It is a consequence of the rearrangement of a element or compound's atoms when a chemical bond is broken or formed. Chemical reactions are typically classified into 4 major groups, each of them depending either on the number of substances in the reactant and product side...
Difference between Compound and Mixture Difference Between Crystalline and Amorphous Solid Difference Between Effusion and Diffusion Difference Between Electronegativity and Electron Affinity Difference Between Electrophile and Nucleophile Difference Between Element And Compound Difference Between Element And Compound D...
The molar mass of CaSO4 is 136.14 g/mol. To determine the molar mass, add the atomic masses of all the atoms in a compound. So, for CaSO4, Ca: 1...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer yo...
When the box is turned or tapped, the objects inside tumble into an arbitrary grouping, and when the diffusing screen is illuminated, the sixfold or eightfold multiplication creates a striking symmetrical pattern. The number of combinations and patterns is effectively without limit. Some kaleidoscopes...
7). The more readily a compound autoxidized to form a reactive electrophile the greater was its ability to inhibit NF-κB. The relationship best fitted a hyperbolic curve, resulting in a straight line when the rate of autoxidation was plotted on a log scale. The non-linear relationship ...
(Holo Hafergold, Neuform, Germany) 20 g, and trace element solution 5 ml, which was com- posed of (per liter deionized water) CaCl2Â2H2O 3 g, iron(III) citrate 1 g, MnSO4Â1H2O 200 mg, ZnCl2 100 mg, CuSO4Â5H2O 25 mg, Na2B4O7Â 10H2O 20 mg, CoCl2Â6H2O 4 mg and...
A solute can be an element, a molecular compound, or an ionic compound. Answer and Explanation: A compound is a collection of two elements or more that are attracted to one another through forces called intramolecular forces. These attraction......
Is salt water classified as an element, a compound, a homogeneous mixture, or a heterogeneous mixture? Explain. 1. You are given a solid substance and assigned the following task: a. determine if the substance is pure b. if impure, find a suitable method ...
The starting reactant in a single displacement reaction is a pure element, such as solid zinc metal, as well as an aqueous compound. Aqueous implies that the compound is water-soluble. The reaction will result in products that include a different pure element as well as a new aq...
Would you expect ethylene glycol to have greater solubility in water or in hexane? Explain. A blue solid is changed into a white substance and a colorless gas. Was the blue solid an element or a compound? Explain your reasoning. Why is heptane in...
