The half life a a certain radioactive material is 4 years. After 24 years, how much of a 75g sample will remain? Could I get a step by step way of solving?

Tolerance to high levels of salinity

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
