Need help with my chemistry lab Percent Concentration of NaCl Solution 

After making 300ml salt solution (sufficient amount of salt in each container until there is undissolved salt at the bottom), divide this solution into three (100ml) parts and place in cup A, Cup B and Cup C. You should have 3 samples A (ice water bath) , B (room temperature

Create a detailed concept map that visually explores the relationships and principles of molecular geometry, bonding theories (ionic, covalent, and metallic bonds), bond polarity, electronegativity, and the VSEPR model. Your concept map should also incorporate the concepts of Lewis structures, resonance structures, bond strength (bond enthalpy), and the exceptions to

You will be using a sharp object to cut the stem of your plant. Please take appropriate care and caution. Do not cut any plant stems you cannot identify to avoid allergic reactions. Assignment Description: The course project is designed to focus on experimental design. As future scientists, this project orients
