1.75 moles ChCl3 x (6.02 x 10 ^-23) / 1 mole = 1.0535 x 10^-22 atoms.
hope this was helpful :)
No, the added heat melts the ice, but the result is water at the same temperature. Hence, option B is correct.
<h3>What is temperature?</h3>
The degree of hotness or coldness is measured on a definite scale.
Temperature doesn't change as heat is added during a phase change; for example, when the ice melts.
During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.
Thus, No, the added heat melts the ice, but the result is water at the same temperature.

I think the answer is C. 02
<span>mg = 2.42 g
Tg = 72.2 deg.C
mw = 15.8 g
Tw = 24.5
Tf = 27 deg. C
Cw = 4.18 J/g. deg. C
Energy balance for insulated system,
ΔE = 0
ΔUw + ΔUg = 0
ΔUw = - ΔUg
Qin = Qout
mg*cg*ΔTg = mw*cw*ΔTw
2.42*cg*(72.2 - 27) = 15.8*4.18*(27 - 24.5)
cg = 1.5095 J/g. deg.C or 1.5095 J/g.K</span><span>
