Fructose is a form of carbohydrate, while a triglyceride is a lipid.
A triglyceride is a polymer, while fructose is a monomer.
Answer:
Fatty Acids
A lipid is an organic compound such as fat or oil. Organisms use lipids to store energy, but lipids have other important roles as well. Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH3(CH2)nCOOH" role="presentation" style="display: inline-table; font-style: normal; font-weight: normal; line-height: normal; font-size: 17.6px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">CH3(CH2)nCOOHCH3(CH2)nCOOH, where n" role="presentation" style="display: inline-table; font-style: normal; font-weight: normal; line-height: normal; font-size: 17.6px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">nn usually ranges from 2 to 28 and is always an even number. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids.
Saturated Fatty Acids
In saturated fatty acids, carbon atoms are bonded to as many hydrogen atoms as possible. This causes the molecules to form straight chains, as shown in the figure below. The straight chains can be packed together very tightly, allowing them to store energy in a compact form. This explains why saturated fatty acids are solids at room temperature. Animals use saturated fatty acids to store energy.

Unsaturated Fatty Acids
In unsaturated fatty acids, some carbon atoms are not bonded to as many hydrogen atoms as possible due to the presence of one or more double bonds in the carbon chain. Instead, they are bonded to other groups of atoms. Wherever carbon binds with these other groups of atoms, it causes chains to bend (see figure above). The bent chains cannot be packed together very tightly, so unsaturated fatty acids are liquids at room temperature. Plants use unsaturated fatty acids to store energy.

Lipids and Diet
Unsaturated fat is generally considered to be healthier because it contains fewer calories than an equivalent amount of saturated fat. Additionally, high consumption of saturated fats is linked to an increased risk of cardiovascular disease. Some examples of foods with high concentrations of saturated fats include butter, cheese, lard, and some fatty meats. Foods with higher concentrations of unsaturated fats include nuts, avocado, and vegetable oils such as canola oil and olive oil.
Fructose is a simple carbohydrate sugar, while triglycerides are the lipids or the fats of the body. Thus, option C is accurate.
What are triglycerides and fructose?Triglycerides are lipids of the body that are formed of fatty acids and glycerols. It makes the body fat of the animals and of the plants. They are stored in cells for future use and provide energy when needed.
Fructose is a monomer that is the simplest carbohydrate sugar and is generally found in sugarcane, honey, watermelon, grapes, apples, etc.

how would you expect the solubility of barium sulfate in pure water to compare to its solubility in 0.10 m nacl
Answer:
barium sulfate is insoluble (unable to dissolve) in water.
the general equation for the reaction between solid barium sulfate and nacl solution is this:
BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)
to sum this up, to compare the solubility,
1. barium sulfate cant dissolve in pure water.
2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.
good luck!
The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.
What is solubility?
Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.
Barium sulphate is insoluble in water beacuse it has higher lattice energy as well as higher size of cations & anions as compare to water, due to which water is not able to attract these ions towards itself affectively.Barium sulphate is soluble in the NaCl solution as this solution having ions which have more power to attract the ions of barium sulphate and show dissolution. Chemical reaction for this will be represented as:BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)
Hence, barium sulphate is insoluble in water.

Answer:
Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.
The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.
Answer:
Q1
Copper
Explanation:
Copper is a good conductor of electricity, its resistance is high, and its chemical activity is weak
Q2
The thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows.
Would you expect the shielding effect to be greater in bromine than in chlorine?
A. Yes, because there are more filled orbitals in bromine.
B. Yes, because bromine has a higher atomic number.
C. No, because they are both in the same family.
D. No, because chlorine has a higher electronegativity than bromine.
The shielding effect of bromine is greater than chlorine because there are more filled orbitals than in chlorine.
Shielding EffectThis is the process where by electrons are protected by the pull attraction of the nucleus with the use of electron shells. The shielding effect increases down the group of the periodic table and increases across the period. This is because when you move down the group, there's an increase in the number of shell by 1 and it helps to reduce the effect of nuclear attraction on the electrons. However when you move across the period, there's an increase in the numbers of electron with the same shielding electrons from group 1(a) across the period to group 7(a).

The chemical equation below shows the decomposition of ammonium nitrate (NH4NO3). NH4NO3 Right arrow. N2O 2H2O A chemist who is performing this reaction starts with 160. 1 g of NH4NO3. The molar mass of NH4NO3 is 80. 03 g/mol; the molar mass of water (H2O) is 18. 01 g/mol. What mass, in grams, of H2O is produced? 9. 01 18. 01 36. 03 72. 6.
The mass of water, H₂O produced from the reaction is 72.06 g
We'll begin by calculating the mass of NH₄NO₃ that reacted and the mass of H₂O produced from the balanced equation.
NH₄NO₃ —> N₂O + 2H₂O
Molar mass of NH₄NO₃ = 80.03 g/mol
Mass of NH₄NO₃ from the balanced equation = 1 × 80.03 = 80.03 g
Molar mass of H₂O = 18.01 g/mol
Mass of H₂O from the balanced equation = 2 × 18.01 = 36.02 g
From the balanced equation above,
80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O
Finally, we shall determine the mass of H₂O produced by the reaction of 160.1 g of NH₄NO₃.
From the balanced equation above,
80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O.
Therefore,
160.1 g of NH₄NO₃ will react to produce = (160.1 × 36.02) / 80.03 = 72.06 g of H₂O.
Thus, the mass of water, H₂O produced from the reaction is 72.06 g

The type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.
What are bonds?Bonds are defined as any of the interactions that lead to atoms joining together to form molecules, ions, crystals, and other stable species that make up the familiar materials found in everyday life. The ability to build molecules is made possible by a chemical bond, which is a strong attraction between atoms, ions, or molecules. Chemical bonds that hold molecules together also form temporary connections vital for life.
Covalent bond are defined as a type of chemical link where atoms share electrons to create electron pairs. Low melting and boiling temperatures, low vaporization heat, low water solubility, and poor conductivity are four characteristics of covalent compounds.
