as gases are converted to liquids.

Calculate the number of moles in 24.18 liters of neon gas at STP.
uranmaximum [27]

The number of moles of Neon gas : 1.079

<h3>Further explanation</h3>

Given

24.18 Liters of Neon gas at STP

Required

The number of moles

Solution

There are 2 conditions that are usually used as a reference in chemical calculations (mainly for determining the volume per mole of a gas or the molar volume), STP and RTP

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So mol for 24.18 L :

= 24.18 : 22.4

= 1.079 moles
