The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
When looking at a titration curve: Volume of NaOH at the equivalence point: 18.9 mL Volume of NaOH at half the equivalence point: 9.45 mL Calculate the number of moles of NaOH at the equivalence point. Provide general steps (and relevant equations) on...
Once the rates given in Eq. (1) for all the Tb radionuclides of interest are determined, the time evolution of the number of produced radionuclides, and the evolution of the activities during and after an irradiation can be calculated from the Bateman equations. The time dependence of the num...
Studying physics requires a strong background in mathematics, and students should expect to complete coursework in calculus and differential equations, for instance. Students may be able to take a placement test to determine where to start in their program. Some schools offer degrees in applied ...

and it’snever too early to start yours. It can also help you stretch your résumé if you lack job experience. Instead of thinking about your required chemistry class during sophomore year as learning about stoichiometry and balancing chemical equations, think about it as what you r...
In an attempt to be more like the academically respected "hard sciences" of physics and chemistry, economics became math-intensive. Variable uncertainty, however, was a major problem; economics could not isolate controlled and independent variables for math equations. There was also a problem with ...
