🔑:## Step 1: Understanding the Castner-Kellner Cell ProcessThe Castner-Kellner cell is an electrolytic cell used for the production of sodium hydroxide (NaOH) and chlorine gas (Cl2) from concentrated aqueous sodium chloride (NaCl), commonly known as brine. The process involves the electrolysis of brine, where an electric current is passed through the solution to drive chemical reactions at the electrodes.## Step 2: Identifying the Primary Product at the CathodeAt the cathode (the negatively charged electrode) of the Castner-Kellner cell, the primary product is sodium (Na). This occurs because the standard reduction potential of sodium ions (Na+) is such that they are reduced to sodium metal at the cathode. The reaction at the cathode can be represented as: 2Na+ + 2e- → 2Na.## Step 3: Reaction of Sodium with WaterSodium (Na) is highly reactive and immediately reacts with water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction can be represented as: 2Na + 2H2O → 2NaOH + H2.## Step 4: Understanding the Anode ReactionAt the anode (the positively charged electrode), chlorine gas (Cl2) is produced through the oxidation of chloride ions (Cl-). The reaction at the anode can be represented as: 2Cl- → Cl2 + 2e-.## Step 5: Overall Electrochemical ProcessThe overall electrochemical process in the Castner-Kellner cell involves the reduction of sodium ions to sodium metal at the cathode and the oxidation of chloride ions to chlorine gas at the anode. The sodium metal then reacts with water to produce sodium hydroxide and hydrogen gas.## Step 6: Chemical Reactions Summary- Cathode reaction: 2Na+ + 2e- → 2Na- Reaction of sodium with water: 2Na + 2H2O → 2NaOH + H2- Anode reaction: 2Cl- → Cl2 + 2e-The final answer is: boxed{Sodium (Na)}

🔑:## Step 1: Calculate the spring constant (k) using Hooke's LawFirst, we need to find the spring constant (k) using the initial mass and displacement. The formula for Hooke's Law is (F = kx), where (F) is the force applied, (k) is the spring constant, and (x) is the displacement. Since the block is at equilibrium, the force applied by the mass is equal to the weight of the mass, which is given by (mg), where (m) is the mass and (g) is the acceleration due to gravity. For the 4kg block, (F = 4kg times 9.8m/s^2 = 39.2N). The displacement (x = 8cm = 0.08m). So, (39.2N = k times 0.08m). Solving for (k), we get (k = 39.2N / 0.08m = 490N/m).## Step 2: Calculate the initial potential energy of the spring with the 5kg blockWhen the 5kg block is placed on the spring, it will stretch further than 8cm. Let's denote the new displacement as (x_2). The weight of the 5kg block is (5kg times 9.8m/s^2 = 49N). Using Hooke's Law again, (49N = 490N/m times x_2), solving for (x_2) gives (x_2 = 49N / 490N/m = 0.1m) or (10cm). The initial potential energy ((PE_i)) stored in the spring when the 5kg block is at its new equilibrium position is given by (PE_i = frac{1}{2}kx_2^2). Substituting the values, (PE_i = frac{1}{2} times 490N/m times (0.1m)^2 = frac{1}{2} times 490 times 0.01 = 2.45J).## Step 3: Apply the conservation of energy principleAs the block falls, its potential energy ((PE)) is converted into kinetic energy ((KE)). At the lowest point of its fall, just before its direction is reversed, all the potential energy will have been converted into kinetic energy. However, since we're interested in how far it falls before its direction is reversed, we need to consider the point where its velocity is momentarily zero again, which would be back at the equilibrium position for the 5kg block, not the initial displacement. But to find how far it falls from its initial release point (the equilibrium point for the 5kg block) to the point where it stops falling (the lowest point), we actually look at the energy at the highest point (initial release) and the lowest point. The potential energy at the highest point (when it's at rest and just about to fall) is (PE_i = 2.45J), calculated in step 2. At the lowest point, all the potential energy is converted back into potential energy (since the block momentarily stops), but now we're considering the distance from the equilibrium point for the 5kg block to the lowest point. The total energy remains constant, but since we are looking for the distance it falls, we should consider the energy difference as it falls from its equilibrium position.## Step 4: Determine the distance the block fallsHowever, the error in the thought process up to this point has been in calculating and applying the energy principles without directly addressing the question's requirement for the distance the block falls before its direction is reversed. Given the block is at equilibrium with the 5kg mass, and considering it falls from this point, the question actually implies finding the amplitude of the oscillation or the distance from the equilibrium point to the point where it stops falling, which in a simple harmonic motion context, would relate to the energy stored and released. But to directly answer the question based on the energy principle and the given setup: the block's fall is essentially about converting the potential energy at the equilibrium point for the 5kg block into kinetic energy at the bottom of its fall, and then back into potential energy as it reaches its maximum displacement below the equilibrium point. Since the block is in simple harmonic motion, the distance it falls from its equilibrium position to the point where it reverses direction (the amplitude of its motion) can be found by considering the energy stored in the spring at the equilibrium position for the 5kg block and how this energy translates into motion.The final answer is: boxed{0.1}

🔑:## Step 1: Calculate the heat energy required to melt the ice cube at 0°CFirst, we need to calculate the heat energy required to raise the temperature of the ice cube from -15°C to 0°C and then melt it. The energy required to raise the temperature of the ice cube to 0°C is given by Q = mcΔT, where m is the mass of the ice cube (0.045 kg), c is the specific heat of ice (2220 J/kg*K), and ΔT is the change in temperature (0°C - (-15°C) = 15°C). So, Q = 0.045 kg * 2220 J/kg*K * 15 K = 1494.9 J. The energy required to melt the ice at 0°C is given by Q = mL, where m is the mass of the ice cube (0.045 kg) and L is the latent heat of fusion of ice (approximately 334,000 J/kg). So, Q = 0.045 kg * 334,000 J/kg = 15,030 J.## Step 2: Calculate the total heat energy required for the ice cube to reach 0°C and meltThe total heat energy required for the ice cube to reach 0°C and melt is the sum of the energies calculated in Step 1: Q_total = 1494.9 J + 15,030 J = 16,524.9 J.## Step 3: Calculate the heat energy that the water can provideThe heat energy that the water can provide is given by Q = mcΔT, where m is the mass of the water (0.290 kg), c is the specific heat of water (approximately 4186 J/kg*K), and ΔT is the change in temperature. Since we're trying to find the final temperature, we'll use T as the variable for the final temperature. The equation becomes Q = 0.290 kg * 4186 J/kg*K * (25°C - T).## Step 4: Set up the equation for thermal equilibriumAt thermal equilibrium, the heat energy lost by the water equals the heat energy gained by the ice cube. So, we set up the equation: 0.290 kg * 4186 J/kg*K * (25°C - T) = 16,524.9 J.## Step 5: Solve for TNow, we solve the equation for T: 0.290 kg * 4186 J/kg*K * (25°C - T) = 16,524.9 J. Simplifying, we get 1213.004 kg*J/kg*K * (25°C - T) = 16,524.9 J. Then, 30,325.1 J - 1213.004 kg*J/kg*K * T = 16,524.9 J. Rearranging, we get -1213.004 kg*J/kg*K * T = 16,524.9 J - 30,325.1 J. This simplifies to -1213.004 kg*J/kg*K * T = -13,800.2 J. Solving for T, we get T = -13,800.2 J / -1213.004 kg*J/kg*K = 11.37°C.The final answer is: boxed{11.37}
