The sublevel would have electrons with the highest energy is 4p. Therefore, option D is correct.
What is an electron ?The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.
The smallest elemental component of an atom, the electron has a negative charge. In a neutral atom, there are an equal number of protons and electrons. One electron and one proton are all that the hydrogen atom has.
The words electric and ion are combined to form the word electron. In turn, electron is derived from the suffix -on, which is currently used to describe other subatomic particles, such as a proton or neutron.
Thus, option D is correct.

The combustion of propane (C3H8) produces CO₂ and H₂O:
C₂H8 (g) +5O₂ (g) → CO₂ (g) + 4H₂O(g)
The reaction of 5.5 mol of O₂ will produce ____ mol of H2O
Answer:
4.4 moles of water
Explanation:
Propane is C3H8. Is the chemical equation, you wrote C2H8 which is wrong. Type everything properly and give a check before finally posting the question.
The chemical equation that is given, is not properly balanced. The BALANCED equation would be
C3H8 + 5O2 → 3CO2 + 4H2O
From this balanced chemical equation, we see that 5 moles of oxygen produce 4 moles of water.
5 moles of Oxygen → 4 moles of water
1mole of oxygen → [tex]\frac{4}{5}[/tex] moles of water
5.5 moles of oxygen → ([tex]\frac{4}{5}[/tex] × 5.5) moles of water = 4.4 moles of water
∴ The reaction of 5.5 mol of O2 will produce 4.4 mol of H2O. [Answer:]
Answer:
5.5
Explanation:
First, you will need to balance the equation ( the equation in your question is not balanced....typo?)
C2 H8 + 4 O2 ===> 2 CO2 + 4 H2O
Now, from the balanced equation:
O2 : H2O = 4/4 = 1/1
SO 5.5 MOLES OF O2 PRODUCES 5.5 MOLES H20

Divers get "the bends" if they come up too fast because the gas in their blood expands, forming bubbles in their blood. If a diver has 5.0 mL of gas in his blood under a pressure of 250. atm then rises instantaneously to a depth where his blood has a pressure of 50.0 atm, what will the volume of gas in his blood be?
Solve without converting volume into dm³ as it will led into same answer
According to Boyles law
P1V1=P2V25(250)=50V21250=50V_2V_2=25mLAccording to Boyle's law, the volume of gas in his blood will be 25 ml at constant temperature.
What is Boyle's law?
Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.
According to the equation the unknown pressure and volume of any one gas can be determined if two gases are to be considered.That is,
P₁V₁=P₂V₂
substitution gives V₂=250×5/50=25 ml.
Therefore, the volume of gas in his blood will be 25 ml at constant temperature.

Two atoms interact with each other and change as shown by the equation Complete the equation by filling in the missing parts.
Answer: the missing parts are ³₂He
Explanation:
The equation shown represents a nuclear reaction, meaning that, instead of the two hydrogen atoms form a molecule by a chemcial bond between the electrons of the atoms, the nuclei of the two interacting atoms change, leading to a new kind of atoms and particles.
That is mainly indicated by the appearace of the particle ¹₀ n, which is the symbol for a neutron. The superscript 1 to the left of the symbol (letter n) means that the mass number of the neutron is 1, and the subscript 0 to the left of the symbol means that the atomic number of neutron is 0.
To determine the symbol, superscript and subscript needed to complete the missing parts of the equation, you need to do a mass number and atomic number balance.
Mass number balance:
The mass number is the superscript to the left of the symbol of the atom.
Each hydrgogen atom, in the reactant side, contributes a mass number 2, and the neutron on the product side contributes a mass number 1, so the balance is:
2 + 2 = x + 1,
from which you determine that the unknown mass number is x = 4 - 1 = 3.
Atomic number balance
The atomic number is the subscript to the left of the element.
Each hdyrogen atom contributes an atomic number 1, and the neutron contributes 0 atomic number. So, the atomic number balance is:
1 + 1 = x + 0 ⇒ x = 2.
Hence, the unknown atomic number is 2.
Conclusions:
The atomic number of the unknown element is 2, meaning that it has 2 protons.
In a periodic table you find that the element with atomic number 2 is helium, whose symbol is He.
The mass number of this atom of helium is 3, which implies that it has 3 - 2 = 1 neutron.
Using the corresponding notation, the complete equation is:
²₁ H + ²₁ H → ³₂He + ¹₀ p

An increase in blood carbon dioxide content causes hemoglobin to ________. release all bound carbon dioxide molecules bind more oxygen molecules bind more H release more oxygen molecules denature
An increase in blood carbon dioxide content causes hemoglobin to release more oxygen molecules. Details about hemoglobin can be found below.
What is hemoglobin?Hemoglobin is the iron-containing substance in red blood cells that transports oxygen from the lungs to the rest of the body.
Hemoglobin consists of a protein (globulin) and heme (a porphyrin ring with an atom of iron at its centre). This justifies its oxygen affinity.
However, excess carbon dioxide in the blood causes blood pH to decrease, resulting in hemoglobin proteins releasing more oxygen molecules.
