Fatty acids are part of the structure of many lipids except for sterols.

What are lipids?

Lipids are macromolecules made up of hydrocarbon chains or rings, which means that they contain a lot of energy. Lipids are organic molecules that contain carbon, hydrogen, and oxygen in a proportion that varies depending on the specific molecule. They are non-polar and insoluble in water, which means that they do not dissolve in water.

Lipids are categorized into three different classes: Fats and oils (triglycerides), phospholipids, and steroids. They are essential to many cellular functions, including energy storage, insulation, and membrane formation.

Examples of lipids include butter, oil, and cholesterol.

Silk produced by different species of spiders can vary in strength, elasticity, and other properties. Some species of spiders produce silk that is very strong and durable, while others produce silk that is more elastic and stretchy.

The variation in silk from spider to spider is due to differences in the genes that encode for the production of silk. Different species of spiders have evolved to produce silk with different properties in order to suit their specific needs, such as building webs to capture prey or constructing cocoons to protect their eggs. Environmental factors, such as the availability of nutrients and the presence of predators, can also influence the properties of silk produced by a particular spider.

Gossamer silk is a type of silk produced by some species of spiders, such as the orb-weaving spiders, that is characterized by its thin, delicate, and transparent nature.

Sticky spider silk is a type of silk produced by some species of spiders that is coated with a sticky substance called glue. The sticky glue helps to capture insects that become stuck in the web, making it easier for the spider to wrap and eat its prey.

The diving bell spider (Argyroneta aquatica) is unique in that it is the only species of spider that can live and reproduce entirely underwater. It does this by constructing a "diving bell" out of silk and air, which it uses to breathe and to protect its eggs and young.

Therefore, The Darwin's bark spider (Caerostris darwini) is known for producing the strongest and most elastic silk of any spider species. It uses this silk to construct large, complex webs that can span across rivers and other bodies of water.

Answer:

Charge of an ionic element = Number of protons (p) - Number of electrons (e)

Explanation:

Atoms of elements are made up of three subatomic particles viz: neutron, proton and electron. The proton is the subatomic particle that carries the positive charge (+) while the electron is the subatomic particle that carries the negative charge (-).

The atom of any element is NEUTRAL when the number of protons in its nucleus is equal to the number of electrons surrounding its nucleus. However, an ion (charged atom) arises when there is a difference in the number of protons and electrons in an atom.

The equation to determine the charge an ion will carry is: NUMBER OF PROTONS (p) - NUMBER OF ELECTRONS (e).

This equation shows that an ion will be:

- positively charged if the number of protons is > number of electrons.

- negatively charged if the number of protons is < number of electrons.

At constant pressure if ΔH is equal to zero, then q also will be zero. And work done W and internal energy change ΔE  = - PΔ V.

The enthalpy of a system can be defines as the sum of the internal energy of the system and its addition pressure -volume energy of occupying space.

H =  E + PV

Then change in enthalpy ΔH = ΔE + PΔ V

Now, if ΔH = 0,

ΔE = - PΔ V.

According to first law of thermodynamics,

ΔE = q + w

then q + w = - PΔ V

where w = - PΔ V

therefore, q = 0.

From this, the enthalpy change is equal to the heat added at constant pressure.

ΔH = q at constant pressure.

hence q = 0.

ΔE = w =- PΔ V.

Answer:

a rate at which something moves fast

Answer:

3.38 moles.

Explanation:

The following data were obtained from the question:

Mass of copper (Cu) = 215 g

Number of mole of copper (Cu) =...?

The number of mole of copper (Cu) in 215 g can be obtained as follow:

Mass of copper (Cu) = 215 g

Molar mass of copper (Cu) = 63.55 g/mol

Number of mole of copper (Cu) =...?

Mole = mass /Molar mass

Mole of Cu = 215/63.55

Mole of Cu = 3.38 moles

Therefore, 3.38 moles of copper (Cu) is present in the sample.

Answer:

There is only one possible value for the quantity "c"

Explanation:

There is only one possible value for the quantity "c". This is because the a,b,c and d represent number of moles in he balanced equation. And since the number of moles of a particular substance (atom or compound) in a balanced equation must be distinct, it (the substance) can only have one value. For example, consider the equation below

2C₂H₂ + 5O₂ ⇒ 4CO₂ + 2H₂O

It can be seen from the above equation that the individual number of moles are distinct and have just one possible value. And if C₂H₂ is A, O₂ is B, CO₂ is C and H₂O is D, then 4 is "c".

Thus, "c" is the number of moles for the substance "C" with just one possible value.

To calculate the change in entropy when 1 mole of ethanol condenses at its boiling point of 78.3°C, we can use the formula:

ΔS = q/T

where ΔS is the change in entropy, q is the heat of vaporization, and T is the boiling point of ethanol in Kelvin.

First, we need to convert the boiling point of ethanol from Celsius to Kelvin by adding 273.15:

T = 78.3°C + 273.15 = 351.45 K

Then, we can substitute the values:

ΔS = -40.5 kJ/mol / 351.45 K

ΔS = -0.115 kJ/(mol·K)

Therefore, the change in entropy when 1 mole of ethanol condenses at its boiling point is -0.115 kJ/(mol·K). This negative value indicates that the process is exothermic and that the system becomes more ordered.

The boiling point of a pure substance (2-bromo-2-methylpropane) should remain the same if repeated trials are performed with the same sample. The boiling point of a substance is determined by its intermolecular forces and is a constant physical property. As long as the sample remains pure and unchanged, the boiling point should not vary.

Boiling point elevation occurs when a non-volatile solute is added to a solvent, causing an increase in the boiling point of the mixture. In this case, the sample is pure, so no solute is added, and therefore, the boiling point should not change.In real-life experiments, some deviations from the expected boiling point may occur due to impurities, instrumentation errors, or human error.

Answer: Yes, the student is right, one should use pellets of the reactant should be heated and stirred for mixing properly.

Explanation:

In case of smaller particles the surface area that is being exposed increases and the due to this the reaction occurs faster.

Increasing the temperature of the temperature, increases the kinetic energy of the particles which helps in easy mixing of the particles.

Answer:

he mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbons molar mass is 12.011 g/mol, and magnesium's molar mass is 24.3050 g/mol. To see why these elements have different molar masses, we need to remember that the atoms of different elements contain different numbers of protons, neutrons, and electrons, so they have different masses. The atomic masses given in the periodic table inside the front cover of this book represent the different weighted average masses of the naturally occurring atoms of each element. Different atomic masses lead to different molar masses.

For example, the atomic mass of magnesium (24.3050) shows us that the average mass of magnesium atoms is about twice the average mass of carbon atoms (12.011), so the mass of 6.022 x 1023 magnesium atoms (the number of atoms in 1 mole of magnesium) is about twice the mass of 6.022 x 1023 carbon atoms (the number of atoms in 1 mole of carbon). Thus the molar mass of magnesium is 24.3050 g/mol, compared to carbons molar mass of 12.011 g/mol.
