Argon-39 has a half-life of 269 years. How long will it take for 52.5 g of a 60.0 g sample to decay to its daughter isotope?

Answers

Answer 1

Answer:

The years that will take or 52.5 g of a 60.0 g sample to decay to its daughter isotope is 807 years.

What is half-life?

Half-life is the time required to decay or undergo half the process of any element.

Given the sample is 60.0 g in which 52.5 g sample has to be decay

so, 60 - 52.5 = 7.5 g

It can be seen that it goes three half life

60 >30 >15 >7.5

Now, the half life is 269

269 × 3 = 807 years.

Thus, the years taken are 807 years.

Answer 2

Answer: For 60.0 g sample, if it remains 60-52.5=7.5 g, it will go through 60->30->15->7.5, 3 half-life. So the time being taken is 269*3=807 years.

For any given reaction, which of the following will speed up the reaction rate? a)increase the temperature
b)add a catalyst
c)increase the surface area
d)All of the choices are correct.
e)None of the choices are correct.

Answers

All of the choices are correct. Catalysts increase reaction rate by lowering the activation energy of a reaction. When you increase both the temperature and surface area you are just increasing the number of collisions which also increases the reaction rate since the reaction happens when molecules or atoms collide in the correct orientation and with enough energy and you are increasing the number of times that happens in a given time period.
