For a 1st order reaction:
In(n/n0)= -k * (time difference)
so k= - In (n/n0)/ (t/t0)
n is concentration at time t and n0 is the concentration at an earlier time t0.
where k is constant.
The combustion of a substance forming or breaking bonds mixing two substances.

A=mass number (protons + neutrons)
Z=atomic number (protons)
N=number of neutrons.
A=Z+N
Data:
A=24
N=13
Therefore:
24=Z+13
Z=24-13=11
Answer: The atomic number of this atom is 11. (The element is sodium)
Answer:
Explanation:
Precipitation, evaporation, freezing and melting and condensation are all part of the hydrological cycle - a never-ending global process of water circulation from clouds to land, to the ocean, and back to the clouds.
