Two balloons are at the same temperature and pressure. one contains 14 g of nitrogen and the other contains 20.0 g of argon. pick the false statement from the following list.
(a) the density of the nitrogen sample is less than the density of the argon sample.
(b) the average speed of the nitrogen molecules is the same as the average speed of the argon molecules.
(c) the average kinetic energy of the nitrogen molecules is the same as the average kinetic energy of the argon molecules.
(d) the volume of the nitrogen container is the same as the volume of the argon container.
(e) the number of molecules in the nitrogen container is the same as the number of atoms in the argon container

Pls! plant cells and animal cells were observed under a microscope. the characteristics of two cells are listed below. cell p: does not capture sunlight cell q: has cytoplasm but no chloroplast which statement about the two cells is correct? cell q also has a cell wall. cell q also has large vacuole. cell p also has a large vacuole. cell p also has a cell membrane.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
