Strawberries contain about 15 wt% solids and 85 wt% water. To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass.
a) Draw and label a flowchart of this process.
b) Do the degree-of-freedom analysis and show that the system has zero degrees of freedom (i.e., the number of unknown process variables equals the number of equations relating them). If you have too many unknowns, think about what you might have forgotten to do.
c) Calculate how many pounds of strawberries are needed to make a pound of jam.
d) Making a pound of jam is something you could accomplish in your own kitchen (or maybe even a dorm room). However, a typical manufacturing line for jam might produce 1500 \mathrm{lb}_{\mathrm{m}} / \mathrm{h}. List technical and economic factors you would have to take into account as you scaled up this process from your kitchen to a commercial operation.

Answer:

From solutions that evaporate

From hot water solutions when the solution cools

Explanation:

The substances that can form minerals can be dissolved in the water to form a solution. Solution can be described as as a mixture in which a solute is dissolved in a solvent. When a particular dissolved solute evaporates from the solution, crystals of minerals might form. The mineral halite was formed when seas evaporated over a period of time.

The minerals can also be formed when a hot water solution gets cooled.

Solubility can be defined as a terminology that describes how readily a chemical substance or compound can be dissolved in a solvent to form a solution.

In Chemistry, a chemical substance or compound is said to be soluble if it dissolves completely in a solvent such as water.

Based on Table F, the chemical compound which is least soluble in water is [tex]AlPO_4[/tex] because phosphates are generally insoluble.

The given question is incomplete. The complete question is:

When 136 g of glycine are dissolved in 950 g of a certain mystery liquid X, the freezing point of the solution is 8.2C lower than the freezing point of pure X. On the other hand, when 136 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 20.0C lower than the freezing point of pure X. Calculate the van't Hoff factor for sodium chloride in X.

Answer: The vant hoff factor for sodium chloride in X is 1.9

Explanation:

Depression in freezing point is given by:

[tex]\Delta T_f=i\times K_f\times m[/tex]

[tex]\Delta T_f=T_f^0-T_f=8.2^0C[/tex] = Depression in freezing point

[tex]K_f[/tex] = freezing point constant

i = vant hoff factor = 1 ( for non electrolyte)

m= molality =[tex]\frac{136g\times 1000}{950g\times 75.07g/mol}=1.9[/tex]

[tex]8.2^0C=1\times K_f\times 1.9[/tex]

[tex]K_f=4.32^0C/m[/tex]

Now Depression in freezing point for sodium chloride is given by:

[tex]\Delta T_f=i\times K_f\times m[/tex]

[tex]\Delta T_f=20.0^0C[/tex] = Depression in freezing point

[tex]K_f[/tex] = freezing point constant  

m= molality = [tex]\frac{136g\times 1000}{950g\times 58.5g/mol}=2.45[/tex]

[tex]20.0^0C=i\times 4.32^0C\times 2.45[/tex]

[tex]i=1.9[/tex]

Thus vant hoff factor for sodium chloride in X is 1.9

Answer:

The volume is decreasing at a rate of 30 cm³/min.

Explanation:

From the question given above, pressure (P) and volume (V) are related by the following equation

PV = C

C => constant

If we make P the subject of the above, we shall have:

P = C/V

From the equation above (i.e P = C/V),

We can say that P is inversely proportional to V. This implies that as P is increasing, V will be decreasing and also, as P is decreasing, V will be increasing.

Considering the question given above, the pressure (P) is increasing at a rate of 30 kPa/min. Therefore, the volume will be decreasing at a rate of 30 cm³/min.

Answer:

Three ways that I would make most of this situation are going near an area to avoid the things drifting into space. I would seek shelter in a basement. I would also stay indoors.

Earth's atmosphere and its oceans, rivers, and lakes would be one of the first things to drift away into space, we would need to avoid those obstacles by seeking shelter. The first problem is that Earth is rotating at high speed, rather like the way a weight on a string rotates if you spin it around your head. Anyone unfortunate enough to be outside at the time would quickly be lost. People inside buildings would be safer because most buildings are so firmly rooted to the ground that they would stay put even without gravity – at least for a while.

Gravity is the universal force that attracts matter. If there is less gravity, then the objects on the Earth will become weightless.

Gravity or the gravitational force is the fundamental force present in the universe that keeps the matter attracted to each other. It plays a major role in the rotation of the earth around the sun and keeps the atmosphere of the planet balanced.

In case of no gravity, the objects will become weightless and will start to float, and Earth will stop rotating and will collide with the sun. Also, the moon will collide with the earth and the objects will perish in the universe.

Answer:

[tex]m_{CO_2}=1.27gCO_2[/tex]

Explanation:

Hello!

In this case, since the combustion of butane is shown below:

[tex]C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O[/tex]

We can evidence the 1:4 and 13/2:4 mole ratio of butane to carbon dioxide and oxygen to carbon dioxide respectively. Thus, in order to compute the maximum amount of carbon dioxide produced in this reaction, we set up the following stoichiometric work:

[tex]m_{CO_2}^{by\ C_4H_{10}}=4.00gC_4H_{10}*\frac{1molC_4H_{10}}{58.12gC_4H_{10}}*\frac{4molCO_2}{1molC_4H_{10}}*\frac{44.01gCO_2}{1molCO_2}=12.11gCO_2\\\\ m_{CO_2}^{by\ O_2}=1.50gO_2*\frac{1molO_2}{32gO_2}*\frac{4molCO_2}{13/2molO_2}*\frac{44.01gCO_2}{1molCO_2}=1.27gCO_2[/tex]

Thus, since oxygen yields the fewest amount of carbon dioxide, we infer the former is the limiting reactant and therefore the maximum amount of carbon dioxide product is 1.27 g.
