typically, over 60% of the mass of a piece of bubble gum is made up of sugar. sugar is dissolved in the mouth and swallowed during chewing. if gum is chewed precisely until it loses its flavor, most if not all of the sugar content of the gum should be gone. how would this affect the mass of the gum? how will the mass of gum be affected by chewing time? how does the chewing time necessary to lose significant mass compare between different brands/types of gum? how large a role does saliva play in the processing of gum in the mouth?

Answers

Answer 1

Answer:

Hello your question is incomplete attached below is the complete question

A) How the mass will be affected by chewing time

The chewing time is an independent variable while the mass of the gum is a dependent variable and would change with increase in chewing time as seen in the regular gum the average mass increase above the average sugar mass before chewing

B) how the chewing time necessary to lose significant mass

The chewing time is neccessary to lose significant mass as seen in the sugar free chewing gum because the more time the gum is chewed the lesser the mass due to the absence/lose of sugar

C) The role saliva play in the processing of gum in the mouth

The saliva mixes up with the sugar contained in the chewing gum to increase its mass as seen when you compare the mean mass value of sugar contained in the regular chewing gum with the mean mass value of the gum after chewing for some time i.e 3.58 < 5.03 , 4.09

Explanation:

we will make two assumptions in order to resolve the given problem

next we have to calculate the mean(average) mass of the Chewing gums for each time interval

Regular gum :

initial mean mass = 5.96

mean mass after 1 minute = 5.03

mean mass after 2 minutes = 4.09

next we calculate the mean mass of sugar in the regular gum  using this relationship :summation of( initial masses * 60/100 )/ 4 = 3.58  comparing it the the mass of the chewing gum at different time intervals i.e 1 minute and 2 minutes

sugar free gum :

initial mean mass = 2.98

mean mass after 1 minute = 2.59

mean mass after 2 minutes = 2.32

A) How the mass will be affected by chewing time

The chewing time is an independent variable while the mass of the gum is a dependent variable and would change with increase in chewing time as seen in the regular gum the average mass increase above the average sugar mass before chewing

B) how the chewing time necessary to lose significant mass

The chewing time is neccessary to lose significant mass as seen in the sugar free chewing gum because the more time the gum is chewed the lesser the mass due to the absence/lose of sugar

C) The role saliva play in the processing of gum in the mouth

The saliva mixes up with the sugar contained in the chewing gum to increase its mass as seen when you compare the mean mass value of sugar contained in the regular chewing gum with the mean mass value of the gum after chewing for some time i.e 3.58 < 5.03 , 4.09

Weak noncovalent interactions:__________ a. do not include ionic interactions b. always involve water. c. can have a large cumulative effect d. combine to form covalent interactions

Answers

Answer:

c. can have a large cumulative effect

Explanation:

Noncovalent interactions between molecules are weaker than covalent interactions. Noncovalent interactions between molecules are of various types which  include van der Waals forces, hydrogen bonding, and electrostatic interactions or ionic bonding.

van der Waals forces  are weak interactions found in all molecules. They include dipole-dipole interactions - formed due to the differences in the electronegativity of atoms - and the London dispersion forces.

Hydrogen Bonds  results when electrons are shared between hydrogen and a strongly electronegative atoms like fluorine, nitrogen, oxygen. The hydrogen acquires a partial positive charge while the electronegative atom acquires a partial negative. This results in attraction between hydrogen and neighboring electronegative molecules.

Ionic bonds result due to the attraction between groups with opposite electrical charges, for example in common salt between sodium and chloride ions.

Even though these noncovalent interactions are weak, cumulatively, they exert strong effect. For example, the high boiling point of water and the crystal structure of ice are due to hydrogen bonding.

A space air is at a temperature of 75 oF, and the relative humidity (RH) is 45%. Using calculations, find: (a) the partial pressures of the dry air and water vapor, (b) the humidity ratio of the moist air, and (c) the specific volume of the moist air. Assume standard sea-level pressure.

Answers

Answer:

A) Partial Pressure of dry air = 13.32 KPa

Partial Pressure of water vapour = 1.332 KPa

B) Humidity ratio; X = 0.0691

C) V_p = 0.8384 m³/Kg

Explanation:

A) We are given;

Temperature = 75°F

Relative Humidity = 45%

Now,to calculate the partial pressure, we will use the relationship;

Relative Humidity = (Partial Pressure/Vapour Pressure) × 100%

Making partial pressure the subject;

Partial Pressure = Relative Humidity × Vapour Pressure/100%

From the first table attached, at temperature of 75°F, the vapor pressure is 29.6 × 10^(-3) bar = 29.6 KPa

Thus;

Partial Pressure of dry air = (45 × 29.6)/100

Partial Pressure of dry air = 13.32 KPa

From online values, vapour pressure of water vapour at 75°F = 2.96 KPa

Thus;

Partial Pressure of water vapour = (45 × 2.96)/100 = 1.332 KPa

B) humidity ratio of moist air is given as;

