Answer:
Answer C
Explanation:
Heat is used to turn the solid ice into liquid water
B) 6
one above one below and 2 on the left and right sides
The heat released by the substance in the calorimeter is equal to the heat absorbed by water which results to the decrease and increase in temperature, respectively.
We use m Cp ΔT to balance the heat involved
(m Cp ΔT) subs in calorimeter = <span>(m Cp ΔT) water
</span>125 g * Cp * (97.0-23.5 ) C = 250 g *(4.18 J/C g)* (23.5-20)
Cp = 0.398 J/Cg
Answer is B
I'm guessing D or C, remember that the noble gases cannot combine
