If 355 grams of Lithium Sulfate (FM = 109. 95 grams) is reacted, how much Lithium Phosphate (FM = 115. 79 grams) should be produced in this reaction?
Answers
Approximately 373 grams of Lithium Phosphate should be produced in the reaction.
To determine the amount of Lithium Phosphate (Li3PO4) produced in the reaction, we need to calculate the moles of Lithium Sulfate (Li2SO4) and then use the stoichiometry of the balanced equation to find the moles of Lithium Phosphate.
Given:
Mass of Lithium Sulfate (Li2SO4) = 355 grams
Molar mass of Lithium Sulfate (Li2SO4) = 109.95 grams/mol
Molar mass of Lithium Phosphate (Li3PO4) = 115.79 grams/mol
First, calculate the moles of Lithium Sulfate:
Moles of Li2SO4 = Mass / Molar mass
Moles of Li2SO4 = 355 g / 109.95 g/mol ≈ 3.23 moles
From the balanced chemical equation, we can see that the stoichiometric ratio between Lithium Sulfate and Lithium Phosphate is 1:1. Therefore, the moles of Lithium Phosphate produced will also be 3.23 moles.
Finally, calculate the mass of Lithium Phosphate:
Mass of Li3PO4 = Moles of Li3PO4 × Molar mass of Li3PO4
Mass of Li3PO4 = 3.23 moles × 115.79 g/mol ≈ 373 grams
Therefore, approximately 373 grams of Lithium Phosphate should be produced in the reaction.

Commercial agriculture can often lead to water-quality problems. In one to two sentences, explain how two of those problems occur.(2 points)
Answers
Destroying the wetlands would result in a significant decline in the bay's water quality and ecosystem. Wetlands are natural filters that remove nutrients and chemicals from water as it flows through the area. By destroying the wetlands, the water quality of the bay would decline as pollutants and chemicals would no longer be filtered out. This would have a significant impact on the bay's ecosystem, as many species rely on the bay's water quality to survive.
Two water-quality problems that can arise from commercial agriculture are eutrophication and contamination from pesticides and fertilizers. Eutrophication is the process by which excess nutrients enter a body of water, leading to the growth of algae and other aquatic plants. This can lead to a depletion of oxygen in the water, which can harm aquatic life. Pesticides and fertilizers used in commercial agriculture can also contaminate water sources, leading to health problems for humans and animals that rely on the water.

Topic: Mass Balance. A company sells fishmeal to be used as a protein supplement in certain foods. The process consists of: a. Extraction of fish oil, stage in which a pasta is obtained that has 20% flour and 80% water. b. Drying of pasta in a rotary drum, which produces fishmeal with 40% humidity. How much pasta must be input to the process to produce 1000 kg ?
Answers
To produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta. To determine the amount of pasta required to produce 1000 kg of fishmeal, we need to consider the mass balance of the process. Let's break down the steps involved:
A. Extraction of fish oil:
The pasta obtained from the extraction stage contains 20% flour and 80% water. To calculate the amount of pasta, we need to determine the mass of flour and water in the pasta. Let's assume the total mass of the pasta is P kg.
Mass of flour = 20% of P = 0.2P kg
Mass of water = 80% of P = 0.8P kg
b. Drying of pasta:
During the drying stage, the pasta is dried in a rotary drum, resulting in fishmeal with 40% humidity. This means that the final fishmeal will contain 60% dry matter.
Let's assume the mass of the dried fishmeal is M kg.
Mass of dry matter = 60% of M = 0.6M kg
Since the dry matter in the fishmeal comes from the flour in the pasta, we can equate the mass of dry matter to the mass of flour:
0.6M kg = 0.2P kg
To produce 1000 kg of fishmeal, we want to find the corresponding value of P:
0.6M = 0.2P
P = (0.6M) / 0.2
P = 3M
Therefore, to produce 1000 kg of fishmeal (M = 1000 kg), you would need 3000 kg of pasta.

