Physical and Biological SciencesA bomb calorimeter was calibrated by burning 1.013 g of benzoic acid(C7H6O2) (ΔUcomb = 3.221 × 103 kJ/mol). The temperature change in thecalorimeter during the calibration combustion was 5.19°C. A nutritional chemist then used the calibrated calorimeter to determine the energy con-tent of food. The chemist carefully dried a sample of food and placed 0.8996 g of the sample in the calorimeter with sufficient oxygen for thecombustion to go to completion. Combustion of the food sample causedthe temperature of the calorimeter to increase by 4.42°C.1.

What does the first law of thermodynamics state? Question 13 options: There is and always will be the exact same amount of energy in the universe. As temperature approaches absolute zero, the entropy approaches a constant minimum. Entropy of an isolated system tends to increase. If two systems are in equilibrium with a third, then they are in equilibrium with each other.
Polonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of P210o change into after it emits an alpha particle.
Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?
