Look at the structure of a soap molecule, and explain what happened when you added soap to your oily hands and put your hands under the water for the solubility lab. Why could you wash the oil off your hands with soap and water? You should use chemistry concepts including structure, polarity, and intermolecular forces to explain your answer. attached is the lewis structure of a basic soap molecule. There are covalent bonds between all carbons, hydrogens, and oxygens. However, there is an ionic bond between oxygen and sodium ions.

Consider the following chart with ionic and covalent compounds shown. Ionic and Covalent Compounds     Compound Melting Point ⁰C Boiling Point ⁰C W 801 1465 X 2852 3,600 Y 0 100 Z 113 184 Based on the data, which compounds would you classify as ionic or covalent and why? A Compound Y is ionic because its’ melting and boiling points are low.   B Compound Y and Z are covalent because their melting and boiling points are low.   C Compounds W, X, and Z are ionic because their melting and boiling points are high.   D Compounds W, X, and Z are covalent because their melting and boiling points are high.

Draw the Lewis structure of these compounds and use the electronegativity values, calculate the polarity of the molecules and write if the compounds will be polar, nonpolar, or ionic. Label the + and -next to the atoms of the molecule if they have charge. Also, write the overall dipole.   Cl₂ HCl NH₃ CH₂O CH₄ O₂ CH₂Cl₂ H₂O CH₃Li HCN CH₂CHCl CH₃CH₃ CO₂

help por favor I just need to draw the molecule

THIS is the equation N2H4 + O2 → N2 + H2O PLEASE HELP AND LOOK AT THE PICTURE FOR DATA  PLEASE HELP! I REALLY NEED HELP BECAUSE MY TEACHER HASENT TAUGHT ME HOW TO DO THIS PLEASE HELP!!!!!   Balance the equation (if not already balanced) Draw the models of the molecules in the equation, using Lewis structures, ball and stick models or something else that represents each of the atoms and how they are connected.  Identify bonds being formed or broken.  Use bond energy values from below to Calculate the overall energy of the reaction. Determine if the reaction is exothermic or endothermic. Draw a potential energy diagram showing the ∆H, reactants and products. Create one example of mass (g) to mass (g) stoichiometry problem.

What is a double bond? What is a triple bond? Compare the bond lengths for single, double and triple bonds between two carbon atoms.

Do question 6 and 7 pleas if you cant do both of them just return the question please

Part A) Consider the structural changes that occur in the following molecules. Begin by drawing the best Lewis Structure for each of the following molecules. BH3 CH4 NH3 H2O HF Part B)What are the ideal bond angles for each structure, and which are expected to be distorted? For the ones that are distorted look up on the internet and record their experimental values here:    Part C)According to Lewis and VSEPR theory, why do these changes occur?

compound hydrogen-bonding force Between Between molecules of formula or Lewis molecules of the the compound and molecules of water? name structure compound? H H | Н — С | | yes yes N-chloromethylamine - no no H. yes yes hydrogen iodide HI no no :0: || н —с —с-о — н H yes yes acetic acid no no H O O

1. What are functional groups? What are some common functional groups and how do functional groups affect the properties of an organic molecule? 2. What is the functional group on each of the molecules above?

TRUE OR FALSE All atoms play a role in the physicochemical and pharmacologic properties of a molecule. Sophistication and advancement in technology are the main driving forces of drug development. Organic medicinal chemistry is the study of matter, specifically, all carbon-containing compounds. A functional group will always have the same physicochemical properties, regardless of its neighboring atoms in a molecular structure. Addition of a single methyl group in a drug molecule may result to changes in physical, chemical, pharmacokinetic, and pharmacologic properties. Steric effects occur when bulky and large functional groups are near each other in a molecular structure. Molecules that are highly capable of hydrogen bonding tend to be more soluble in nonpolar solvents.

For the structure CIO3 draw a Lewis structure using Cl as the central atom... For the structure that obeys the octet rule which of the following are correct? There are a total of 26 valence electrons There are a total of 24 valence electrons There are a total of 25 valence electrons OCI has one lone pair of electrons CI makes a double bond to one of the oxygens Each O has a -1 formal charge 20 atoms make a double bond to Cl All 30 atoms make a double bond to Cl

1. For each pair of elements listed determine if they will form an ionic (I) or covalent (C) bond.    2.General Properties of Ionic and Covalent Compounds (Use THIS LINK to complete the table)  https://www.thoughtco.com/ionic-and-covalent-compounds-properties-3975966

Please note that "geometry" refers to the molecular or ionic geometry. Recall that for predicting geometry, double and triple bonds count as only one electron pair. The Lewis diagram for NOCI is: 6=N_C: The electron-pair geometry around the N atom in NOCI is There is/are lone pair(s) around the central atom, so the geometry of NOCI is The Lewis diagram for CS₂ is: S=C=S The electron-pair geometry around the C atom in CS2 is There is/are lone pair(s) around the central atom, so the geometry of CS2 is

The Lewis structure of N2H2 shows ________.     a nitrogen-nitrogen triple bond     a nitrogen-nitrogen single bond     each nitrogen has one nonbonding electron pair     each nitrogen has two nonbonding electron pairs     each hydrogen has one nonbonding electron pair
