"basic stamp 2" I’m having a hard time making a code with conditional statements. Please can you help me out Basically it is Since I have three options which are A or B or C I want to to pick let’s say B, so that means I want to open just this one. But I can’t seem to master the IF and ELSE codes as I know I need this ones in the loop Please provide me the code will...

I really need help here, I’m having a hard time even getting started 1. For the diffusion and osmosis lab, you gathered data based on changes in the mass of model cells. To design your experiment, you made educated assumptions about what would pass through the dialysis tubing membrane, and what would not. Using the knowledge you gained during the macromolecules lab, specifically about the reagents that can be used to test for the presence of biological mole cules, give...
Please be extra clear on the molarity and molality questions. I’m having a hard time figuring those two out. Thank you :) 1) An aqueous solution was prepared by dissolving 87.750 g of K2CO3 (potassium carbonate) in 225.00 g of water. It was found that a 10.00-ml sample of this solution had a mass of 12.755 g. (FW of K CO. = 138.204) NOTE: You may often see your instructor use the abbreviation FW, which means Formula Weight. Technically, FW...

Can someone please break down this question for me into parts? I’m having an extremely hard time visualizing everything happening (20 points) Take a ball, with a fan attached to it pointing downward, with a total mass (ball + fan) of 1/5 Kg. This whole arrangement is thrown vertically upward from the edge of a building 50 meters high with an initial velocity of 30 meters/second, with the fan turned on The fan exerts an upward force of (1-e-3) Kg...
