True, different reactions require different catalysts. Hence, option 1 is correct.
<h3>What are catalysts?</h3>
A catalyst is a substance that speeds up a chemical reaction or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.
Though a catalyst is supposed to remain unaltered at the end of the reaction, it does take part in the reaction by providing active centres for the reaction to take place.
By helping to form a suitable activated complex in the course of the reaction, the catalyst increases the rate of formation of the product, as well as its yield.
Therefore, a catalyst has to be reactant-specific to form the favourable activated complex or intermediate.
Hence, option 1 is correct.

Non polar covalent bond. The Cl's electronegativity is the same since it's the same atom. Therefore, they will be nonpolar
Heat & pressure. hope this helps
Answer:
I believe Si12H26+02 is the coefficient I might be wrong, Sorry if I am.
Answer: 20 mg Te-99 remains after 12 hours.
Explanation: N(t) = N(0)*(1/2)^(t/t1/2)
N(t) = (80 mg)*(0.5)^(12/6)
N(t) = 20 mg remains after 12 hours
