Choose all of the chemical reactions which correctly show that chemical reactions must obey the law of conservation of matter. ch4 + 2o2 → co2 + h2o h2 + o2 → h2o c6h12o6 + 6o2 → 6co2 + 6h2o 2co + o2 → 2co2 4p + o2 p4o10

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.
