Final answer:
The conductivity of CuCl2 and H4SiO4 refers to their ability to conduct electricity when in solution. The formula to calculate charge is current times time, giving 216 coulombs for a 0.60 A current over 6 minutes through CuSO4. Additionally, 2,261 molecules of CuS are formed from the reaction of 9,044 hydrogen atoms with CuO.
Step-by-step explanation:
The conductivity of CuCl2 and H4SiO4 relates to their ability to conduct electricity when dissolved in water. To find the total number of coulombs of charge that passes through a cell, you can use the formula: charge (Q) equals current (I) times time (t), where time is in seconds. If a current of 0.60 A passes through an aqueous solution, like CuSO4, for 6.0 min (360 seconds), the total charge in coulombs would be 0.60 A * 360 s = 216 coulombs.
As for the chemical reaction CuO(s) + H2S(g) → CuS + H2O(l), we know that each molecule of H2S generates one molecule of CuS upon reaction. To find out how many molecules of CuS are formed from H atoms, we first need to convert atoms to molecules. Since 9,044 atoms of H represent 4,522 molecules (as H is diatomic in its molecular form, H2), and since it takes two atoms of H to react with one molecule of CuO, the number of molecules of CuS formed would be half of the number of H2 molecules, so 2,261 molecules of CuS would be formed.
