Kcal=1000 cal
Min=60 sec
0.74 *1000= 740cal/min
740 cal/min /60= 12.333 cal/s
One Nitrogen and three iodine's react to form two nitrogen triiodides.
But with (added) speed
It can't be double the speed because 2x0=0
I think the correct answer from the choices listed above is option C. The can <span>from the cupboard will lose carbon dioxide more quickly because it is warmer and gases are less soluble in warmer temperatures. </span> Solubility of gases is a strong function of temperature and as well as pressure.
Total mass = 100 + 6.5 = 106.5 g
Specific heat of water = 4.18 Joules/gram °C
Q = mCpΔT
Q = 106.5 x 4.18 x (37.8 - 21.6)
Q = 7177 Joules
Moles of NaOH:
6.5 / (23 + 16 + 1)
= 0.1625
Enthalpy of reaction: 7177/0.1625
= 441.7 kJ/mol NaOH
