Answer the following questions showing all your work in Word form.
Question 1
What is the enthalpy change when 50 grams of ice at -10°C is heated to become water at 30°C? Please show all work, including a heat curve for this example.
Your response must be at least 75 words in length.
Question 2
Pick a substance (compound or mixture) and describe the intermolecular attractive interactions that exist between molecules or ions based on their composition and molecular structures.
Your response must be at least 75 words in length.

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 the octet rule.
Requirements:
Central Theme: At the center of your concept map, place the theme “Molecular Geometry and Bonding Theories.” This will be the starting point of your concept map.
Branching Concepts:
Branch out to include major concepts covered in the unit, such as:
Types of Chemical Bonds (Ionic, Covalent, Metallic)
Lewis Symbols and the Octet Rule
Ionic and Covalent Bonding
Bond Polarity and Electronegativity
Lewis Structures and Resonance Structures
Molecular Shapes and VSEPR Model
Bond Strength (Bond Enthalpy) and Multiple Bonds
Hybrid Orbitals and Molecular Orbitals
Sub-Branches: For each major concept, create sub-branches to explore specific details or examples. For instance, under “Bond Polarity and Electronegativity,” you could include examples of polar and nonpolar molecules, along with how electronegativity differences determine bond polarity.
Connections: Clearly indicate the relationships between different concepts. Use arrows or lines to connect related concepts and include brief explanations of how they are connected.
Visuals: Incorporate symbols, illustrations, or icons to represent different concepts where possible. This could include drawing Lewis structures, molecular shapes, or even simple icons to represent electronegativity and bond types.
Creativity and Clarity: While the accuracy of the content is crucial, the layout and design of your concept map are also important. Ensure your map is easy to follow, with a logical flow from one concept to the next. Be creative in how you visualize and connect the concepts.
Submission Guidelines: Your concept map can be created digitally using software like MindMeister, Coggle, or Lucidchart, or hand-drawn and scanned as a clear, high-resolution image.
Submit your concept map as a PDF (for digital maps) or JPEG/PNG (for scanned hand-drawn maps).
Include a brief (200-300 words) reflection on what you learned while creating the concept map and how it helped you understand molecular geometry and bonding theories better. No references or citations are required.
Evaluation Criteria: Your concept map will be graded based on the completeness and accuracy of the information, creativity and clarity in presenting the information, the logical organization of concepts, and the depth of your reflection piece.

Sorry I need to receive the results within 90 minutes.
Use the following information to deduce the structure of metabolites A-D(draw a structure), giving the key information which helped you make your deduction.
(5 marks per metabolite; 2 marks for structure and 3 x 1 mark for reasoning)

Hello, here I attached all slides, guide, and procedure of the experiment. In the SDS slides are the descriiption of the lab report as well as what it should contain. As well as ,I create a word document where you can find more examples about how figures in the results should be labeled and how the discussion should looks like. It should have a graph as well about the Broadford data. I also put a example of how the graph should look like. You can use any format and please email me if you need extra information, document or data.
Please note that the methods should be really simple and no too long ( see the details in the same SDS document.)
Thank you so much and please work in this paper as if will be yours. I will appreciate that
