What is a nonelectrolyte? Nonelectrolytes: Chemicals that dissociate in water break into ions that form electrolytes. Electrolytes are classified as strong, weak, or non-electrolytes based on the amount of chemical that dissociates in water. Answer and Explanation: A nonelectrolyte is a chemical...
This article presents a personal answer to the question “What is chemistry?”, set out in terms of six propositions. These cover “pureR
This symbol could represent which of the following elements? a) P b) Ca c) Si d) Na e) Ne f) S g) Cl h) Al An atom of an element has the following ground-state configuration: Ar 3d10 4s2 4p6. If the element is in Group VIA, what is the symbol of the element?
Originally, a mole was the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's number, which is roughly 6.02x1023. A mole of carbon atoms is 6.02x1023carbon atoms. A mole of chemistry teachers is 6.02x1023...
What is Chemical Synthesis? Chemical synthesis describes the physico-chemical transformation that occurs when two or more simpler molecules combine in a controlled fashion to produce a more complex chemical product. Often chemical synthesis is far more complex than A+B = C, and mixtures can occur ...

【题目】What's the water Jike?The students are having their chemistry class. Sar a is talking to the children about the water. After that, she asks a question, “What's the water like?" She waits for a few minutes, but no one answers. Then she asks again,"Why don't you answer ...
In multiplexing, you can reduce the amount of sample required for a qPCR reaction by measuring the expression of more than one gene in a reaction. The process is as sensitive and accurate as single-gene amplification (or singleplexing), but more technically complex...
thus becoming the first university in the world to do so—the iMOOC model” [5], which will be discussed further in this chapter. The iMOOC model: “the model is patented and is composed of a set of standardized pedagogical practices extended to the whole institution, each one dedicated to...
