Building a space station in orbit is a safety measure. If a rocket fails to bring up the entire space station in one piece it would be extremely expensive to build a new one. Bringing it up in multiple places ensures less money would be lost if the rocket fails.
The basic difference between chlorine and blench is that a natural element, while bleach is a solution of many elements.
Hope this help..
T=2T
m=10 g
m=m₀2^(-t/T)
m₀=m/{2^(-2T/T)=m/2⁻²
m₀=10/2⁻²=40 g
40 grams
Answer:
Two objects are in thermal equilibrium if they are in close contact that allows either to gain energy from the other.
Answer:
No empty orbitals but five unpaired electrons.
Explanation:
Hello there!
In this case, when going over the empty orbitals in valence energy levels, it is required to develop the electron configuration in order to appropriately describe the element. In such a way, for the element whose atomic number is 25 because it equals the number of electrons, we obtain:

It means that the d orbital is half filled which means that it does not have any empty orbital wherein two electrons are contained per orbital. Moreover, we can find 5 unpaired electrons according to:
↑ ↑ ↑ ↑ ↑
Which is the orbital notation.
Best regards!
