Which statement explains how the Sun influences movement in the Earth's atmosphere? The Sun heats the Earth evenly; this heating pattern then causes conduction in the atmosphere.

The Sun heats the Earth unevenly; this heating pattern then causes conduction in the atmosphere.

The Sun heats the Earth evenly; this heating pattern then causes convection currents in the atmosphere.

Based on the equation and the information in the table, what is the enthalpy of the reaction?

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.

The continuous release of nuclear energy caused when one fission reaction triggered more nuclear reactions is a
