Explanation:
During condensation reaction, two molecules combine to form a single molecule with the loss of a small molecule; in dehydration reaction, this lost molecule is water.
The reaction is a small molecule formed from the atoms removed from a single reactant molecule this reaction is knowing as condensation reaction.
How is the condensation process?Essentially, this is the reverse process of vaporization. In order for water vapor to undergo the process of condensation, which is the change from a gaseous state to a liquid state, it is necessary for a reduction in its temperature to occur until it reaches the dew point or an increase in the pressure to which it is subjected.
In this case the condensation reaction are when two molecules combine to form a single molecule with the loss of a small molecule, in dehydration reaction, this lost molecule is water.

Zn + I2 ---> Znl2
Determine the theoretical yield of the product if 2g of Zn is used
Answer:
Mass = 9.58 g
Explanation:
Given data:
Mass of Zn = 2g
Theoretical yield of ZnI₂ = ?
Solution:
Chemical equation:
Zn + I₂ → ZnI₂
Number of moles of Zn:
Number of moles = mass/molar mass
Number of moles = 2g / 65.38 g/mol
Number of moles = 0.03 mol
Now we will compare the moles of Zn and ZnI₂.
Zn : ZnI₂
1 : 1
0.03 : 0.03
Mass of ZnI₂:
Mass = number of moles × molar mass
Mass = 0.03 mol × 319.22 g/mol
Mass = 9.58 g
A _____________ is formed when water empties into a lake or ocean
Answer:
a delta
Explanation:

100gm of a 55% (M/M) nitric acid solution is to be diluted to 20% (M/M) nitric acid.
How many liters of water should be added to the starting solution?
Volume of H₂O added = 175 ml
Further explanationGiven
100 gm of a 55% (M/M) and 20% (M/M) nitric acid solution
Required
waters added
Solution
starting solution
mass H₂O = 45%=45 g
%mass of H₂O in new solution = 100%-20%=80%
Can be formulated for %mass H₂O :
[tex]\tt \dfrac{45+x}{100+x}=80\%\\\\45+x=0.8(100+x)\\\\45+x=80+0.8x\\\\35=0.2x\rightarrow x=175~g[/tex]
For water mass=volume(density = 1 g/ml)
So volume added = 175 ml
Is Na3PO3 soluble or insoluble in water and why?
Answer:
Na3Po3 is soluble in water
Sodium phosphite, often referred to as [tex]Na_3PO_3[/tex], is generally considered to be water soluble.
Because the sodium cation (Na+) has a significant affinity for water molecules due to their positive charge, sodium compounds generally have a tendency to be soluble in water. The three sodium ions increase the solubility of [tex]Na_3PO_3[/tex] and make it even more soluble.
The solubility of [tex]Na_3PO_3[/tex] is similarly affected by the phosphate ion [tex](PO^3^-)[/tex]. Phosphates are normally soluble in water unless they are coupled with cations that generate intractable compounds, like some heavy metal ions. The strong ion-dipole interactions between sodium ions and water molecules can be used to explain why [tex]Na_3PO_3[/tex] is soluble in water.

Answer:
These cycles are called biogeochemical cycles because they include a variety of biological, geological, and chemical processes. Many elements cycle through ecosystems, organisms, air, water, and soil. ... The biogeochemical cycles transport and store these important elements so that they can be used by living organisms.
A different element, , is located in the same row of the periodic table as element , but has roughly half the atomic mass of . Is the atomic radius of less than, equal to, or greater than the atomic radius of ? Justify your answer using principles of atomic structure.
Answer:
It is way too long I can't help with it Honestly
An element in the same row with roughly half of the atomic mass always has a greater atomic radius.
Atomic radius: It is the distance between the nucleus and the outermost shell.
Atomic mass: It is the mass or the number of nucleons or protons and neutrons inside an atom.
In a row, the number of protons increase but the number of shells remains constant.
Hence, the positive protons in the nucleus attract electrons with more electrostatic force.
Therefore, an element in the same row with roughly half of the atomic mass always has a greater atomic radius.

Which of the following electron configurations correspond to an excited state? Identify the atoms and write the full, ground state electron configuration where appropriate.
1s22s23p1
1s22s2sp6
1s22s22p43s1
[Ar] 4s23d54p1
Electron configurations correspond to an excited state is 1s₂, 2s₂, 3p₁.The electrical configuration 1s₂, 2s₂, 3s₁ demonstrates that the atom is in the excited state.
What is electronic configuration ?The distribution of an atom's or molecule's electrons in atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry.
An electron is in an excited state when it momentarily possesses an energy level higher than its ground state. If an electron receives more energy, such as when it absorbs a photon, or packet, of light, or collides with an adjacent atom or particle, it can become excited.
The primary distinction between a system's ground state and excited state is that a system's ground state is any condition in which its electrons are at their lowest potential energy levels, whereas an excited state is any state in which they are at an energy greater than the system's ground state.
Thus option A is correct.

Which molecules is converted directly to acetyl CoA without the intermediate step of being converted first to pyruvate
Answer:
Fatty acids
Explanation:
Acetyl coA is a compound vital for the process of cellular respiration in the mitochondria. It is the starting material of the kreb's cycle or TCA cycle, which takes place in the mitochondria. During the metabolism of glucose (glycolysis), a molecule called PYRUVATE is first synthesized before becoming acetyl coA in the mitochondrion.
However, the metabolism of FATTY ACIDS (monomers of lipids) directly gives rise to acetyl coA without first becoming pyruvate. The fatty acids molecule undergo Beta- oxidation to produce acetyl coA, which enters the TCA cycle to continue cellular respiration.
