C. Another radioisotope of americium exists which has an atomic mass of 242.
Americium-242 has a half-life of 16 hours.
i.
A sample of americium-242 has a mass of 8 g.
Calculate the mass, in grams, of americium-242 that would be left after 48
hours.
Show your working clearly.

Write the overall equation for the reaction for lithium battery

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
