Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 … Because it is a polar compound, it can be used to dissolve a number of non-polar substances. Substance #1: lard Substance #2: table salt 2. Answers: 1 Get Other questions on the subject: Chemistry. We usually use a rag with some rubbing alcohol on it to remove the adhesive. By stopped working I mean it won't charge. 70.0 mL b. Ethanol, CH 3 CH 2 OH, also called ethyl alcohol, is a particularly important alcohol for human use. a. ionic bonds b. dispersion forces c. hydrogen bonds d. dipole-dipole attractions e. none of the above. Chemistry, 22.06.2019 07:30, mocjau. I use rubbing alcohol to clean just about everything electronic since a computer tech told me that is what he used. 142 mL c. 403 mL d. 470 mL The molecules remain intact. 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. My fitbit ionic is a little over a year old and out of the blue it stopped working. At the bottom of the page, there will be an option to shut down the watch. When an ionic compound dissolves in water, it dissociates into its ions. Isopropyl alcohol has a molecular formula of C3H8O. a. How many mL of isopropyl alcohol are in a full 1 pint (473 mL) container? 70% Isopropyl rubbing alcohol is equally effective as a disinfectant. 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. substances, such as CH3OH or O2, do not dissociate into ions in aqueous solution. Most molecular substances do not dissociate in water. Why can ionic table salt and covalent rubbing alcohol both dissolve in water? It dries quickly and often is the only way to clean something. 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. 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. Ionic or Molecular? ... Rubbing alcohol is 70.0% isopropyl alcohol by volume. The only active ingredient in Lysol Disinfecting spray is ethanol. I figure it also works for my Fitbit pieces. Remove the screen When my batteries corrode, rubbing alcohol and a toothpick will save the flashlight. Other liquids, for example rubbing alcohol and water, can be mixed with each other. Rubbing alcohol and a rag 1. Before starting this repair, make sure to power your watch down by going to "Settings" then "About". Turn your watch off. Start by cleaning off any old adhesive residue that is around the edge of the frame where the display will sit. NaOH and KOH are ionic compounds that contain OH – ions. 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 … Alcohols are covalent molecules; the –OH group in an alcohol molecule is attached to a carbon atom by a covalent bond.
