What is an orbital? How does it differ from an orbit?
Answer:
An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion. An orbital can simply be defined as space or the region where the electron is likely to be found the most.
Explanation:
Answer:
An orbital on the other hand is simply the probable area where one can expect to find the maximum density of electron presence within an atom. An orbit on the other hand is simply present in a body with a certain mass, while an orbital exists for an electron as well as an atom.
Thus, these are the simple differences between Orbit and Orbitals. It is important to know the major differences, you can check out the differences between Orbit and Orbitals below:
Differences between Orbit and Orbitals
Orbit Orbitals
An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.
It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus An orbital can simply be defined as the space or the region where the electron is likely to be found the most.
The shape of molecules cannot be explained by an orbit as they are non-directional by nature. The shapes of the molecules can be found out as they are directional by nature.
An orbit that is well-defined goes against the Heisenberg principle. An ideal orbital agrees with the theory of Heisenberg’s Principles.
Thus, these are the major differences between Orbit and Orbitals.
Explain cell division in multicellular organisms?
Answer:
the divide through osmosis of mitosis or sum
Explanation:
Answer:
In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. For growth to occur in living organisms, the number of cells have to increase through cell division until it reaches its maximum size. The human body also repairs injuries by means of cell division.

What is the molarity of a solution
made by dissolving 18.9 g of
ammonium nitrate (NH4NO3) in
enough water to make 855 mL of
solution?
Molar Mass N: 14.01 g/mol
Molar Mass H: 1.008 g/mol
Molar Mass O: 16.00 g/mol
Answer:
Molarity = 0.28 M
Explanation:
Given data:
Mass of NH₄NO₃ = 18.9 g
Volume of solution = 855 mL (855mL × 1 L/1000 mL = 0.855 L)
Molarity of solution = ?
Solution:
Number of moles of NH₄NO₃:
Number of moles = mass/molar mass
Number of moles = 18.9 g/ 80.043 g/mol
Number of moles = 0.24 mol
Molarity:
Molarity = number of moles of solute / volume in L
Molarity = 0.24 mol /0.855 L
Molarity = 0.28 M
Answer:
0.28

For the cold pack shown below, the temperature on the outside surface has dropped considerably from its initial temperature of 25 °C. Which of the following provides the best explanation for this temperature decrease?
Answer:
The correct answer is D
Explanation:
In an endothermic process, energy travels from the surroundings into the system. The decrease in the temperature on the outside of the bag indicates that energy has moved from the surroundings into the system.
The other answers are incorrect. A bag cannot release “cold” into the surroundings since cold refers to the absence of heat. The surroundings become colder when heat is removed. Option B is incorrect because the cooling is due to the cold pack absorbing heat energy from its surroundings. Option C is incorrect because a cold pack absorbs heat energy from the surroundings, not vice versa.
The surroundings are losing energy and the thermometer is measuring the temperature of the surroundings as the cold pack shows an endothermic process. Therefore, Option (D) is correct.
What is an endothermic reaction?Endothermic reactions are those in which the reactants absorb heat energy from their surroundings to form products. Endothermic reactions reduce the temperature of their surroundings and create a cooling effect. Physical processes can be endothermic in nature as well, for example, ice cubes absorb heat from their surroundings to form liquid water.
Endothermic reactions include the making of chemical bonds through the absorption of energy from the surroundings. On the other hand, exothermic reactions are in which the liberation of heat energy is generated from bond breakage.
The temperature of the cold pack is lower than the temperature of the surroundings. So the heat energy will be traveled from the surroundings to the cold pack.
Therefore, the temperature of the surroundings will fall as heat transfers to the cold pack.

Aluminum metal reacts with hydrochloric acid to produce solid aluminum chloride and hydrogen gas. how many moles of aluminum are needed to produce 1.2 moles of hydrogen gas?
Moles of Aluminum needed : 0.8
Further explanationGiven
1.2 moles H₂
Required
moles of aluminum
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the components of the compounds involved in the reaction (reactants and products)
Reaction(balanced equation)
2Al + 6 HCl = 2AlCl₃ + 3H₂
From the equation, mol ratio of Al : H₂ = 2 : 3, so mol Al :
= 2/3 x mol H₂
= 2/3 x 1.2
= 0.8 moles

A gas with a volume of 2 L at 25°C is placed into a container that is 4 L. What is the new temperature of the gas?
Given :
A gas with a volume of 2 L at 25°C is placed into a container that is 4 L.
To Find :
The new temperature of the gas.
Solution :
Since, their is no information regarding pressure. We will assume that pressure is constant.
Now, we know when at constant pressure, volume is directly proportional to volume.
[tex]\dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}\\\\\dfrac{2}{4} = \dfrac{25 + 273 }{x}\\\\x = 2 \times ( 25 + 273 )\\\\x = 596\ K[/tex]
Therefore, the new temperature of the gas is 596 - 273 K = 323 K.

A 0.200 M NaOH solution was used to titrate a 18.25 mL HE
solution. The endpoint was reached after 31.20 mL of titrant
were added. Find the molar concentration of the original HF
solution.
Answer:
M₂ = 0.34 M
Explanation:
Given data:
Molarity of NaOH =M₁ = 0.200 M
Volume of HF =V₂= 18.25 mL
Volume of NaOH added = V₁ = 31.20 mL
Molarity of HF solution = M₂ = ?
Solution:
M₁V₁ = M₂V₂
by putting values,
0.200 M × 31.20 mL = M₂ × 18.25 mL
M₂ = 0.200 M × 31.20 mL / 18.25 mL
M₂ = 6.24 M.mL / 18.25 mL
M₂ = 0.34 M