X = 0.62198 pw / (pa - pw)  

where;

pw = partial pressure of the water vapor in moist air

pa = atmospheric pressure of the moist air

Thus;

X = (0.62198 × 1.332)/(13.32 - 1.332)  

X = 0.0691

C) Formula for moist air specific volume is;

V_p = (1 + (xRw/Ra) × RaT/p

Where;

V_p is specific volume

T is temperature = 75°F = 297.039 K

p is barometric pressure which in this case is standard sea level pressure = 101.325 KPa

pw is partial pressure of the water vapor in moist air = 1.332 KPa

Rw is individual gas constant for water = 0.4614 KJ/Kg.K

Ra is individual gas constant for air = 0.2869 KJ/Kg.K

V_p = (1 + (0.0691 * 0.4614/0.2869)) × 0.286.9 * 297.039/101.325

V_p = 0.8384 m³/Kg

The ionization energy of carbon (C) is:________.
I. smaller than that of fluorine (F)
II. larger than that of fluorine (F)
because: ________.
III. Carbon has less electrons and less electron-electron repulsion making it easier to remove an electron from carbon.
IV. The effective nuclear charge of carbon is smaller, so the valence electrons feel a weaker pull from the nucleus.
V. In carbon, the electron being removed is closer to the nucleus.
VI. In carbon, the electron being removed is farther from the nucleus.

Answers

Explanation:

Ionization energy refers to the minimum amount of energy required to remove the valence electron of an isolated neutral gaseous atom or molecule. Generally, ionization energy increases from left to right across the periodic table.

This means that the ionization energy of Carbon would be smaller than that of Fluorine. The reason for this is due to the smaller effective nuclear charge.

The effective nuclear charge and the atomic size are two factors that ionization energy depends on.

The correct option is;

IV. The effective nuclear charge of carbon is smaller, so the valence electrons feel a weaker pull from the nucleus.

What are the final hydrogen ion concentration and pH of a solution obtained by mixing 400mL of 0.2M NaOH with 150mL of 0.1M H3PO4?

Answers

Answer : The final hydrogen ion concentration is [tex]1.58\times 10^{-13}M[/tex]

Explanation :

The chemical reaction equation will be:

[tex]H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O[/tex]

In this reaction, 1 mole of [tex]H_3PO_4[/tex] reacts with 3 mole NaOH.

So, the number of moles of [tex]H_3PO_4[/tex] present in 150 ml of 0.1 M solution is calculated as follows.

Number of moles = Concentration × Volume

Number of moles = 0.1 M ×0.150 L = 0.015 mol

As it reacts with 3 moles of NaOH.

Number of moles of NaOH = 3 × 0.015 mol = 0.045 mol

So, moles of NaOH in 400 mL of 0.2 M NaOH is as follows.

Number of moles =  0.2 M × 0.4 L = 0.080 mol

Number of moles remained after the reaction = (0.080 - 0.045) mol  = 0.035 mol NaOH in 550 ml (400 ml + 150 ml)

As molarity is the number of moles present in liter of solution. Hence, molarity of NaOH is as follows.

[tex]\text{Molarity}=\frac{\text{Number of moles}}{\text{Volume of solution}}[/tex]

[tex]\text{Molarity}=\frac{0.035mol}{0.550L}=0.0636M[/tex]

Now we have to determine the hydroxide ion concentration.

As, [tex][OH^-][/tex] = 0.0636 M

[tex]pOH=-\log [OH^-][/tex]

[tex]pOH=-\log 0.0636[/tex]

[tex]pOH=1.20[/tex]

Now we have to determine the pH.

As,  pH + pOH = 14

pH = 14 - pOH

pH = 14 - 1.20

pH = 12.8

Now we have to determine the hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

[tex]12.8=-\log [H^+][/tex]

[tex][H^+]=1.58\times 10^{-13}M[/tex]

Therefore, the final hydrogen ion concentration is [tex]1.58\times 10^{-13}M[/tex]

You have a 16 g sample of ethanol with a density of 0.7893 g/mL. What volume of ethanol do you have?

Answers

Answer:

Density is mass/volume d=m/v   so volume = m/d or mass divided by density.

That would be 23 / 0.7893 = 29.1397 or 29.14 mL.  Grams cancels out

Explanation:

The volume of ethanol is 20.27 g/ml.

What is volume?

The area occupied by a three-dimensional object is its volume. It can be determined using density and mass. Liters are used to measure it. The overall weight of a thing is its mass. M designates it.

The mass per unit volume is known as density. The capital letter D and the symbol rho stand for density. You can figure it out by dividing the mass by the volume.

rho = m / V

rho = density

m = mass

V = volume

Given the mass of the sample of ethanol weighs 16 g

The density of 0.7893 g/mL

Putting the values in the equation

Volume = 16 / 0.7893 = 20.27

Thus, the volume of ethanol is 20.27 g/ml.
