1- Imagine that you are working as a biomedical engineer in the hospital. At an emergency situation somehow, hospital lost all of its equipment for sterilization. However, there are several different types of disinfectants that are not sporicidal at the concentrations that are used for disinfection. You are asked to develop a strategy to sterilize metallic surgical instrument. What would your strategy be? Please explain and give reasons.
ELECTROCHEMISTRY: Calculate the required voltage (V) if an unknown metal (M) was electrodeposited from an aqueous solution containing M2X1 (where X is the anion) with a supplied current of 5.54 A for 11 h, consuming 0.1826 kWh of electrical energy. Assume that the current efficiency is 85%. (Input values only with 2 decimal places. Do not include the unit.)

Uses of Substances based on their Chemical Bonds Objective: To discover the uses of some substances based on their chemical bonds. I. I. Materials: Flashlight bulb 3V -battery Connecting wires (exposed ends) Metal strips of aluminum, copper, iron Distilled water NaCI Small Beaker II. Procedure: 1. To show the conductivity of table salt, NaCl, prepare a simple circuit consisting of a flashlight bulb, 3V- battery, and connecting wires with insulator ends removed. Prepare 200 cc of distilled water in a small beaker and immersed the ends of the connecting wire in the water as shown below. Observe the bulb if it would light. Mix 5 g of NaCl in the distilled water and observe the bulb. Did it light? electrodes wire saltwater battery light bulb 2. Add 5 g more, mix and observe the bulb again. 3. Repeat procedure 2. 4. To illustrate the electrical conductivity of different metals, prepare strips of aluminum, copper and iron. Use the circuit in procedure 1. Connect the bare ends of the wire to…
