Biology is the most bullshit science, this includes medical science. They tend to make up more data than any other group of scientists because they are the least empirical.
Engineers, chemist, and physicist can't get away with this kind of shit because all of their work is backed by empirical evidence. There are a lot less redaction and falsely published studies in other fields of science when compared to biology. That is because they do real science, and not just look at shit under a microscope, or count water buffalo. Biology should be considered a soft science. Furthermore shit is always changing in biology which is just proof that biologist don't know what the fuck they are doing. There are also very few laws in biology that weren't taken from physics, chemistry, or engineering. At best biology is somewhere in between a hard/physical science and a social/soft/bullshit science.

Calculate the enthalpy change, in kJ, for the reaction: C2H4 +H2 -> C2H6, from the following data.
C2H4 + 3 O2 -> 2 CO2 + 2 H2O H = -1411 kJ
C2H6 + 7/2 O2 -> 2 CO2 + 3 H2O H= -1560. kJ
H2 +1/2 O2 -> -> H2O H= -285.8 kJ
Calculate the enthalpy change, in kJ, for the reaction: Ca + C + 3/2 O2 -> CaCO3, from the following data.
Ca + 2 C -> CaC2 H= -62.8kJ
CO2 -> C + O2 H= 394 kJ
CaCO3 + CO2 -> CaC2 + 5/2 O2 H= 1538 kJ
Calculate the enthalpy change, in kJ, for the reaction: 2 H2 + 2 C + O2 -> C2H5OH, from the following data.
C2H5OH + 2 O2 -> 2 CO2 + 2 H2O H= -875 kJ
C + O2 -> CO2 H= -394.51 kJ
H2 + 1/2 O2 -> H2O H= -285 kJ
Calculate the enthalpy change, in kJ, for the reaction: CS2(l) + 2 H2O(l) -> 2 H2S(g) + CO2(g), from the following data.
H2S(g) + 3/2 O2(g) -> H2O(l) + SO2(g) H = -563kJ
CS2(l) + 3 O2(g) -> CO2(g) + 2 SO2(g) H = -1075kJ

Been hitting this bitch with trial and error for a while now, and I'm inclined to say the answer is "no" based on just that.
However, I'm sure there's an actually efficient mathematical way to approach this, but I just don't know it yet.
Can anyone help?
