Answer:

Blood, bone, tendon, ligament, adipose, and areolar tissues are examples of connective tissues.Explanation:

An equilibrium response is a chemical reaction between the reactants that remains in a solid nation earlier than and after the final touch of the reaction chemical equilibrium, the situation in the path of a reversible chemical reaction wherein no net exchange within the amounts of reactants and merchandise occurs.

Calculation;

Volume(V) = 1.00L

Temperature(T) = 375°C = 648K

Pressure(P) = 226.8 torr × (atm/ 706torr) = 0.298atm

R = 0.08206 atm mole ⁻¹K⁻¹

PV  = nRT

n = PV/RT

= (.208×100)/(.08206×648) = 00561 mole

Mass of powder = 1.00g

1.00/.00561 = 178.2 g/mole

Mass percent C = 94.3% = 94.3g

H = 5.7% = 5.7 g

94.3 × (mole C/12g) = 7.86 mole C

5.7 × (mole H/ 1.0g) = 5.64 mole H

7.86 / 5.64 = 1.4 × 5  = 7;  7(12) + 5(1.01) = 89.05

5.64 / 5.64 = 1 × 5 = 5;  

emp form mass = C₇H₅

178/mole/89.05/mole = 2

(C₇H₅)₂ = C₁₄H₁₀

It may be tempting to assume that after equilibrium has been reached, the response stops. Chemical equilibrium is a dynamic system. The ahead and reverse reactions continue to arise even after equilibrium has been reached. However, because the charges of the reactions are identical, there's no trade inside the relative concentrations of reactants and merchandise for a response that is at equilibrium.

Answer: Milk and chocolate/ oil and water are solution whereas fruit salad and air are mixtures

Lowering the temperature and increasing the pressure of the solution would generally result in a solid coming out of a solution through crystallization.

Crystallization is a process in which a solid forms from a solution by the arrangement of particles into a regular, repeating pattern. Here are the steps involved:

1. Dissolving: Initially, a solute is dissolved in a solvent to form a solution. The solute particles are dispersed and surrounded by the solvent molecules.

2. Saturation: The solution is then brought to a state of saturation by adding more solute or removing the solvent, such that no more solute can dissolve. At this point, the solution contains a high concentration of the solute.

3. Nucleation: When the solution becomes saturated, it becomes unstable, and the solute molecules start to come together and form tiny clusters or nuclei. These nuclei serve as the starting points for crystal growth.

4. Crystal Growth: Once the nuclei form, they start growing as more solute particles join the crystal lattice. This growth occurs by the addition of solute molecules from the solution onto the existing crystal surface.

Now, let's look at how temperature and pressure affect this process:

- Lowering the temperature: Decreasing the temperature of the solution slows down the movement of solute molecules, reducing their kinetic energy. This leads to a decrease in solubility, meaning less solute can remain dissolved in the solution. As a result, excess solute comes out of the solution and starts forming crystals.

- Increasing the pressure: When the pressure of the solution is increased, it compresses the solvent and alters its properties. This compression can enhance the solubility of the solute, allowing it to dissolve more effectively. Consequently, increasing pressure generally inhibits crystallization as more solute remains dissolved in the solution.

Therefore, lowering the temperature favors crystallization by decreasing solubility, while increasing the pressure generally inhibits crystallization by increasing solubility.

The binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond.  Option b

Aminoacyl-tRNA is a complex molecule that plays a crucial role in protein synthesis. It consists of a tRNA molecule covalently linked to an amino acid. The amino acid is attached to the 3' end of the tRNA molecule through an ester bond.

An ester bond is formed between the carboxyl group (-COOH) of the amino acid and the hydroxyl group (-OH) of the ribose sugar at the 3' end of the tRNA molecule. This ester bond is also referred to as an ester linkage. The formation of the ester bond is catalyzed by the enzyme aminoacyl-tRNA synthetase.

The ester bond in aminoacyl-tRNA is essential for protein synthesis. During translation, the aminoacyl-tRNA molecule carries the specific amino acid to the ribosome, where it is incorporated into the growing polypeptide chain. The ester bond is later hydrolyzed, releasing the amino acid for further use in protein synthesis.

In summary, the binding of the amino acid in aminoacyl-tRNA involves the formation of an ester bond between the carboxyl group of the amino acid and the hydroxyl group of the ribose sugar in the tRNA molecule.

Answer:

A because density DOES have a unit

Explanation:

Answer:

The correct answer is "Electrons are transferred in an ionic bond"

Explanation:

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

In conclusion, chemical bonds are made so that atoms can have their entire outer layer, and thus have a stable electronic configuration. In the ionic bond, when the metallic atom has only one electron in its outer layer and the non-metallic one needs an electron to complete its layer; The metallic atom seats its electron to the non-metallic one. In the same way, the electron is shared in the covalent bond in order to achieve equilibrium.  

Then, the main differences between the two bonds are that the ionic bond occurs between two different atoms (metallic and non-metallic), while the covalent bond occurs between two equal atoms (non-metallic). And in the covalent bond there is an electron compartment, while in the ionic bond there is an electron transfer.

So, the correct answer is "Electrons are transferred in an ionic bond"

Answer:

In ionic bonds, an atom donates an electron to another atom to stabilize it. The electron spends more time with the bonded atom.

In covalent bonds, atoms bond by sharing electrons equally.

a) The sphere emits thermal radiation at a rate of 139.75 Watts.

b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.

c) The sphere's net rate of energy exchange is 102.09 Watts.

To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.

a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:

Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))

Plugging in the given values:

Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)

Emitting Rate ≈ 139.75 Watts

b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:

Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))

Plugging in the given values:

Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)

Absorbing Rate ≈ 37.66 Watts

c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:

Net Rate = Emitting Rate - Absorbing Rate

Net Rate = 139.75 Watts - 37.66 Watts

Net Rate ≈ 102.09 Watts

Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.

Note: The units for all the rates are Watts.
