4.68088652 Be sure to answer all parts. The ΔG o for the reaction H2(g) + I2(g) ⇌ 2HI(g) is 2.60 kJ/mol at 25°C. In one experiment, the initial pressures are PH2 = 3.53 atm PI2 = 0.017 atm PHI = 0.53 atm Calculate ΔG for the reaction and predict the direction of the net reaction.

Answer//the law of conservation of mass.;

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.

For each molecule of glucose processed during glycolysis, the net yield is two molecules of pyruvate, two molecules of nadh and two molecules of atp. glycolysis is the process in which sugar or glucose is broken down to simpler compounds to produce energy to the cells in the form of atp. it is an essential metabolic pathway which involves the oxidative breakdown of one glucose into two pyruvate with the capture of some energy as atp and nadh. in the process two atp molecules are utilized during the process, while 4 atp molecules and 2 nadh molecules are produced. since two atp molecules are utilized during the process, thus the net gain of 2 atp and 2 nadh molecules
