There are some methods that differentiate waves; one thing is by its medium.
Electromagnetic waves did not require a medium for transmission such as in a
vacuum while mechanical waves require a medium to travel such as air, water or
anything that can serve as a transmission aid.
The most common sample of EM waves in
telecommunication is radio,
light and infra-red signals. An example of a mechanical wave is a sound
wave, which requires air to travel. Oscillating molecules made the
sound waves.
Answer:
2C4H10 + 13O2 → 8CO2 + 10H2O
Explanation:
These coefficients satisfy the law of conservation of mass, meaning there are the same number and type of each atom on both sides of the reaction.
Answer:
1) Separate the aqueous layer from the organic layer using the separation funnel.
2) Treat the aqueous layer to obtain compound A.
3) Distilated the organic layer to obtain compound B.
Explanation:
When <u>NaOH is added</u> to the mixture the acid groups will react to produce a salt and increases the polarity of the compounds due to the net charges generated. (Figure 1).
Therefore, the salt produced by compound A will move to the <u>aqueosus layer</u>. Compound B dont react due to the lack of <u>acid groups</u>. So, this molecule will stay in the <u>organic layer</u>.
When the aqueous layer is separated from the organic layer using the separation funnel we will have a <u>separation</u>. The compound will remain in the aqueous layer and compound b will remain in the organic layer.
Then we aqueous layer can be <u>treated with HCl</u> in order to obtain the initial A molecule, in other words: Undo the ionic form of compound A.
The organic layer can be removed by <u>distillation</u> in order to obtain the pure form of compound B.
Conversion factor : molar mass/molecular weight
Mass of H₂O produced = 72 g

Given
Reaction
2H2 + O2- 2H20
8 grams of H2
Required
Conversion factors
Solution
We can use the molar mass of the components and the mole ratio as conversion factors for the above equation
mol H₂ (MW = 2 g/mol) :
From the equation, mol ratio of H₂ : H₂O = 2 : 2, so mol H₂O = 4 mol
mass H₂O(MW = 18 g/mol) :
mass = mol x MW
mass = 4 x 18
mass = 72 g
Answer and Explanation:
The water is a polar solvent which dissolves into the LiBr molecules and converts into 
and 
ions far from the solid also into the solution, when they are hydrated.
Now, the complete words are as given below:-
The 
and 
ions at the surface of the solid are pulled into the solution by the polar water molecules, where the hydration process surrounds separate ions with water molecules.
