Answer is: 1160 J of heat Is required to increase the temperature.
m(Fe) = 100 g.
∆T = 40,2 - 15 = 25,2°C.
C(Fe) = 0,46 J/g•°C.
Q = m(Fe) • C • ∆T.
Q = 100 g • 0,46 J/g•°C • 25,2°C
Q = 1160 J.
C - specific heat.
Answer:
1
only 4 is the significant figure
we take tailing zeroes as significant figures only in case of decimals
Simple sugar! Good luck! :)
True because hydrogen ions combines with h2o to make hydronium ion, so in a sense h2o is acting like a base.
