Answer:
hydrogen + oxgen = nitrogen
Answer:
Q = m.c. ΔT
Explanation:
When temperature is changed the heat evolved or absorbed are calculating by following formula.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
When temperature is decreased heat is evolved and negative sign is added into Q value.
When temperature is increased heat is absorbed by system and positive sign is added with Q value.
Answer:
37.5 moles of O2 needed
Explanation:
2 moles of C6H6 need 15 moles of O2
5/2 * 15 = 37.5 of O2 needed

q = mC∆T
q = (30.0g)(0.900J/goC)(50oC)
q = 1350 J
So, the right answer is 1350 J
