Answer:
I think it is 183 sorry if I am incorrect
Explanation:
But the systolic pressure is the top number so that makes sense
The melting point would decrease
The answer is (2). You can think about this question in terms of the Bohr's model of the atom or in terms of quantum chemistry. In the Bohr model, electrons exist in discrete "shells," each respresenting a fixed spherical distance from the nucleus in which electrons of certain energy levels orbit the nucleus. The larger the shell (the greater the "orbit" radius), the greater the energy of the "orbiting" electron (I use quotations because electrons don't actually orbit the nucleus in the traditional sense, as you may know). Thus, according to the Bohr model, a third shell electron should be farther from the nucleus and have greater energy than an electron in the first shell.
The quantum model is differs drastically from the Bohr model in many ways, but the essence is the same. A larger principal quantum number indicates 1) greater overall energy and 2) a probability distribution spread a bit more outward.
Answer:
electron revolving in a shell is associated with a definite amount of energy. The energy changes when it jumps to another shell that is so say when it goes from one level of energy level to another. Thus shell also gives the energy of a electron besides its location and are therefore called energy levels.
Mass=density·volume. The density us 1.03g/mL and the volume is 85.32mL. So you will multiply 1.03g/mL by 85.32mL which will give you 87.8796g. Do you need it in the correct amount of significant figures?
