When you connect a battery's two electrodes into a circuit (for example, when you put one in a flashlight), the electrolyte starts buzzing with activity. Slowly, the chemicals inside it are converted into other substances.Ions(atoms with too few or too many electrons) are formed from the m...
Total hip prostheses have undergone several design iterations, beginning with first generation metal-on-metal (MoM) articulations, which were plagued by failure mechanisms including frictional locking and corrosion [1]. These early designs were largely supplanted by prostheses with other bearing surfaces ...
Explain the role of acids in promoting corrosion. Explain how you would prepare 1 L of 1 M HCl from concentrate HCl. Describe the behavior of bromide towards concentrated H_2SO_4. What is Raoult's law? Explain the concept briefly. Explain, with suitable resonating structures, why 4-nitrophe...
a. What is the purpose of a salt bridge? Explain. b. How is the salt bridge prepared in this experiment? Explain the role of electrolytes in promoting corrosion. Is there a salt bridge in a fuel cell? The solution in the salt-bridge is replaced with CH_3OH(aq). Id...
but the channels were rough from years of rust and that corrosion made the diving the planks difficult. To add difficulty to the situation, there is a 2”wide metal plate that runs along both sides of the trailer, front to back. Instead of welding the plate flush to the bottom of the ...
