Is barium metal or nonmetal? What is ferric chloride? What is the empirical formula for copper oxide? What is the name for CuO? Is galena a sulfide mineral? Is silver flammable? How do alkaline earth metals react with water? What gas is released in the process of smelting? Is metallic ...
How many electrons are in the highest occupied energy level of barium? Why doesn't ethane and water react? Most companies that use any version of exponential smoothing use fairly small smoothing constants such as 0.1 or 0.2. Explain why they don't tend to use larg...
Alka-Seltzer contains the base sodium hydrogen carbonate, NaHCO3, which reacts with hydrochloric acid in the stomach to yield sodium chloride, carbon dioxide, and water. What volume of CO2 gas at 104.5kPa and 311K would be formed when 10.0mL of 1M HCl is Describe how to prepare a...
The base of silver is weak, whereas chlorine acid is strong. When the weak base reacts with a strong acid, it formsacidic salt. It means the salt that produces acidic ph, currently (ammonia), becomes a base when dissolved in water. Thus, chlorine from AgCl reacts with NH₃ to produc...
The neutrons can go on to react with more uranium-235 atoms (5) in a hugely energetic chain reaction. Other fission reactors are possible when a neutron hits uranium-235, producing either two or four spare neutrons. That's why (confusingly) you'll sometimes read in books that uranium-235...
Atomic Structure. Key 11 Na Sodium Atomic Number Element symbol Element name Average atomic mass* ELECTRONS!!! Parts of an atom. Electrons Negative charge Located outside the nucleus in an electron cloud They are organized into shells Move very quickly. ...
Approximately one mol of vinyl haloformate reacts with one equivalent weight of the salt in such reaction. However, excesses of either reactant does not appear to be objectionable. The reaction is generally conducted by permitting a mixture of the carboxylic acid salt and the vinyl haloformate...
In an experiment, ferric ions were reacted with thiocyanate. How might the results differ if ferrous ions were used instead? Explain the differences in conductivity of NaCl, CaCl_2, and AlCl_3. Describe chemical tests that could distinguish between acetic acid and acetaldehyde....
Determine the value of the solubility product constant for this strong electrolyte. Lead(II) bromide does not react with water. A. 5.Is a potassium nitrate solution expected to be a strong electrolyte? Explain.Give the ion when the following strong e...
What do the members of the noble gas family have in common? a. They are mostly chemically inert. b. They almost never react with other elements. c. They have filled outer electron configurations. d. All of the above. How does one isotope differ from ...
