how many moles are in a pill containing 37.0mg of C12H22FeO14

Catalytic hydrogenation causes the oil to become saturated. So hydrogenated vegetable oil has fewer trans fatty acids and thereby less kinks. The greater the unsaturation (double bonds) the higher is the "kinks" in the fatty acid chains. Hydrogenated vegetable oil have higher melting point causing them to be solids at room temperature such as margarine. In the absence of double bonds (hydrogenated) the fatty acids pack tightly in a crystal lattice. Hydrogenated vegetable oil is likely to clog arteries.

The label on a container of margarine lists "hydrogenated vegetable oil" as the major ingredient. What is the result of adding hydrogens to vegetable oil?

-The hydrogenated vegetable oil has a lower melting point.

-The hydrogenated vegetable oil stays solid at room temperature.

-The hydrogenated vegetable oil has more "kinks" in the fatty acid chains.

-The hydrogenated vegetable oil has fewer trans fatty acids.

-The hydrogenated vegetable oil is less likely to clog arteries.

Oils such as vegetable, olive, sunflower are liquids at room temperature. In the food industry, hydrogen is added to oils in a process called hydrogenation to make them more solid, or 'spreadable'.

Hydrogenated vegetable oils (HVOs) in margarine (Margarine is a spread used for flavoring, baking, and cooking that was first made in France in 1869) used due to benefits like longer shelf-life. But it have bad effects on health because they are main sources of trans fatty acids (TFAs), which are of interest due to their effects on type 2 diabetes mellitus (T2DM).  

Vegetable oils, are oils extracted from seeds, or less often, from other parts of fruits. Vegetable oilsare mixtures of triglycerides.

By adding hydrogens to vegetable oil it changes into a solid form called vanaspati ghee in the presence of nickel called catalyst through the process of hydrogenation.

Solution and explanation;

-The molar mass of Li3PO4 is 115.79 g/mol.

-If lithium is 6.9 g/mol, multiplied by 3 (from Li3PO4), that would be 20.7 g/mol.

-Now we can use this to find the percentage of Li in Li3PO4, 20.7/115.79 = 0.1788 or 17.88%

-This 17.88% can tell us the mass of Li3PO4 using the mass which 0.284. Now lets divide 0.284 by 0.1788 = 1.589 g. This now the mass of Li3PO4.

-Using that, we can now easily find the moles of Li3PO4,

using the molar mass. So (1.589g)(1mol/115.79g)=0.013723 moles of Li3PO4.

-From this, we can now find the volume using molarity (0.362), which is moles per Liter.

= (0.013723 moles)(1L/0.362mol)=0.03791 L

To maximize the volume of the box formed by cutting out squares from a rectangular piece of cardboard, assign a variable 'x' to represent the sides of the squares cut out, and then find the dimensions of the box by subtracting twice 'x' from both the length and the width of the cardboard. The volume of the box is then given by V = x x (12-2x) x (16-2x). Differentiate this equation and solve for x to find the box's dimensions that give maximum volume.

To find the dimensions of the cardboard box with the maximum volume, we first need to assign a variable to the size of a square that is cut out from each corner. Let's call this variable 'x'.

Then, the dimensions of the box are (12-2x) by (16-2x). We get these dimensions by subtracting two times the length of the square cut out from the length and width of the cardboard.

The volume V of the box can be found using the formula V = length x width x height, which in this case becomes V = x x (12-2x)x(16-2x).

To find the maximum volume we would differentiate this cubic equation, set the derivative equal to zero, and solve for x. This is a doable but rather complicated calculus problem and the solutions are not straightforward numbers. However, if this calculation were done the x that results in maximum volume would be found. The dimensions of the box with maximum volume would then be length: 12-2x inches, width: 16-2x inches, and height: x inches.

Answer:

He must be investigating its solubility in water.

Explanation:

Solubility is the maximum amount of a substance that can be dissolved in 100mL or 100g of water at a given temperature.

So if a chemist dissolves some amount of a crystal in 100mL then it shows that is he investigating the solubility.

The rate of dissolution will be measured only if time is also noted.

To understand the reaction one has to do some other test after reaction.

To note the temperature change the chemist must use thermometer.

Answer: its solubility

Explanation:

Relation between pH and concentration of hydrogen ions is as follows.

                  pH = [tex]-log [H^{+}][/tex]

So, it means that an increase in the value of pH will show that there occurs a decrease in concentration of hydrogen ions.

Therefore, the solution becomes basic in nature.

On the other hand, a decrease in the value of pH will show that there occurs an increase in the concentration of hydrogen ions.

Therefore, the solution becomes more acidic in nature.

Hence, if the pH of a solution is decreased from pH 8 to pH 6 it means that the concentration of hydrogen ions has increased in the solution.

If the pH of a solution is decreased from pH 8 to pH 6 it means that the concentration of hydrogen ions in the solution has been increased while the concentration of OH ions have been decreased.

That is;

pH = -Log [H+]

That is;

pOH =-Log[OH-]

Additionally;

pH + pOH = 14

Answer : 49.45 kJ per gram.

Explanation:

Heat of combustion is the amount of heat released on complete combustion of 1 mole of substance.

Given :

Amount of heat released on combustion of butane = 2874 kJ/mol

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]C_4H_{10}[/tex] weighs = 58.12 g

Thus we can say:

58.12 g of [tex]C_4H_{10}[/tex] on combustion releases = 2874 kJ

Thus 1 g of [tex]C_4H_{10}[/tex] on combustion releases =[tex]\frac{2874}{58.12}\times 1=49.45 kJ[/tex]

Thus the heat of combustion of butane, in kJ per gram is 49.45.

Final answer:

The compound C6H12O6 is glucose, consisting of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Its empirical formula is CH₂O, representing a 1:2:1 ratio.

Explanation:

The question is related to the molecular composition of a compound with the formula C6H12O6, which is glucose. In this formula, the numbers indicate the quantity of each type of atom present in a single molecule of glucose. There are 6 carbon atoms (C), 12 hydrogen atoms (H), and 6 oxygen atoms (O). The empirical formula of glucose, which represents the simplest whole-number ratio of the atoms, is CH₂O indicating a 1:2:1 ratio for C:H:O.

To find the molecular and empirical formulas of the compound, we can analyze the ratio of atoms by considering the molecular or molar mass. Using glucose as an example, we understand that (CH₂O)6 equals C6H12O6, demonstrating the relationship between the empirical and molecular formulas. This approach is equally valid when dealing with molar mass (g/mol) rather than molecular mass (amu).

To determine if an unknown solid material is an element or a compound, visual inspection, chemical reaction tests, test tube reactions to see characteristic behaviors, and spectroscopic analysis to identify the types of atoms present can all be utilized. An element will show uniform characteristics and limited reactivity, while a compound will have a fixed ratio of elements and distinct reaction patterns.

To determine whether an unknown solid material is an element or a compound, you can perform a series of tests. An element is a substance that cannot be chemically broken down into simpler substances and is found on the periodic table, while a compound consists of two or more elements that are chemically combined in a fixed ratio.

Identifying an Element or Compound

If the material is an element, it may not react with other substances or only under specific conditions, and spectroscopic analysis will show peaks for only one type of atom. If the material is a compound, it will likely react with other substances and spectroscopic analysis will show the presence of two or more different types of atoms.

To answer more specific questions, like distinguishing between organic and inorganic substances or identifying the substance in a mixture, similar methods such as chromatography, infrared spectroscopy, and other chemical tests can be used.
