Is CaCO3 solid or aqueous? Solubility: If a chemical substance dissolves in water, it is soluble or aqueous. If it does not dissolve in water, it is insoluble or a solid. Aqueous is represented with (aq) in a chemical formula and solid is represented with (s). Answer and Explanation:...
Question: Is liquid to gas endothermic or exothermic? Changes in Phase: There are two types of reactions that involve the transfer of energy between a system and its surroundings, endothermic and exothermic reactions. Endothermic reactions are those that require energy to be absorbed, and exothermic...
Aqueous hydrobromic acid (HBr) reacts with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide (NaBr) and liquid water (H2O). What is the theoretical yield of sodium bromide formed from the reaction of 34.8g of hydrobromic acid and 33.2g of so In acid-base...
Metallic surfaces can be sprayed or dipped with aqueous dispersions of PTFE particles to form a permanent coating. Dispersions of PTFE can also be spun into fibres. It appears to me that if one wants to make progress in mathematics, one should study the masters and not the pupils. - Niels ...
(e.g. HBr, especially concentrated aqueous HBr), or a nucleophile such as mercaptoacetic acid di-lithium salt, potassium hydroxide, potassium tert-butoxide, or sodium or potassium thiophenolate, or a reducing agent such as LiAlH4), at or above room temperature (e.g. at reflux) with or ...
Zinc + copper sulfate is an example of a single replacement reaction. Zinc is higher than copper on the electromotive series, so will react to displace the copper from copper sulfate. This reaction takes place in an aqueous solution. The balanced chemical reaction is...
(The aqueous chloride is not involved in any reaction there). Nothing is as simple and accurately known in real life as the books will tell you. OchoaAnswered Jan 10 2022 I created this diagram usingTeresa Gemellaro’sanswer, so thanks to her. I really needed more than a balanced equation...
Is this true or false and can you explain why? True or false? Electrolytic reactions and voltaic reactions are both spontaneous reactions. In determining the equilibrium constant for a reaction, reactants or products in solid or aqueous form are not included in the expressi...
True or false? Copper(II) hydroxide is soluble in water. True or false? In the electrolysis of aqueous Na2SO4, sulfate ion is oxidized at the anode. True or false? If a reactant is in the solid state, a (g) is placed as a subscript after the che...
Which solution forms a precipitate when mixed with a solution of aqueous Na_2CO_3? For the equilibrium, SbCl_3 (s) + H_2O to SbOCl(s) + 2HCl (aq). A.) What reagent would you add to the system to dissolve SbOCl? B.) What reagent would you add to precipitate SbOCl? Predict the...
