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