The phase development of the eutectic reaction includes the equilibrium point of Liquid, crystals of A, and crystals of B

<h3>What is the Eutectic Reaction?</h3>

This refers to the three-phase reaction that occurs when a liquid forms after cooling.

Hence, we can see that the hypo eutectic reaction occurs when there is a homogenous mixture of substances that undergoes a reaction where it melts and solidifies.

The hyper eutectic reaction has to do with the metallic alloy that contains a composition that has exceeded its eutectic point.

What is the reaction used to join the fatty acid to the glycerol molecule?
m_a_m_a [10]

Answer:

The reaction that is used to join fatty acid and glycerol is known as Lipogenesis.

Explanation:

Lipogenesis is an important anabolic pathway that helps in the biosynthesis of triacylglycerol by joining glycerol with fatty acid by ester linkage.Lipogenesis occur in liver and adipose tissue .

             Lipogenesis takes place in our body to store excess fatty acid in form of triacylglycerol which is a complex lipid molecule.

12. A helium-filled weather balloon has a volume of 2.4 x 102 L at 99 kPa pressure and a
Luba_88 [7]

Answer:

The answer to your question is 8.74 g of He

Explanation:

Data

V = 2.4 x 10² L

P = 99 kPa

T = 0°C

mass = ?

Process

1.- Convert kPa to atm

P = 99 kPa = 99000 Pa

                   1 atm --------------- 101325 Pa

                    x       ---------------   99000 Pa

                   x = (99000 x 1) / 101325

                   x = 0.977 atm

2.- Convert temperature to °K

°K = 273 + 0

°K = 273

3.- Substitution

      PV = nRT

- Solve for n

      n = PV / RT

      n = (0.977)(2.4 x 10²) / (0.082)(273)

      n = 24.48 / 22.386

      n = 1.093 moles

4.- Calculate the grams of He

          8 g -------------------- 1 mol

           x    -------------------- 1.093 moles

           x = (1.093 x 8) / 1

           x = 8.74 g

Give an example of a state function and explain why it is a state function
inessss [21]
  • A specific state which is defined being a property without the path taken to achieve that state based on it, is understood as a state function. 
  • While the functions whose value is based on the direction taken among two states are named direction or path functions, on the other hand.
  • The system's thermodynamic condition relates to the current material in temperature, pressure and quantity.
  • State functions rely only on certain requirements and not on how they have been achieved. State functions for an instance, involve entropy, density, enthalpy and internal energy.
  • They are known as state functions as they quantitatively define a thermodynamic system's equilibrium condition, regardless of how the system landed in that condition.
