Answer:
Explanation:
CH4 + 2O2 --> CO2 + 2H2O
1mol generates 2 moles of H2O
Therefore 6 Moles produce 12 moles of H2O
Answer:
C) philosophical and intuitive speculation
Explanation:
Hi
Leucippus and Democritus proposed the concept of an atom based on philosophical speculation as a way of explaining reality with the scarcity of data available at that time.
The ideas of Leucippus and Democritus were rejected at that time but later retaken by Dalton when proposing his atomic model.
Success with your homework.
Answer:
328.4KJ
Explanation:
Before we move on to calculate enthalpy change, we calculate the amount of heat Q
Q= mcΔT
m = density * volume = 250 * 1.25 = 312.5g
c = 3.74J/g.k
ΔT = 7.80 + 273.15K = 280.95K
Q= 312.5 * 3.74 * 280.95 = 328,360.312 J= 328.4KJ(1000J = 1KJ, so divide by 1000)
The enthalpy change in the reaction is same as amount of heat transferred = 328.4KJ
