Question

In the reaction, CH4 + 2O2 arrow CO2 + 2H2O, 890 kilojoules of heat are released. Using Einstein's equation, calculate the mass amount to which this energy equates. (1 J = 1 kg m2 s-2) and the speed of light = 3.0 x 108 m/sec

9.9 x 1012 kg

9.9 x 10-12 kg

9.9 x 10-14 kg

1.1 x 10-6 kg

Answer 2

Oh already here lol

Answer 3

9.9 x 10-12 kg

Answer 4

E=mc^2
E=890×10^3 joules
C=3×10^8 m/s

Answer 5

M=?

Answer 6

m = e/c^2
