The molecular mass of the compound CO2 is calculate by simply taking the number of atoms of each element and multiplying it by the molar mass of the element on the periodic table.
C = 1 • 12.0 g/mol
O2 = 2 • 16.0 g/mol = 32.0 g/mol
CO2 = 12.0 + 32.0 = 44.0 g/mol.
The formula mass of CO2 is 44.0 g/mol.
Solution:
Using Ideal Gas law:
P1 = 1.45 atm
V1 = 5.15 L
P2 = ?
V2 = 3.43 L
Using Ideal Gas Law, PV = nRT:
Now, the number of moles (n) is the same independent of pressure and distance, so let's say that the temperature is stable since there is no details on the issue. As a consequence,
P1V1 = nRT = P2V2
P1V1 = P2V2
Solve for P2 and you're going to get 2.03 atm. It makes sense as you decrease the amount of the gas by compressing it, which implies that you raise the heat.
2) P = 1.5 atm
T = 301 K
n = 0.785 moles
PV = nRT
V = nRT/P
R = 0.0821 (L*atm)/(mol * K)
Therefore,
V = (0.785 * 0.0821 * 301)/1.5 = 19.4 L
Answer:
Zinc sulfide
Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS.
Explanation:
HOPE THIS HELPS :)
You can use fractional distillation which is when you a liquid from a mixture of two or more liquids. we can use their boiling points, alcohol has a boils at 87 celsius which is lower than waters boiling point, 100 celsius. when bringing the mixture to a boil, alcohol will escape first and be trapped and distilled. when the alcohol is still boiling the temp stays at 87 and doesnt rise. the temp only rises when the alcohol evaporates.
Ammonia
is NH₃. Hydrogen chloride is HCl. Ammonium chloride is NH₄Cl.
NH₃
+ HCl --> NH₄Cl
