The answer is C. burning the stick. This is because burning the stick will change the chemical properties of the wood, and it will not be wood anymore, it will be ash and the rest will be heart or gas.
(159 g Ca/1) x (1 mol Ca/40.07 g Ca) x (6.02*10^23 atoms Ca/1 mol Ca)
= 2.39*10^24 atoms Ca.
Answer:
The conjugated base of ammonium ion 
is 
Explanation:
A conjugate base is obtained by addition of proton 
. In order to get the conjugate base of , we need to add a proton to ammonium ion. We will get after addition of proton to ammonium ion.
Hence, the conjugate base of is
Answer:
When the number of electrons does not equal the number of protons, the atom is ionized and then they are no longer atoms, they are known as ion(s).
