Calcium iodide (chemical formula <span>CaI2</span>)
There is no way to know which reaction requires which catalyst. However, if you apply copper to a reaction where it does act as a catalyst, the rate of reaction will be much faster as it lowers the activation energy for successful collisions.
Answer : Half life and radioactive decay are inversely proportional to each other.
Explanation :
The mathematic relationship between the half-life and radioactive decay :
................(1)
where,
N = number of radioactive atoms at time, t
= number of radioactive atoms at the beginning when time is zero
e = Euler's constant = 2.17828
t = time
= decay rate
when 
then the number of radioactive decay become half of the initial decay atom i.e 
.
Now substituting these conditions in above equation (1), we get
By rearranging the terms, we get
Now taking natural log on both side,
By rearranging the terms, we get
This is the relationship between the half-life and radioactive decay.
Hence, from this we conclude that the Half life and radioactive decay are inversely proportional to each other. That means faster the decay, shorter the half-life.
A. radiation
Explanation:
The heat transfer mechanism that causes the surface of the earth to gain heat is by radiation.
Electromagnetic radiation is able to cause the heating of the surface by radiation.
Radiation is one of the methods of heat transfer the does not involve any particle.
The surface of the earth absorb some of the radiation and it causes them to warm up.
