Strong acids have 100% ionization, while weak acids ionize to a much lower extent (such that the molecular form is favored at equilibrium).Answer and Explanation: True. When a weak acid (HA) is placed in water, it reacts with water as follow...
When ammonia combines with water, it forms the aqueous salt ammonium hydroxide. Ammonium is a monovalent cation with formula NH4+. All ammonium salts are soluble in water. Answer and Explanation: Part (a) - Reaction The reaction of magnesium with gaseous ammonia produces...
When a pebble falls from space into the atmosphere, moving at tens of kilometers a second, it gets rid of a lot of energy. Like the energy from the sun's rays, this ionizes the molecules of the atmosphere. The meteor's 10—20km path is densely packed with ions. By the 1930s, ra...
Bromine does have a couple of drawbacks, though. While it lasts longer than chlorine, it also works more slowly, which means contaminants are in the water longer before they’re destroyed. It’s also unstabilized, which means if you use it in an uncovered, outdoor hot tub, it’ll burn...
Which compound produces a basic solution when dissolved in water? (a) NH_4Cl (b) NaF (c) KClO_4 (d) KCl (e) Ca(NO_3)_2. Consider the reaction of nitric acid, HNO_3, and acetic acid, CH_3COOH. Write a balanced chemical equation showing the proton transfer reaction that would ...
When a reaction needs energy to become spontaneous, sometimes they can get it trough heating, then, they have available enough energy of activation to start the reaction. Answer and Explanation:1 For the lithium nitrate: {eq}4LiNO_3 \rightarrow...
The meniscus on the surface of water in a test tube is the result of water's viscosity. In Craig tube microscale crystallization, it is fine to centrifuge the tube if you don't see any solid; the centrifuge will cause the crystals to form. True or false? True ...
As they give the maximum amount of hydroxyl group (OH−) then these compounds are termed as a base while which give hydrogen (H+) then, this compound termed acid. Answer and Explanation: 1. NaOClO2: When this compound is diss...
Fluorine 18 (18F) is produced in a cyclotron by bombarding oxygen 18–enriched water with protons and it represents the key principle on which the functioning of the PET scan is based and is administered by intravenous injection [36]. 18F-FDG was developed in the 1970s in the first PET ...
