The specific heat of lead is 0.129 J/gC. Find the amount of heat released when 2.4 moles of lead are cooled from 37.2C to 22.5
labwork [276]

Answer:

-943J or 943J released

Explanation:

m=2.4 mol x 207.g/ mol=497.3g

c=.129 J/gC

T= T f-Ti=(22.5-37.2)=-14.7C

Q=?

Q=(49.3g)(.129 J/g C) (-14.7 C)

= -943 J or 943 J released

Delicious77 [7]

Answer:

The response can be defined as follows:

Explanation:

ATP is a hydrolysis energy-saving money of the cell. It is used to support the cell's endothermic processes.

ATP\ +\ H_{2}O\ \rightleftharpoons \ ADP\ +\ P_{i}\\\\Q\ = \ \frac{[ADP][P_{i}]}{[ATP][H_{2}O]}\\\\ADP= 0.250 \ M\\\\P_i = 0.010 \ M\\\\ATP = 0.150 \ M\\\\H_2O = 55.55 \ M\\\\\Delta G \ =\ \Delta G^{o}\ +\ 2.303\ RT\ \log\ Q\\\\R = 8.314 \frac{J}{mol\ K}\\\\T = 298\  K\\\\
