Uno de los metales que se oxida fácilmente es el hierro (Fe), se nota cuando se forma una capa (óxido) de color rojizo llamado herrumbre. Determina la cantidad de Oxido férrico que se obtiene si se oxidan 10 g de hierro. Considera que la reacción química presente es: Fe + O2 + H2O → Fe2O3 + H2O

The pressure inside a hydrogen-filled container was 2.10 atm at 21 ? c. what would the pressure be if the container was heated to 92 ? c ?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
