142 mL c. 403 mL d. 470 mL Other liquids, for example rubbing alcohol and water, can be mixed with each other. Isopropyl alcohol has a molecular formula of C3H8O. Ionic or Molecular? Rubbing alcohol and a rag 1. I figure it also works for my Fitbit pieces. a. ionic bonds b. dispersion forces c. hydrogen bonds d. dipole-dipole attractions e. none of the above. According to Ron Kurtis' School of Champions, an educational resource, polarity is the separation of electric charge in molecules that leads the molecules to have specific dipole or multipole movement. It dries quickly and often is the only way to clean something. Ethanol, CH 3 CH 2 OH, also called ethyl alcohol, is a particularly important alcohol for human use. Most molecular substances do not dissociate in water. My fitbit ionic is a little over a year old and out of the blue it stopped working. When an ionic compound dissolves in water, it dissociates into its ions. Because it is a polar compound, it can be used to dissolve a number of non-polar substances. 70.0 mL b. In general rule,polar or ionic substances dissolve in polar solvents and nonpolar substances dissolve in nonpolar solvents.Hydroxyl groups (-OH) is the main factor found in alcohols,they are polar. When my batteries corrode, rubbing alcohol and a toothpick will save the flashlight. In fact it won't even give me a percentage of charge, rather the screen shows the Fitbit image (the diamond-shape dots that are light blue) and stays on … Turn your watch off. 2. Let the alcohol dry off of the unit then put a thin line of T8000 or B7000 Glue around the entire edge of the housing where the screen will sit. Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 … Remove the screen a. How many mL of isopropyl alcohol are in a full 1 pint (473 mL) container? ... Rubbing alcohol is 70.0% isopropyl alcohol by volume. The molecules remain intact. Substance #1: lard Substance #2: table salt NaOH and KOH are ionic compounds that contain OH – ions. 70% Isopropyl rubbing alcohol is equally effective as a disinfectant. At the bottom of the page, there will be an option to shut down the watch. I use rubbing alcohol to clean just about everything electronic since a computer tech told me that is what he used. Chemistry, 22.06.2019 07:30, mocjau. We usually use a rag with some rubbing alcohol on it to remove the adhesive. By stopped working I mean it won't charge. Why can ionic table salt and covalent rubbing alcohol both dissolve in water? Answers: 1 Get Other questions on the subject: Chemistry. Rubbing alcohol Substance #4: Paraffin wax Substance #5: Baking Soda Substance #6: Copper (II) Sulfate Discussion: Based on the observations made and your knowledge of the properties of ionic and molecular compounds, determine which substances are ionic and which are molecular. Before starting this repair, make sure to power your watch down by going to "Settings" then "About". Start by cleaning off any old adhesive residue that is around the edge of the frame where the display will sit. substances, such as CH3OH or O2, do not dissociate into ions in aqueous solution.
