Answer:
Australia is correct
Explanation:
Because it is not attached to any other place
Answer: The mass of deposited cadmium is 23.9g
Explanation:
According to Faraday Law of Electrolysis, the mass of substance deposited at the electrode is directly proportional to the quantity of electricity passed through the electrolyte.
Faraday has found that the amount of electricity needed to liberate one gm eq. of substance from an electrolyte is 96500C.
Given that
time (t) =1.55min *60 =93seconds
Current (I) =221A
Q= It = 221 * 93 =20553C
Molar mass of CdS04 =112.41
96500C will liberate 112.41g
20553C will liberate Xg
Xg= (20553*112.41)/96500
=23.9g
Therefore , the amount of Cd deposited at the electrode is 23.9g
Missing question: <span>A 5.00 L sample of O2 at a given temperature and pressure contains a 1.08x10^23 molecules. How many molecules would be contained in each of the following at the same temperature and pressure? </span>
a) 5.00 L H2.
<span>b) 5.00 L CO2.
Use </span>Avogadro's Law: The Volume Amount Law: <span>equal </span>volumes<span> of all gases, at the same temperature and pressure, have the same </span>number<span> of molecules. Because hydrogen and carbon(IV) oxide are gases, number of molecules are the same as number of oxygen molecules, so:
a) N(H</span>₂) = 1.08·10²³.
b) N(CO₂) = 1.08·10²³
