Answer is: <span>to decrease activation energy.
Manganese(IV) oxide is catalyst in this reaction.
</span>Catalysis <span>is the increase in the </span>rate<span> of a </span>chemical reaction<span> due to the participation of an additional substance called a </span>catalyst. R<span>eactions occur faster with a catalyst because they require less </span>activation energy<span>.</span>
The question is asking the ratio of H to S in H2SO4.
In the following molecular formula, there are 2 hydrogen and 1 sulfur.
This means that the ratio is 2:1.
Molar mass Argon ( Ar ) = 39.95 g/mol
39.95 g ---------------- 6.02 x 10²³ atoms
0.377 g ---------------- ( atoms Ar )
( atoms Ar ) = 0.377 x ( 6.02 x 10²³ ) / 39.95
( atoms Ar ) = 2.26954 x 10²³ / 39.95
= 5.68 x 10²¹ atoms Ar

Answer:
67.824
Explanation: You want to use the combined gas law equation (P1*V1)/(n1*T1)=(P2*V2)/(n2*T2). So first cross out what remains constant, so volume(V) and I assume moles (since it was not mentioned as a change). Then you can solve algebraically for the answer!
