Explanation :
Extraction : It is a separation technique in which one compound is separated from a mixture of compounds.
In a chemical process, the solution may not contain only the desired product but there maybe a mixture of products present.
So, for obtaining the desired product we need to get rid of the other products in a mixture like catalyst (if used), other by products or unreacted starting material.
For a compound to be extracted it has to be soluble in the extracting solvent.
Therefore, this process is based on the miscibility of solute and solvent in a mixture.
Answer:
Avogadro's Law; 15.1L
Explanation:
Boyle's Law- Pressure and volume are <u>inversely</u> related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.
Charle's Law- Gas expands/increases in volume when temperature increases, so they are <u>proportional</u>. We see this in the formula
.
Guy-Lussac's Law- As temperature increases, pressure increases, so they are <u>proportional</u>. We see this in the formula
.
Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula
.
Plugging in the values based on Avogadro's Law, we'll have:

12.6 = 
12.6 x 1.2 = V2
15.1L =V2
Answer:
0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios
Explanation:
How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
Hydrochloric acid = HCl
Hydrogen gas = H2
H = 1+
Cl = 1-
HCL = H2 + Cl2
2HCl = H2 + Cl2
2:1:1
0.80 = 0.40 + 0.40
The molar mass should be 14.898g/mol.
I used the equation 100gx(1/xg/mol)x(1mol/2mol)x(16g/mol+x)/1)=103.7 and solve for x.
I found that equation using stoichiometry and the equation 2m+1/2O2-->m2O
The molar mass of the metal I set to x and the molar mass of the metal oxide is 16+x.
Answer:
457.5kPa
Explanation:
Given data
V1=V2=350mL (<em>fixed volume</em> )
P1=366kPa
T1= 88 degrees Celsius
P2=??
T2= 110 degrees Celsius
For the general gas equation
P1V1/T1= P2V2/T2
V1=V2
P1/T1= P2/T2
Substitute
366/88= P2/110
Cross multiply we have
P2*88=366*110
P2*88= 40260
P2= 40260/88
P2= 457.5 kPa
Hence the pressure will change to 457.5kPa
