Why do atoms have an overall neutral charge? What would happen if OH-ions were added to a very basic solution? What is the electron configuration of the calcium ion? What is an example of the common-ion effect? Which type of ion channel opens ...
Thomson also knew that atoms are electrically neutral, meaning that they have no overall charge. He reasoned that there must be some positive charge in atoms that cancels out the negative charge of the electrons. He also followed the work of William Thomson (Lord Kelvin), who had proposed a ...
So protons and electrons are a bit like the two different ends of a battery: they have equal and opposite electric charges. Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative ...
formal charges of each atom g. bond order How many of the the following molecules are of (S) configuration? Non-bonded electrons have been omitted. a. 0 b. 1 c. 2 d. 3 What is the Lewis structure of carbon monoxide? Why is fluo...
(lithium atoms that have lost an electron to become positively charged) from one part of the battery to another. When you unplug the power and use your laptop or phone, the battery switches into reverse: the ions move the opposite way and the battery gradually loses its charge. Read more ...
Cold-adapted enzymes from psychrophilic species show the general characteristics of being more heat labile, and having a different balance between enthalpic and entropic contributions to free energy barrier of the catalyzed reaction compared to mesophili
for the negative charge at both of its carboxylate locations during the reaction, the reorganization energy can be reduced significantly. It appears that the reason why this major catalytic effect has not been revealed earlier for glucosidases, is that no comparisons to uncatalyzed water reactions ...
Answer to: Indicate whether the following statement is true or false. If the statement is false, explain why. Stereoisomers are one type of...
Why don't electrons in atoms repel? Define Boyle's law and Charles's law. Explain why metals conduct electricity. (a) Explain Millikan's oil drop experiment. (b) How it led to the measurement of the electron's charge? (c) Why is the magnitude of the charge of the electron so import...
For example, if you buy a smartphone, you don't simply do things on your phone that you used to do on your PC: you spend more time online overall, using apps and services that you previously wouldn't have used at all. Cloud computing made mobile devices feasible, so people bought ...
