1) El CO2 que los astronautas exhalan se extrae de la atmósfera de la nave espacial por reacción con KOH según la reacción: CO2 (g) + 2 KOH (l) → K2CO3 (s) + H2O (l) a) Cúantos gramos de CO2 se pueden extraer con 500 g de KOH ? b) Cuántos gramos de agua se producen? 2) Cuando se hacen reaccionar hidrógeno y nitrógeno se produce amoniaco, un fertilizante benéfico para las plantas. ¿Cuántos moles de hidrógeno se requieren para que reaccionen con 12.75 moles de nitrógeno? La reacción es la siguiente: N2 + 3 H2 → 2NH3 3) El propano (C3H8) es usado como combustible en los hogares, reacciona con el oxigeno para producir dióxido de carbono (CO2) y agua (H2O) mediante la siguiente reacción: C3H8 + 5 O2 → 3 CO2 + 4 H2O a) Si se queman 2 Litros de propano (C3H8) calcula los litros de CO2 que se emiten a la atmósfera.

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.
