Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.
<h3>What is Lewis dot structure?</h3>
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.
Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Answer:
O2, oxygen.
Explanation:
Hello.
In this case, for the undergoing chemical reaction, we need to compute the moles of CO2 yielded by 85 g of CH4 (molar mass = 16 g/mol) and by 320 g of O2 (molar mass 32 g/mol) via the following mole-mass relationships:

Considering the 1:2:1 among CH4, O2 and CO2. Therefore, since 320 g of O2 yield the smallest amount of CO2 we infer that the limiting reactant is O2.
Best regards.
This is a guess, but I think it could be the lack of limiting factors.
Answer:
pH of the solution will slightly increase as it becomes less acidic for which it turns out to be more diluted.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the pH change of the solution by firstly calculating the HCl concentration, as equal to that of the hydrogen ions whose pH is 2 as this is a strong acid:
![[HCl]=[H^+]=10^{-pH}=10^{-2}=0.01M\\](https://tex.z-dn.net/?f=%5BHCl%5D%3D%5BH%5E%2B%5D%3D10%5E%7B-pH%7D%3D10%5E%7B-2%7D%3D0.01M%5C%5C)
Now, since water is added to the solution, but we do not have the initial volume of this solution, we can ensure that its pH will increase, become less acidic, because the concentration of the acid, and consequently that of the hydrogen ions, is diminished as the volume is increased.
Best regards!

<h3>Photosynthesis</h3>
It is a reaction through which green plants make use of inorganic products such as water and carbon dioxide in the presence of solar radiation to make sugar. Oxygen is liberated as a by-product.
The equation of the reaction is represented by:

Thus, the reactants are represented by
and
respectively.
