The pressure will continue to build up eventually causing a release of pressure or an explosion.
Answer: a
Explanation:
scientific notation is about how many places passed the decimial place you are moving. therefor in order to get 1,550,000,000 you would move the decimial from 1.55 over nine times to the right
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
A. Humidity
