If a feather and a bowling ball were dropped in a vacuum(only gravity effects the variables), they will hit the ground at the same time. So if the mass keeps changing it, and the pod keeps stopping at different points it will take longer to accelerate or decelerate. I’m not totally sure, but here is an answer.
what is the main difference between sexual and asexual reproduction
Answers
Answer:
Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.
The main difference between sexual and asexual reproduction is that sexual reproduction involves the fusion of gametes, while asexual reproduction does not.
In sexual reproduction, offspring are produced through the fusion of gametes (reproductive cells) from two parent organisms. This fusion, known as fertilization, results in offspring that inherit genetic material from both parents. This genetic recombination introduces variation in the offspring, promoting genetic diversity within a population.
In contrast, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. A single parent organism reproduces by generating genetically identical or near-identical offspring through various methods such as budding, fragmentation, or binary fission. Asexual reproduction typically leads to offspring that are genetically identical to the parent, lacking the genetic diversity observed in sexual reproduction.

A chemist makes a solution of zinc acetate by dissolving 20.5 g Zn(C₂H₃O₂)₂ in 105 mL H₂O. What is the concentration of this zinc acetate solution?
Answers
The concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M
We'll begin by calculating the number of mole in 20.5 g of Zn(C₂H₃O₂)₂Mass of Zn(C₂H₃O₂)₂ = 20.5 g
Molar mass of Zn(C₂H₃O₂)₂ = 65 + 2[(12×2) + (3×1) + (16×2)]
= 65 + 2[59]
= 183 g/mol
Mole of Zn(C₂H₃O₂)₂ =?Mole = mass / molar mass
Mole of Zn(C₂H₃O₂)₂ = 20.5 / 183
Mole of Zn(C₂H₃O₂)₂ = 0.112 mole Finally, we shall determine concentration of Zn(C₂H₃O₂). This can be obtained as follow:Mole of Zn(C₂H₃O₂)₂ = 0.112 mole
Volume = 105 mL = 105 / 1000 = 0.105 L
Concentration of Zn(C₂H₃O₂)₂ =?Concentration = mole / Volume
Concentration of Zn(C₂H₃O₂)₂ = 0.112 / 0.105
Concentration of Zn(C₂H₃O₂)₂ = 1.067 MTherefore, the concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.
Thus, all the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

why do we adjust coefficients when balancing chemical equations and not subscripts?
Answers
Answer:
By changing the coefficients you change the amount you have of certain compounds in the equation, whereas changing the subscript would change what compounds are actually in the equation because it would change the ratio of how many atoms of each element are in a compound.
For Example:
Outside of Balancing Equations, [tex]NO_{2}[/tex] (Nitrite) and [tex]NO_{3}[/tex] (Nitrate) are different because one forms a strong acid while the other forms a weak acid based on how many oxygen atoms are added to the compound. So in a chemical equation, if you change the subscripts, you change the entire compound so your reaction may be with a weak acid instead of a strong acid and give you a different product. Meanwhile, changing the coefficient changes the amount of the compound you have for the reaction in order to maintain the Conservation of Mass Law.

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Group 18; The Noble Gases contains the elements on the periodic table that would be the least reactive out of all the elements. So, this include any gas element, such as helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). Hence, if you have the options:

Considerando la definición de molaridad, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].
La molaridad es una medida de la concentración de un soluto en una disolución que se define como el número de moles de soluto que están disueltos en un determinado volumen.
La molaridad de una solución se calcula dividiendo los moles del soluto por el volumen de la solución:
[tex]Molaridad=\frac{numero de moles de soluto}{volumen}[/tex]
La Molaridad se expresa en las unidades [tex]\frac{moles}{litro}[/tex].
En este caso, sabes que una solución acuosa se preparó al mezclar 4 moles del ácido con suficiente agua hasta completar 8 litros de solución. Entonces, sabes que:
número de moles de soluto= 4 molesvolumen= 8 litrosReemplazando en la definición de molaridad:
[tex]Molaridad=\frac{4 moles}{8 litros}[/tex]
Resolviendo:
Molaridad= 0.5 [tex]\frac{moles}{litro}[/tex]
Finalmente, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

in a battery that uses a licoo2 cathode approximately 50% of the lithium migrates from the cathode to the anode on charging. in a battery that uses a limn2o4 cathode what fraction of the lithium in limn2o4 would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode?
Answers
Answer:
92.4%
Explanation:
Assume 100g of the cathode material. The LiCoO2 cathode has 7.09 g of Li. If half of Li migrates during charging, 3.55g Li migrates. 100g of the LiMn2O4 cathode contain 3.84g of Li. The fraction of lithium in LiMn2O4 that would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode:
(3.55g/ 3.84g ) * 100% = 92.4%
From electrolysis, 92.4% would need to migrate out of the cathode to deliver the same amount of lithium to the graphite anode.
What is electrolysis?
Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential.
