In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchangingelectronsbe...

a. Write the reaction between formic acid and water. b. What is the pH of a 0.05 M solution of formic acid? c. What is the % dissociation for formic acid? What compound produces hydroxide ions when dissolved in water? Calculate the pH of a soluti...
Determine if the given compound acts as a Lewis base, a Bronsted-Lowry base, both, or neither. Classify the following substances as a Bronsted-Lowry acid, Bronsted-Lowry base, Lewis acid, and/or Lewis base. HCl, BF_3, CCl_3, -H CH_2O, ...
A Brnsted-Lowry acid is defined as a compound that gives hydronium ions to another compound—for example, hydrochloric acid gives H+ ions to compounds it reacts with. Brnsted-Lowry bases are compounds that can accept hydronium ions—when ammonia gets a hydronium ion from HCl, it forms the ...
Question: What is HCl gas? Answer and Explanation:1 Chemical compounds are created when two or more chemical elements bond together. Each chemical compound has a specific chemical formula. For example,... Learn more about this topic: Hydrochloric Acid | HCl Formula, Chemical Properties & Uses ...
Probably this brown/orange/yellow compound is very similar to what you have made by electrolysis. http://www.woelen.nl/chem/exp0005/exp0005.htmThe yellow stuff is a copper (I) compound. When some concentrated HCl is added to the yellow stuff, then a dark solution is obtained, which ...
Zinc chloride (ZnCl2) is a compound of chlorine and zinc. It is colorless or white in appearance, highly soluble in water, and hygroscopic. It should..
such as the metal ion in a carbonate compound. In this case, the chloride ion will combine with the calcium ion, to make the compound calcium chloride. You will of course, need to use the ionic charges to write the correct formula. Calcium chloride is a salt, and the formula shows a...
