Answer:
- Absolute pressure inside the ball: .
- Number of moles of air particles inside the ball, by the ideal gas law: approximately .
Explanation:
The gauge pressure inside the ball gives the absolute pressure inside the ball, relative to the atmospheric pressure outside the ball. In other words:
.
Rearrange to obtain:
.
Look up the ideal gas constant. This constant comes in a large number of unit combinations. Look for the one that takes for pressure and for volume.
.
Convert the temperature to absolute temperature:
.
Assume that the gas inside this ball acts like an ideal gas. Apply the ideal gas law (after rearranging) to find the number of moles of gas particles in this ball:
.
(Rounded to two significant figures, as in the pressure gauge reading.)
Explanation:
Zn=65
Cl2= 35+35=70
65+70=135g
1 mole ZnCl2 = 135g
x mole = 17.5g
17.5g × 1 mole/ 135g= 0.129 moles en 17.5g de ZnCl2
Isomers are defined as the compounds which have same formula but different in arrangement.
So, Isomers have the same number of atoms in each element.
According to the given examples, CH₃CH₂OH has the chemical formula as C₂H₆O while CH₃CHO has C₂H₅O. So, the number of atoms in each element is different for the given examples. Hence, <u>CH₃CH₂OH and CH₃CHO are not isomers of each other. </u>
No because they can be seperated differently
