Wine goes bad soon after opening because the ethanol ch3ch2oh in it reacts with oxygen gas o2 from the air to form water h2o and acetic acid ch3cooh , the main ingredient of vinegar. Calculate the moles of ethanol needed to produce 0.055mol of acetic acid. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
Answer:
For producing 0.55 mole of acetic acid, 0.55 mole of ethanol is required.
Explanation:
The balanced equation for this reaction is
CH3CH2OH + O2 --> CH3COOH + H2O
As we can see in this equation, the ration of number of moles of acetic acid to the number of moles of ethanal is equal to [tex]1 : 1[/tex]
Hence, in order to produce one mole of acetic acid, 1 mole of ethanol is required.
Thus, for producing 0.55 mole of acetic acid, 0.55 mole of ethanol is required.
2AgF(aq)+Na2CO3(aq)=Ag2CO3(s)+2NaF(aq) net ionic equation
The net ionic equation is applied mainly in neutralization reactions, double displacement reactions and redox reactions. Therefore, the net ionic equation is Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq) [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s).
What is net ionic equation?
The net ionic equation represents a chemical equation of a reaction that give an idea of species that are really participating in the reaction. We can write net ionic equations for those electrolyte which are strong in water.
The balanced net ionic equation is
2AgF(aq)+Na[tex]_2[/tex]CO[tex]_3[/tex](aq)[tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)+2NaF(aq)
Ag⁺(aq) +F⁻(aq) +Na⁺(aq) +CO[tex]_3[/tex]²⁻(aq) [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)+Na⁺(aq) +F⁻(aq)
Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq) [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s)
The net ionic equation cancels out ions that appear on both sides of the reaction arrow because they essentially don't participate in the reaction of interest.
Therefore, the net ionic equation is Ag⁺(aq)+CO[tex]_3[/tex]²⁻(aq) [tex]\rightarrow[/tex]Ag[tex]_2[/tex]CO[tex]_3[/tex](s).

What mass of potassium chloride, KCl, is produced when 12.6 g of oxygen, 02, is produced?
Mass of KCl= 19.57 g
Further explanationGiven
12.6 g of Oxygen
Required
mass of KCl
Solution
Reaction
2KClO3 ⇒ 2KCl + 3O2
mol O2 :
= mass : MW
= 12.6 : 32 g/mol
= 0.39375
From the equation, mol KCl :
= 2/3 x mol O2
= 2/3 x 0.39375
=0.2625
Mass KCl :
= mol x MW
= 0.2625 x 74,5513 g/mol
= 19.57 g

how many moles are in 6.31x10^24 C atoms
Answer:
Explanation:
1 mol of any chemical is 6.02 * 10^23
x mol of any chemical is 6.31 * 10^24
You should look at this before you put it in your calculator. You should think roughly 10.
Now you can set it up as a proportion
1/x = 6.02 * 10^23/6.31 * 10^24 Cross multiply
6.02 * 10^23 x = 1 * 6.31 * 10^24 Divide by 6.02 * 10^23
x = 6.31 * 10^24 / 6.02 * 10^23
x = 10.48 mols.

Much of the water that falls on the ground as precipitation
enters the ground through the process of infiltration
evaporates back into the atmosphere
becomes runoff and finds its way back to the ocean
forms small pools
Answer:
becomes runoff and finds its way back to the ocean
Explanation:
Precipitation refers to rainfall that reaches the earth.
Most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean.
When the rain falls on earth, some evaporates, some enters into the ground while some runs off into rivers and streams. Almost all of the rain water flows into the oceans or other bodies of water.
Hence, most of the rainfall that reaches the earth becomes runoff and finds its way back to the ocean

Explanation:
Electron gain enthalpy is defined as energy released on addition of electron to an isolated gaseous atom.
The amount of energy released will be maximum when the tendency to attract electrons is maximum. As flourine has atomic number of 9 and has electronic configuration of 2,7. It can readily gain 1 electron to attain stable noble gas configuration and hence liberates maximum energy.

The atomic number of an element configuration 2,8, 8,2,13
Answer:
33
Explanation:
The atomic number of an element configuration 2,8, 8,2,13 is 33.
The electron configuration is defined as the arrangement of electrons in atomic or molecular orbitals of an atom. The sum of electrons in different orbitals shown in the electron configuration represents the atomic number of the atom.
So, atomic number of the element configuration 2,8, 8,2,13 is 33.

Suppose you have a mixture of iron filings, sand, and sugar and you want to separate the three. Fill in the materials you expect to see at each step as you perform the actions shown to separate them. The materials you may expect to see are: iron filings, sand, sugar, and sugar water.
Answer:
Explanation:
mixture of iron filings, sand, and sugar
First Step - Iron Fillings
Use a magnet to separate the iron fillings from the mixture. Due to magnetic properties of the iron fillings, the magnets would attract the iron fillings and separate it from the mixture.
Second step - Sand
Place the sand and sugar mixture in water. The sugar would dissolve in water and the sand easily separated by filtration.
Third step - Sugar and Sugar water
Boil the sugar water to remove the water and place in the refrigerator for crystallization of the sugar.
