Which of the following substances (with specific heat capacity provided) would show the greatest temperature change upon absorbing 100.0j of heat? a. 10.0 g fe, c fe=0.449j/g°cb. 10.0 g ethanol, c ethanol =2.42j/g°cc. 10.0 g h2o, ch2o = 4.18j/g°cd. 10.0 g ag, c ag =0.235j/g°ce. 10.0 g pb c pb = 0.128j/g°c

Pb would show the greatest temperature change upon absorbing 100.0 J of heat , which is : 78.125  ° C

The law of conservation of energy can be applied to heat changes, i.e. the heat received / absorbed is the same as the heat released

Q in = Q out

Heat can be calculated using the formula:

Q = heat, J

m = mass, g

c = specific heat, joules / g ° C

∆T = temperature difference, ° C / K

Because temperature change is inversely proportional to the value of c (heat capacity) and because the mass of an element / compound is equal = 10 g,and the heat absorbed also the same, then the greatest temperature change upon absorbing 100.0J of heat is the one with the smallest heat capacity (c), namely: Pb with C Pb = 0.128J / g ° C

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
