Hello there!
They believe that the chemical evolution occurred around 3.5 billion years ago.
They also believe that the chemical occurred in the ocean
As always, it is my pleasure to help students like you!

Answer:
2S02 + O2 ---> 2SO3

HCl:
<span>
m=48,2g
M=36,5g/mol
n = m/M = 48,2g / 36,5g/mol = 1,32mol
1mol : 4mol
MnO</span>₂ + 4HCl ⇒ MnCl₂ + Cl₂ + 2H₂O
0,86mol : 1,32mol
limiting reagent
0,33 will react
HCl is limiting reagent.
The balanced nuclear equation for the β emission of the following isotopes is seen below:

<h3>
What is Beta emission?</h3>
This is also known as beta decay in which a beta ray is emitted from an atomic nucleus.
The element formed during the beta emission of strontium is referred to as Yttrium.
