2. The reaction of zinc with nitric acid was carried out in a calorimeter. This reaction caused the temperature
snow_lady [41]

We want to solve Q = mcΔT for the liquid water; its change in temperature will tell us the amount of thermal energy that flowed out of the reaction. The specific heat, c, of water is 4.184 J/g °C.

Q = (72.0 g)(4.184 J/g °C)(100 °C - 25 °C) = 22593.6 J

Q ≈ 2.26 × 10⁴ J or 22.6 kJ (three significant figures).

Convert the boiling point of cyclopropane at standard pressure to kelvins
Olenka [21]
Celsius to Kelvin conversion formula

<span>The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:</span>

T(K) <span>= T(°C) + 273.15</span>

 

So to convert the boiling point of cyclopropane from degrees Celsius to kelvin:

T(K) <span>= T(°C) + 273.15</span>

T(K) <span>= -33 + 273.15</span>

T(K) <span>= 240.15 K</span>

<span> </span>
