The mole ratio of acetic acid to water in 100 g of vinegar is 0.015 : 0.985.
<h3>What is the mole ratio of acetic acid to water in 100 g of vinegar?</h3>
The mole ratio of acetic acid to water in 100 g of vinegar is determined from their percentage composition.
The percentage composition of acetic acid and water in vinegar is 5% acetic acid and 95% water.
In 100 g of vinegar, there are 5 g of acetic acid and 5 g of water.
Moles = mass/molar mass
molar mass of acetic acid = 62 g/mol
molar mass of water = 18 g/mol
moles of vinegar = 5/62 = 0.08
moles of water = 95/18 = 5.28
total moles = 5.36
Mole ratio of vinegar to water = 0.08/5.36 : 5.28/5.36
Mole ratio of vinegar to water = 0.015 : 0.985
In conclusion, the mole ratio is determined from the percentage composition of acetic acid and water in vinegar.

Answer:
a) 9424797000 m3
b) 9424797000000 liters
c) 9424797000000 kg
Explanation
Cylinder has a radius of 1 km= 1000 m.
Area Cylinder = π r^2 = 3,141599* (1000m)^2 = 3141599 m2
a) Volume Cylinder= area x Height=3141599 m2* 3000 m= 9424797000 m3
b) 1000 liters= 1m3, 9424797000 * 1000 = 9424797000000 liters
c) densiy = 1000 kg/m3, or 1 kg/ liter, mass= 9424797000 lt * 1kg/lt =
9424797000 kg
Answer: The process by which the particles can reconvene entirely in one of the flasks is: NONSPONTANEOUS.
Explanation:
The spontaneity of a process can affect the distribution of energy and matter within the system. Different chemical or physical processes have the natural tendency to occur in one direction under a given set of conditions. For example:
--> when water is pour down a hill it naturally flows down but it requires outside energy maybe from a water pump to flow up the hill and ,
--> during an iron rust, iron that is exposed to atmosphere will corrode, but rust is not converted to iron without intentional chemical treatment.
Therefore, a spontaneous process is one that occurs naturally under certain conditions. While a NONSPONTANEOUS process, on the other hand, will not take place unless it is initiated by the continual input of energy from an outside source. A process that is spontaneous in one direction under a particular set of conditions is nonspontaneous in the REVERSE direction.
From the two flasks that where connected through a valve, once the valve was opened, the gas spontaneously becomes evenly distributed between the flasks. To reverse this, it would require an external energy making the reconvening of the particles back to the first flask a NONSPONTANEOUS PROCESS .
Answer:
A Petal B Stigma C Stamen
Explanation:
Answer:
The number of neutrons is obtain through the difference of the mass number and the number of electrons
Explanation:
By looking at the periodic table, you will see that Fluorine has 9 protons.
Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.
Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.
As for the atomic number, it is obtainable through the periodic table itself.
