Molecules are related to matter because

1 answer:

8 0

Because matter is made up of molecules, the behavior of matter is dictated by the behaviors of the molecules. If the molecules were different, matter would be different. how is chemistry connected to everyday life? Many of the changes you observe in the world around you are caused by chemical reactions.

Propylene oxide is used to make many products, including plastics such as polyurethane. One method for synthesizing it involves

Vadim26 [7]

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.

Question 22

ruslelena [56]

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:

$n_{CO_2}^{by\ CH_4}=85gCH_4*\frac{1molCH_4}{16gCH_4} *\frac{1molCO_2}{1molCH_4} =5.3molCO_2\\\\n_{CO_2}^{by\ O_2}=320gO_2*\frac{1molO_2}{32gO_2} *\frac{1molCO_2}{2molO_2} =5molCO_2$

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.

If 15 ml of water is added to a solution of hydrochloric acid with a pH of 2, how will the solution change?

Katarina [22]

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:

$[HCl]=[H^+]=10^{-pH}=10^{-2}=0.01M\\$

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!

How are the reactants represented in the chemical equation for photosynthesis? 6co2 o2 6co2 6h2o c6h12o6 6o2 c6h12o6 6h2o

Vika [28.1K]

The reactants of photosynthesis are represented by $6CO_2$ and $6H_2O$ .

<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:

$6CO_2 + 6H_2O --- > C_6H_{12}O_6 + 6O_2$

Thus, the reactants are represented by $6CO_2$ and $6H_2O$ respectively.
