Which mento will explode first?
The three reasons that scientists found Rutherfor's nuclear atomic model to be fundamentally incomplete are as follows:
Number 1) according to Rutherford, the electrons revolve in completely
circular orbits. However, if this was true the charged electron would
simply fall into the nucleus after losing energy.
Number 2)
According to Rutherford's model, the nucleus itself only consisted of
protons. However, as we now know due to research in quantum mechanics,
if this was true this would make the atom unstable due to the cycle of
attraction and repulsion.
Number 3) The neutrons which have also
been discovered since to be an important part of the atom, are not
mentioned at all in Rutherford's model.
Answer:
it forms :
1. Gold ( Au )
2. Zinc nitrate ( Zn(NO3)2 )
Explanation:
When a chunk of zinc is added to a solution of gold (III) nitrate to extract the gold. The reaction forms Gold and Zinc nitrate .
it's a single displacement reaction,
here's the balanced equation for above reaction :
3 Zn + 2 Au(NO3)3 =》3 Zn(NO3)2 + 2 Au
There is no graph but the reason people who have aids cant fight it off is because it is an immune disease it quickly weakens the immune system and makes a persons body too weak to fight anything off.
True.
This is a combination of an anion and a cation to form a neutral compound.
