S2O2 because the molecular formula of SO is just SO because they are both diatomic elements, but the empirical formula is just the but mot simplified, or S2O2.
Answer:
The catalyzed reaction will take 1,41 s
Explanation:
The rate constant for a reaction is:
Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:
Replacing:
That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:
4,50x10⁻⁸ years×

=<em> 1,41 s</em>

U-238 has 92 protons, 146 neutrons, and 92 electrons.
Rn-222 has 86 protons, 136 neutrons, and 86 electrons.
U-238 is Uranium 238 and Rn-222 is Radon 222.
