What happens on a molecular level when a diatomic molecule is a gas but is then cooled to a solid?

Answer:

As an example of the processes depicted in this figure, consider a sample of water. When gaseous water is cooled sufficiently, the attractions between H2O molecules will be capable of holding them together when they come into contact with each other; the gas condenses, forming liquid H2O. For example, liquid water forms on the outside of a cold glass as the water vapor in the air is cooled by the cold glass.

Explanation:

Hopefully that helps!

Predict the sign for AS for each of the following systems: Water freezing Water evaporating Crystalline urea dissolving Assembly
djyliett [7]

Answer:  1.  Water freezing : \Delta S is -ve.

2. Water evaporating : \Delta S is +ve.

3. Crystalline urea dissolving : \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids: \Delta S is -ve.

5.  Assembly of a protein from individual amino acids: \Delta S is -ve.

Explanation:

Entropy is defined as the measurement of degree of randomness in a system.

It is represented by symbol S and we can only measure a change in entropy which is given by \Delta S.

If there is decrease in randomness , the sign for \Delta S is -ve and If there is increase in randomness , the sign for \Delta S is +ve.

1.  Water freezing: Entropy decreases as we move from liquid state to  to solid state and thus \Delta S is -ve.

2. Water evaporating : Entropy increases as we move from liquid state to  gaseous state and thus \Delta S is +ve.

3. Crystalline urea dissolving : The molecules convert from solid and ordered state to aqueous phase and random state. Thus the entropy increases and thus \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids:  random lipids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

5. Assembly of a protein from individual amino acids: random amino acids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

Calculate the theoretical value for the number of moles of CO2 that should have been produced in each balloon assuming that 1.45
musickatia [10]

Answer:

For 1 antacid tablet (in ballon1) we get .0173 moles of CO2

for 2 tablets (in balloon 2) we get: 2*0,0173=  0.0346 moles of CO2

For 3 tablets (in balloon 3) we get 3* 0.0173 = 0.0519 moles of CO2

Explanation:

The complete question:

Calculate the theoretical value for the number of moles of CO2 that should have been produced in each balloon assuming that 1.45 g of NaHCO3 is present in an antacid tablet. Use stoichiometry (a mole ratio conversion must be present) to find your answers (there should be three: one answer for each balloon).

Balloon 1 had 1 antacid tab

Baloon 2 had 2

Balloon 3 had 3

Step 1: Data given

1.45 g of NaHCO3 is present in an antacid tablet

Molar mass of NaHCO3 = 84.00 g/mol

Step 2: The balanced equation

NaHCO3 + H2O → NaOH + H2O + CO2

Step 3: Calculate moles of NaHCO3

Moles NaHCO3 = mass NaHCO3 / molar mass NaHCO3

1.45g / 84.0 g/mol = .0173 moles

Step 4: Calculate moles CO2

For 1 mol NaHCO3 we need 1 mol H2O to produce 1 mol NaOH 1 mol H2O and 1 mol CO2

For 0.0173 moles NaHCO3 we'll get 0.0173 moles CO2

so for 1 antacid tablet we get .0173 moles of CO2

for 2 tablets we get: 2*0,0173 =  0.0346 moles of CO2

For 3 tablets we get 3* 0.0173 = 0.0519 moles of CO2

Round the following number to four figures: 45.4673
zhenek [66]

This says four figures. The 4 figures you should use are 4546  with a peek at 7 to see what effect it will have on the 4 main figures.

45.467 rounds to 45.47

You round the 4th figure up one. You are not concerned about the decimal places in this question.