Answers
Entropy and the inefficiency of energy transfer are part of the Second Law of Thermodynamics.
The first law of thermodynamics states that neither creation nor destruction of energy is possible. The universe becomes more entropic when a spontaneous process occurs, according to the second law of thermodynamics. Thermodynamics' third law: The entropy of a perfect crystal is 0 at absolute zero Kelvin. The overall entropy of a system may only ever increase or stay constant during spontaneous processes, according to the second law of thermodynamics. If the physical process is irreversible, the overall entropy of the system and its surroundings must increase. For a process to be irreversible, the final entropy needs to be higher than the starting entropy: Sf > Si (irreversible process). The overall entropy of a system and its surroundings can remain constant when a system is in thermodynamic equilibrium or undergoing a reversible process. The second law is sometimes known as the Law of Increased Entropy.

what is the proeutectoid phase for an iron– carbon alloy in which the mass fractions of total ferrite and total cementite are 0.86 and 0.14, respectively? (2 pts.)
Answers
The proeutectoid phase in the given iron-carbon alloy with mass fractions of total ferrite and total cementite of 0.86 and 0.14, respectively, is ferrite, with a mass fraction of 55%.
To determine the proeutectoid phase in an iron-carbon alloy with given mass fractions of total ferrite and total cementite, we first need to determine the eutectoid composition of the alloy.
Step 1: Determine the eutectoid composition
The eutectoid composition is the composition of the alloy at which the eutectoid reaction occurs, which is the transformation of austenite to pearlite. For iron-carbon alloys, the eutectoid composition is 0.8% carbon.
Step 2: Compare the alloy composition to the eutectoid composition
The alloy composition given in the question has a higher carbon content than the eutectoid composition, so it is a hypereutectoid alloy.
Step 3: Determine the mass fraction of proeutectoid ferrite
For a hypereutectoid alloy, the proeutectoid phase is ferrite. The mass fraction of proeutectoid ferrite can be calculated using the lever rule:
mass fraction of proeutectoid ferrite = (C - Ce)/(Ceut - Ce)
where C is the carbon content of the alloy, Ce is the eutectoid carbon content, and Ceut is the carbon content of the alloy at which the proeutectoid phase starts to form.
Ceut can be calculated using the lever rule for the proeutectoid cementite:
mass fraction of proeutectoid cementite = (Ceut - C)/(Ceut - Ce)
The mass fractions of total ferrite and total cementite are given in the question as 0.86 and 0.14, respectively. Therefore, we can write:
0.86 = (Ceut - 0.8)/(6.7 - 0.8) --> Ceut = 1.37%
0.14 = (1.37 - C)/(1.37 - 0.8) --> C = 0.96%
Therefore, the proeutectoid phase in this iron-carbon alloy is ferrite, and its mass fraction is:
mass fraction of proeutectoid ferrite = (0.96 - 0.8)/(1.37 - 0.8) = 0.55 or 55%.

What is the term for propane and butane fases that can be liquified?
Answers
The term for the propane and butane phases that can be liquefied is "liquefied petroleum gas" or LPG. LPG is a mixture of propane and butane gases that are compressed and cooled to a point where they transition from their gaseous state to a liquid state.
This process of converting the gases into a liquid form allows for easier storage, transportation, and handling. LPG is commonly used as a fuel for heating, cooking, and powering various appliances. It is widely available in portable cylinders and larger storage tanks. LPG has a higher energy content compared to its gaseous form, making it a convenient and efficient fuel source. The ability of propane and butane to be liquefied and stored as LPG is due to their relatively low boiling points and the pressure at which they are compressed. By controlling the temperature and pressure, the gases can be condensed into a liquid state, allowing for greater convenience and versatility in their use.

Answers
The compound most likely formed with magnesium, Mg, is MgX . The correct option is (A) MgX.
The electronic configuration of the element, X is 2,8,7. Since X is located in group 7 of the periodic table, it has 7 electrons in its valence shell. In order to obtain a stable configuration, the atom can either gain one electron to fill the 3rd energy level completely or lose seven electrons to completely empty the 2nd energy level, which is easier. The resulting ion, X-, would have a stable electronic configuration of 2,8. Hence, the compound most likely formed with magnesium, Mg, is MgX .The correct option is (A) MgX.
Explanation: Magnesium is located in group 2 of the periodic table and has two valence electrons in its outermost shell. It loses these two electrons to form Mg2+ ions with stable electronic configurations of 2,8. On the other hand, element X gains an electron to form X- ions with stable electronic configurations of 2,8.The combination of Mg2+ and X- ions results in the formation of the compound MgX with a neutral charge.
