The specific heat of aluminum is 0.897 j/g•°c. which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°c to 29°c?
a. q = 0.75 g x 0.385 j/g•°c x 29°c
b. q = 0.75 g x 0.385 j/g•°c x 22°c
c. q = 0.75 g x 0.897 j/g•°c x 22°c
d. q = 0.75 g x 0.897 j/g•°c x 29°c

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
