What do brackets mean in organic chemistry?Organic Chemistry:Organic chemistry focuses on the element carbon, including molecules that contain carbon and their reactions. Organic chemistry is important because carbon makes up many molecules in living things....
Think back to math: there’s a difference between 4 + 2 * 3 and (4+2)*3.In organic chemistry, we use brackets in exactly the same way. Consider a case where you have four CH3groups attached to a carbon. You wouldn’t write it CH3CH3CH3CH3C ; writing it like that implies a cha...
Briefly describe what the Bragg equation relates. When do you use the root means square equation? In chemistry, what does Keq mean? Explain the significance of the equation n = c V in chemistry. Why do we define (1/X)(d^2/dx^2)X as (-2mE_x/h^2) and not simply as E?
So, mathematically, pH is the negative log to base 10 of the proton concentration. In chemistry, the concentration of any species is denoted by writing it in square brackets. For example, [X] means “the concentration of X.” Given the above definition of pH, the fact that a proton is...
Forty participants were excluded because they completed the survey too quickly (less than 4 min, Mdn = 16.63), which made it implausible that they responded thoughtfully. The final sample size was N = 1286. The mean age of the participants was M = 23.62 (SD = 4.47). Among the ...
Nor does it mean that we should suppress emotion. Emotional stability means we continue to experience and express healthy emotions relevant to our ongoing circumstances and do not become 'unstable' by slipping into sentiment. We learn this in the same way the unconscious learns everything -simp...
The brackets [ ] is generally used to show concentration means what is the concentration of hydrogen ion in the solution say water or soil solution or blood or any other liquid which is aqueous (neither solid nor gas completely devoid of water or moisture) ...
The plots have a mean annual temperature between 7.4 and 9.6 °C and a mean annual precipitation total of 700 to 1385 mm. They are located at altitudes ranging from 172 to 816 m a.s.l. The acid topsoil (0-5 cm) had pH (KCl) values ranging from 2.9 to 4.1 and in humus from ...
“All of the listed references were retracted 1 or 2 years after our publication. I don’t understand; what do you mean by listing the retracted paper after our publication? It seems to us that you want to create doubt in our publication, and you are not being fair enough.“ ...
In geometry, what is the definition of the hypotenuse? What does the upside down 'v' mean in math? Provide an example. How do you put tan5=b/2 in a calculator? What is a complementary event in math? What is a linear expression? How do you know when to place brackets around numbers...
