what are 17 and 18? Question 17 (10 points) A constant current is passed through a solution of Agt in an electrolytic cell. In 3.0 minutes, 0.65 g of silver is deposited at the cathode. The number of moles of electrons passed into the Agt solution is mole. (Please enter your answer in decimal form, such as 0.021, and keep 2 significant figures.) The total coulombs of charge passed into the Cu2+ solution is C. (Please enter your answer in...
please help me! Enter your answer in the provided box. A constant current is passed through an electrolytic cell containing molten MgCl2 for 15.0 h. If 8.70 x 109 g of Cl, are obtained, what is the current in amperes?
Enter your answer in the provided box. A constant current is passed through an electrolytic cell containing molten MgCl2 for 13.0 h. If 9.80 ×105 g of Cl2 are obtained, what is the current in amperes?
What mass of gold is produced when 7.20 A of current are passed through a gold solution for 37.0 min ? Express your answer with the appropriate units. t Gold Electroplating 6 of 6 Constants| Periodic Table Part A Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au+ solution. The item itself serves as the cathode,...
QUESTION 1 A current of 2.00A was passed through sulfuric acid for 30 mins. How many coulombs were passed through the solution? (electric charge C amperes x second) (3 significant figures, do not use scientific notation)
A current of 3.00 amperes is passed through molten MgBr2 for 1.00 hour. The masses, in g, of Mg and Br2 produced at the cathode and anode, respectively, are Mg Bra O A. 2.72,17.9 OB. 1.36,4.47 O C. 2.72,8.94 O D. 1.36,8.94 O E. 0.680,4.47
1.. An alternating current, when passed through a resistor immersed in water for 5 min, just raised the temperature of the water to boiling point. When a direct current of 4 A was passed through the same resistor under identical conditions, it took 8 min to boil the water. Find the r.m.s. value of the alternating current. Neglect factors other than heat given to the water. If a rectifier type of ammeter connected in series with the resistor read 5.2...
When electricity (the flow of electrons) is passed through a solution, it causes an oxidation-reduction (redox) reaction to occur. If the solution contains a metal cation such as Ag+, the flow of electrons will reduce the silver ion, causing solid silver to plate onto the electrode. The amount of metal plated depends on the number of electrons passed. The total charge of a mole of electrons is 96,485 coulombs (C) and 1 ampere (A) = 1 coulomb/second (C/s) Part A...
