Answer:
Nucleus
Explanation:
The atom is mainly formed by three particles: Protons, neutrons and electrons. While the first two are inside of the nucleus, the latter orbit around it. Also, protons and neutrons have a relative mass of 1, compared to the electrons which mass is only 0.0005.
Answer:
Explanation:
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
partial pressure of water vapour = 18.7 mm of Hg
760 mm of Hg = 1 atm
18.7 mm of Hg = 18.7 / 760 atm
= .0246 atm
Total pressure = partial pressure of nitrogen + partial pressure of water vapour
Putting in the values in atm
1.72 atm = partial pressure of nitrogen + .0246 atm
partial pressure of nitrogen = 1.72 atm - .0246 atm
= 1.6954 atm
= 1.70 atm
partial pressure of nitrogen = 1.70 atm .

The question is incomplete, the complete question is;
Arrange the isotopes of chlorine and sulfur in order of decreasing number of neutrons. Rank the isotopes from most to fewest neutrons. To rank items as equivalent S-33,S-36,S-34,Cl-35,S-32,Cl-37
The isotopes of sulphur arranged in order of decreasing number of neutrons is; S-36, S-34, S-33, S-32. The isotopes of chlorine arranged in order of decreasing number of neutrons is; Cl-37, Cl-35.
Isotopes are atoms of the same element having different mass numbers but the same atomic number.
Isotopes differ in their number of neutrons. The number of neutrons is obtained by subtracting the atomic number of an isotope from its mass number.
The number of neutrons in the isotopes of sulphur are;
S-36 (20 neutrons)
S-34 (18 neutrons)
S-33 (17 neutrons)
S-32 (16 neutrons)
The number of neutrons in the isotopes of chlorine are;
Cl-37 (20 neutrons)
Cl-35 (18 neutrons)

Answer:
B= magnetic field strength
Explanation:
use formula E = Blv
l=length
v=speed
this works if field &wire carrying current is perpendicular only
make sure you get your units right
