Question 1
Part A
Describe the sequence of adding ingredients to make the recipe for condensed tomato soup. To mix the ingredients, you have an industrial-sized vat with a capacity of 800 L. You also have the ability to heat what is in the vat and/or stir the vat, both of which require energy and therefore, cost you money. Focus on the fact that the manufacturing process should be time efficient and cost efficient in terms of energy use. Be sure to refer to the solubility charts or graphs that you find for salt and sugar during your research. Finally, presume that the tomato powder has low solubility which is not temperature dependent.
Part B
What changes could be made to optimize the manufacturing process?
Answer:
Part A:
"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

1. Divide by the molar mass
2. Subtract the molar mass
3. Add the molar mass
4. Multiple by the molar mass
Answer: In order to convert from grams to moles of a substance divide by the molar mass.
Explanation:
The number of moles of a substance is the mass of substance in grams divided by its molar mass.
The formula to calculate moles is as follows.
[tex]Moles = \frac{mass}{molar mass}[/tex]
This means that grams are converted to moles when grams is divided by molar mass.
Thus, we can conclude that in order to convert from grams to moles of a substance divide by the molar mass.

Explain the reason that the atomic emission spectrum of hydrogen contains only four lines.
Answer:
Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.

A balloon can hold 10 liters of a gas. If you blow up this balloon with 2 moles of oxygen gas at a pressure of 0.76 atmospheres, what is the temperature of the balloon? Pay attention to the unit of pressure used.
Answer:
The temperature of the balloon is 46.34 K.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
P= 0.76 atmV= 10 Ln= 2 molesR= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= ?Replacing:
0.76 atm* 10 L= 2 moles* 0.082 [tex]\frac{atm*L}{mol*K}[/tex] *T
Solving:
[tex]T=\frac{0.76 atm* 10 L}{2 moles* 0.082\frac{atm*L}{mol*K}}[/tex]
T= 46.34 K
The temperature of the balloon is 46.34 K.

How much heat, in Joules, is needed to raise the temperature of 150 g of manganese by 22°C? (cmanganese = 0.477 J/g°C)
Answer:
1574joules of heat
Explanation:
Q= mc( T2-T1)
=150 * 0.477 *22
=1574 joules
1574.1 Joules heat is needed to raise the temperature of 150 g of manganese by 22°C.
Specific HeatThe quantity or amount of heat per unit mass required to raise the temperature of a body by one degree Celsius is known as specific heat. The unit of specific heat are joules or calories per gram per degree Celsius. Specific heat is an intensive property.
Calculate heat to raise temperature
Relationship between temperature and heat is expressed as:
Q = mcΔT
where,
Q is heat energy in Joules (J)
m is mass (in grams)
c is specific heat in J/g°C
ΔT is change in temperature
Now, put the values in above formula, we get that
Q = 150 × 0.477 × 22
Q = 150 × 10.494
Q = 1574.1 Joules
Thus, we can say that 1574.1 Joules is needed to raise the temperature of 150g of manganese by 22°C.

Explain why for static electricity to occur between two surfaces that are rubbed against each other, one of the materials has to be an insulator
When two surface come in contact and rub each other a frictional force causing them s deformation and this leads to a voltage giving rise to a static charge.
What is static charge?Static charge is developed within a body temporarily with an induced polarization. These charges are not moving and set into a pole in the material.
When two materials rub against each other in which one is a conductor and other to be an insulator, they will attract by the induced polarization. Rubbing causes the free electrons in the condutor to be transferred towards the insulator.
This will cause a deformation that, the random charges in the material get polarized where the electrons in the insulator will repel to the opposite pol and positive charges will align in a pole close to the condutor.
This charge separation causes the positive pole of the insulator gets attracted into the conductor surface. Hence, there forms a static electricity by the passage of electron.

A gas has a volume of 4 liters at 50 oC. What will its volume be (in liters) at 100oC
Answer:
The volume of the gas at 100°C is 4.6189 liters.
Explanation:
For this problem we are going to use Charles' law. Charles' law states that the volume is directly proportional to temperature given that the pressure is constant. In order to use the equation, the unit of temperature should be in Kelvin.
The working equation is:
=
where V1 and T1 are the initial volume and temperature while V2 and T2 are the final conditions.
Let us convert first the temperatures before solving for the final volume.
To convert Celsius to Kelvin just add 273.15 to temperature in Celsius.
50°C + 273.15 = 323.15 K
100°C + 273.15 = 373.15 K
Solving for the final volume:
V₂ =
V₂ =
V₂ = 4.6189 L
Therefore the final volume of the gas at 100°C is 4.6189 L.
