Answer:Three identical point charges, Q = 3μC, are placed at the vertices of an equilateral triangle as shown in the figure. The length of each side of the triangle is d = 0.15m. Two equally charged spheres of mass 1.0 g are placed 2.0 cm apart.55) What mass of aluminum can be plated onto an object in 755 minutes at 5.80 A of current? 56) Nickel can be plated from aqueous solution according to the following half reaction. How long would it take (in min) to plate 29.6 g of nickel at 4.7 A?Explanation: where Q= quantity of electricity in coloumbs. I = current in amperes = 5.80 A. t= time in seconds =755 min =. of electricity deposits 1 mole of Al. W is mass of substance liberated or deposited at electrode, Z is electrochemical equivalence, Q is charge flow.A current of 0.80 A was applied to an electrolytic cell containing molten CdCl2 for 2.5 hours. What mass of chromium could be deposited by electrolysis of an aqueous solution of Cr2(SO4)3 for 180.0 minutes using a constant current of 10.0 amperes?Aluminium is the world¡¯s most abundant metal. The versatility of aluminium makes it the most widely used metal after steel. The specifications, properties, classifications and class details are provided for aluminium and aluminium alloys.

Calculates the acceleration of a charged particle when it is placed between two charged plates that are parallel to each other. This is at the AP Physics...When current * time = mole/molar mass * faraday's constant. when the current = 5.8 a. and time = 755 min. mole 3 (Al+3) = 3 moles. molar mass = 27 g/mol. and Faraday's constant = 96500. by substitutionDetermine (a) its mass and (b) its volume if the mass density of aluminum is 2.7gr/cm3. Solution: Two equations can definitely be written down. The sum of masses and the sum of volumes that are given. M = ρV is applicable to both metals: Mgold = ρgoldVgold & Mcopper = ρcopperVcopper.What mass of aluminum can be plated onto an object in 755 minutes at 5.80 A of current? Answer.

Question: What Mass Of Aluminum Can Be Plated Onto An Object In 755 Minutes At 5.80 A Of Current? Please Do Step By Step And As Clearly As Possible.So the total charge in 30 minutes is Q = 5C/s x 30min x 60s/min = 9000C. Then the number of moles of copper plated out (n) is: n = Q/zF where z is the number of electrons in the half-cell reaction (in this case, 2) and F is the Faraday constant = 96 So 2.96 grams are plated deposited at the cathode.

Why is an electron flood gun used in ESCA, Auger, and different surface analysis tools? 2. ESCA and Auger tools are useful for the research of components present in concentrations greater than 1% even if the absolute sensitivity of the method...
