Energy diagram which is relative to the energy level of the reactants is attached in the picture below.
What is an energy level?Electrons present in an atom revolve in different orbits which are stationary states and are also called as energy levels. The energy levels are numbered as integers which are also called as principal quantum numbers.
Energy of the stationary state is given as E= -R
1/n² where R
is the Rydberg's constant. When an electron is excited, and it moves from lower to higher energy levels there is absorption of energy, while when it moves from higher energy level to lower energy level it radiates or gives out energy in the form of radiation.
They can also be defined as the distances between electron and nucleus of an atom . Electrons present in K energy level have least energy .Energy level diagrams are studied to understand nature of bonding , placement of electrons in orbits and and elemental behavior under certain conditions.

HELP!! When nitroglycerin (C3H5N3O9) explodes, it decomposes into the following gases: carbon dioxide, nitrogen, nitrogen monoxide, and water vapor. If 239g of nitroglycerin explodes, what volume of water vapor will be produced at 45.00 inHg and 2678C?
Answers
Answer:
Carbon monoxide, and water vapor was analyzed and found to contain 4.5 mol of carbon dioxide, 4.0 mol of carbon monoxide and 1.5 mole of water vapor. ... An ideal gas sample weighing 0.548 g at 100°C and 0.993 atm has a volume of 0.237 ... VSEPR predicts that an IF5 molecule
Explanation:
The volume of the nitroglycerin exploded can be calculated using the ideal gas equation. Here, the number of moles of water vapor formed is 10.5 moles. Then, the volume is 43807 L.
What is ideal gas equation ?Ideal gas equation connects the pressure, temperature and volume of a gas with its number of moles as written in the expression below:
PV = nRT.
where R = 0.082 L atm /K mol
One mole of nitroglycerin produces 10 moles of water. Then, 239 g or 1.05 moles produces 10.5 moles of water vapor.
Given,
P = 45 mmHg = 0.05 atm
T = 2678°C = 2951 K
n = 10.5
The volume of water vapor is calculated as follows:
V = nRT/P
= (10.5 mol × 0.082 L atm/K mol ×2951 K)/0.05 atm
= 43807 L.
Therefore, the volume of water vapor produced is 43807 L.

Energy is transferred from one place to another in the form of waves. Waves has two parts, the highest part of a wave is called the crest, whereas the lowest part is called trough. The distance between the crest and the trough of a wave is known as wave height. When we drop something in the water, waves are produced having high crest and trough means high wave length whereas waves produced on the solid body has low crest and trough means low wave height.

Answers
Answer:
In humans, up to ten different proteins can be traced to a single gene. Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren't all produced by all the body's cells at any given time. Cells have different proteomes depending on their cell type.
Explanation:
Proteins are macromolecules that are complex structures made of monomeric units. There are 20,000 - 60,000 different kinds of proteins in the human body.
What are proteins?Proteins have been the large molecules (macromolecules) that are structurally composed of the monomers or the smaller units. They have been composed of amino acids.
The amino acids are produced by the translational process and are linked by the peptide bonds. They are the most essential compound for the cellular and physical activity of the cells in living organisms.
The proteome is used to identify and classify the various proteins that can range from 20,000 - 60,000 in a human body. These proteins are involved in performing the functions in the body.
Therefore, approximately 20,000 - 60,000 proteins are found in the human body.

HELP ASAP!!!
Answers
Answer:
5moles
Explanation:
number of moles=mass/molar mass
The molar mass of water is 18.0 g/mol. A mass of 90.0 grams of water is equivalent to 5 moles. Therefore, option B is correct.
What is molar mass ?The mass in grams of one mole of a substance is defined as its molar mass. Molar mass is measured in grams per mole, abbreviated as g/mol. The isotopic atomic mass of a single isotope of any given element is a value that compares the mass of that isotope to the mass of the isotope carbon-12.
A compound's molar mass can be calculated by adding the standard atomic masses (in g/mol) of its constituent atoms.
A compound's molar mass indicates the mass of one mole of that substance. In other words, it tells you how many grams of a compound there are per mole. As a result, the units for molar mass are grams/mole.
number of moles = mass / molar mas
= 90.0 grams / 18.0grams
= 5 moles
Thus, option B is correct.

(chem) which is more concentrated: 45.0 grams of HCOOH dissolved in 189 mL of water or 1.5 moles of CH↓2COOH dissolved in twice as much water?
Answers
Answer:
CH3COOH would be more concentrated
Explanation:
The higher the concentration value, the more concentrated it is.
The relationship between concentration, moles and volume is given by the equation;
Concentration = No of moles / Volume
5.0 grams of HCOOH dissolved in 189 mL of water
Number of moles = Mass / Molar mass = 5 / 46.03 = 0.1086 mol
Concentration = 0.1086 / 0.189 = 0.5746 mol/L
1.5 moles of CH3COOH dissolved in twice as much water
Volume = 2 * 189 = 378 ml = 0.378 L
Concentration = 1.5 / 0.378 = 3.9683 mol/L
Comparing both concentration values;
CH3COOH would be more concentrated

How many electrons will aluminum gain or lose in forming an ion?
Answers
Answer:
It would tend to gain one electron and form a -1 ion. Aluminum is in the fifth column and therefore has 5 electrons in its outermost shell. It would tend to lose three electrons and form a +3 ion.
Explanation:
If helpful, please mark as brainliest! =)
Aluminum (Al) is an element with atomic number 13, which means it has 13 protons and 13 electrons in its neutral state.
How does aluminum form ionWhen forming an ion, aluminum tends to lose three electrons. This is because aluminum belongs to Group 13 in the periodic table, also known as the "boron group" or "Group IIIA."
Elements in this group have three valence electrons in their outermost energy level. To achieve a stable electron configuration, aluminum can lose these three valence electrons, leaving behind a complete inner electron shell and forming a 3+ cation.
So, when aluminum forms an ion, it loses three electrons to become Al3+.

Liquid - the molecules are close but not touching about mid way(not to far not to close)

Explanation:Ap3x
The correct statement about the viscocity of the maple syrup is that the Molecules that make up maple syrup have a harder time moving past one another because they are larger than the molecules that make up orange juice.
What is viscosity?The resistance of a fluid (liquid or gas) to a change in shape or movement of adjacent sections relative to one another is called viscosity. Viscosity indicates resistance to flow.
The Molecules that make up maple syrup have a harder time moving past one another because they are larger than the molecules that make up orange juice is correct as it is related to movement.The molecules that make up maple syrup are positive ions, while the molecules that make up orange juice are negative ions as viscosity is not related to the charge.The molecules that make up maple syrup have a harder time moving past one another because they are smaller than the molecules that make up orange juice is incorrect because the small molecules relatively have great movement.The molecules that make up maple syrup are negative ions, while the molecules that make up orange juice are positive ions is also wrong.Hence the correct statement is that the Molecules that make up maple syrup have a harder time moving past one another because they are larger than the molecules that make up orange juice.

Pressure of the gas is defined as the force exerted by the particles on the walls of the container. It is expressed in various terms like 'mmHg', 'atm', 'kiloPascals' etc..
All these units of pressure are inter convertible.
Pressure of the gas = 4.59 mm Hg
