Answer:
The correct answer is option b, that is, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
Explanation:
The carbon-14 atoms, which are created by the cosmic rays associates with oxygen to produce carbon dioxide that plants captivate naturally and comprise it into plant fibers by the process of photosynthesis. Afterward, the plants are consumed by animals and human beings, thus, they take in carbon-14 as well.
The ratio of usual carbon-12 to carbon-14 in the air and in all the living species at a particular period is almost the same. These radioactive isotopes react in a similar manner as stable isotopes in the chemical reactions in the body.
I think the answer would be b because your throat is reacting to the cough?
Answer:
2
Explanation:
It is going through the air and is moving so that means that it has kinetic energy. But it is also going to go the down, which gives it potential energy.
mass of Cl₂ = 8.61 grams
Explanation:
We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.
number of moles = volume / 22.4 (L / mole)
number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Cl₂ = 0.123 × 71 = 8.61 grams
