Commercially, liquid vegetable oils are converted to solid fats such as margarine by : Group of answer choices
Answer:
hydrogenation
Explanation:
Liquid vegetable oils are converted to solid fats such as margarine by a process known as hydrogenation.
Commercial production of margarine requires the hydrogenation of liquid oil at a relatively high temperature and pressure and in the presence of a catalyst. During the process, a solid catalyst (usually, nickel) is added to a preheated liquid vegetable oil before the dispersion of the hydrogen gas. The polyunsaturated vegetable oil, thus, becomes saturated or partially saturated in the process. The quality of the final product depends on the degree of hydrogenation or saturation.
The process of hydrogenation turns liquid vegetable oils into solid fats like margarine. therefore, the correct option is option B.
Unsaturated molecules undergo a chemical reaction called hydrogenation in which hydrogen gas is added. Unsaturated fats and oils are frequently transformed into saturated forms, which makes them more stable and solid at room temperature. Margarine, shortenings, and other solid fats are frequently made using this method. In order to increase stability, decrease reactivity, or change the physical and chemical properties of organic compounds, hydrogenation can also be employed to diminish or eliminate double or triple bonds in such molecules.

A sample of gas occupies a volume of 571.5 mL at 0.944 atm and 10 oC. Determine the pressure of this sample at 1.183 L and 32 oC.
Answer:
0.491 atm
Explanation:
Initial volume V1 = 571.5 mL = 0.5715 L
Initial Pressure P1 = 0.944 atm
Initial Temperature T1 = 10 oC + 273 = 283 K (Converting to kelvin units)
Final Temperature T2 = 32 oC + 273 = 305K (Converting to kelvin units)
Final volume V2 = 1.183 L
Final Pressure P2 = ?
These parameters related by the combined gas law;
P1V1 / T1 = P2V2 / T2
Mke P2 subject of formular;
P2 = P1 V1 T2 / V2 T1
P2 = 0.944 * 0.5715 * 305 / 1.183 * 283
P2 = 0.491 atm

Which of the following are kept as a constant in Boyle's law (check all that
apply)
volume
temperature
amount
pressure
none of these
Answer:
temperature
amount
Explanation:
Under the postulate of Boyle's law, both temperature and amount(number of moles) are kept constant.
According to Boyle's law "the volume of a fixed mass of gas varies inversely as the pressure changes if the temperature is constant"
Based on the premise of this law, both temperature and amount of substance is kept constant.
which letters of an air mass represents moisture content
Answer:
Explanation:
One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid. Air masses are classified on weather maps using two or three letters. A lowercase letter describes the amount of moisture in the air mass: m for maritime (moist) and c for continental (dry).
The letter 'c' of an air mass represents moisture content.
What is an air mass?An air mass can be described as a volume of air defined by its humidity and temperature. Air masses are classified depending on latitude and their continental or maritime source regions. Warmer air masses are deemed tropical while Colder air masses are termed polar or arctic.
The maritime and monsoon air masses are moist while Continental and superior air masses are dry. When an air mass will move away from its source region, water bodies and underlying vegetation can quickly modify its character.
The first letter "c" represents its moisture properties in continental air masses (dry) while "m" represents maritime air masses. The letter "T" stands for Tropical, "A" stands for Arctic or Antarctic, "E" stands for Equatorial, "P" stands for Polar, "M" stands for monsoon, and "S" stands for adiabatically drying and warming air.

In our bodies, glucose is broken down into carbon dioxide and water, much like a combustion reaction. How many grams of O2 are needed to fully react with 150g glucose? C6H12O6(s) + 6O2(g) -->6CO2(g) + 6H2O(g)
Answer:
160 g
Explanation:
The chemical equation is:
C₆H₁₂O₆(s) + 6O₂(g) → 6CO₂(g) + 6H₂O(g)
According to the equation, 1 mol of glucose (C₆H₁₂O₆) reacts with 6 moles of O₂. We calculate the masses of the reactants from the molar masses of the chemical elements:
1 mol C₆H₁₂O₆ = (6 x 12 g/mol)+ (12 x 1 g/mol) + (6 x 16 g/mol) = 180 g
6 mol O₂ = 6 x (2 x 16 g/mol) = 6 x 32 g/mol = 192 g
So, 180 g of C₆H₁₂O₆ reacts with 192 g of O₂. The stoichiometric ratio is 192 g O₂/180 g C₆H₁₂O₆. To calculate the grams of O₂ needed to react with 150 g of C₆H₁₂O₆ we can simply multiply the stoichiometric ratio by the grams of C₆H₁₂O₆:
150 g C₆H₁₂O₆ x 192 g O₂/180 g C₆H₁₂O₆ = 160 g O₂
Therefore, 160 grams of O₂ are needed to fully react with 150 g of glucose.

Answer: The energy of the infrared radiation is [tex]19.8\times 10^{-21}J[/tex]
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
[tex]E=\frac{hc}{\lambda}[/tex]
E= energy
[tex]\lambda [/tex] = wavelength of the wave =[tex]1.0\times 10^{-5}m[/tex]

Answer:
carbohydrates, lipids, proteins, and nucleic acids.
Explanation:
Carbohydrates serve several key functions in your body. They provide you with energy for daily tasks and are the primary fuel source for your brain's high energy demands.
The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology.
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

Describe the preparation
of 2.00h of o.108m Bach
from Bad. 28 (244-3 g/mal)
The question is incomplete, the complete question is; Describe the preparation of 2.00 L of 0.108 M BaCl2 from BaCl2.2H2O
Answer:
See explanation
Explanation:
First we must know the molar mass of the compound = 244.3 g/mol
Now we must calculate the number of moles of BaCl2.2H2O in the solution.
number of moles = concentration * volume = 0.108 M * 2.00 L = 0.216 moles
Now the mass of solid that we need to take can be obtained from;
number of moles = mass/molar mass
mass = number of moles * molar mass
mass = 0.216 moles * 244.3 g/mol
Mass = 52.8 g
Hence, we must weigh 52.8 g of BaCl2.2H2O accurately in a balance and dissolve it in 2 L of water to give 0.108 M solution of BaCl2.2H2O.
What nuclide undergoes fission to form molybdenum-103, atomic number 42, tin-131, atomic number 50, and two neutrons?
Element symbol: _______ mass number: _______
Answer:
The correct answer is Pu, 234.
Explanation:
In the given case, let us consider the reactant as X. Now the mass number (balanced) on both the sides will be,
Mass of X = Mass of Molybdenum + Mass of Tin + Mass of neutrons
M = 1 * 103 + 1 * 131 + 2 * 0
M = 234
Now the atomic number (balanced) on both the sides,
Atomic number of X = Atomic number of Molybdenum + Atomic number of Tin + Atomic number of neutrons
A = 1*42 + 1*50 + 2*1
A = 94
The atomic number 94 is for the element Plutonium, whose symbol is Pu. Thus, the reactant is 234-Pu.
