A reaction occurs via the following sequence of elementary steps. What is the reaction intermediate?
Trava [24]

Answer:

C is the reaction intermediate.

Explanation:

A reaction intermediate is a molecular structure that is formed during the reaction but then is converted in the final products.

Usually, these reaction intermediates are unestable and, for that reason, the lifetime of these structures is low.

In the reaction, you can see in the first step C is produced, but also, in the second step reacts producing D. As is produced and, immediately consumed,

<h3>C is the reaction intermediate.</h3>

Antimony has 2 naturally occurring isotopes. The mass of antimony-121 is 120.904 amu and the mass of antimony-123 is 122.904 amu
Sav [38]
Wow, now this one is a hard one, took me quite a while to figure it out but here it is:
120.904(x)+122.904(1-x)=121.76 \\ &#10;120.904x-122.904x+122.904=121.76 \\ &#10;-2x+122.904=121.76 \\ &#10;-2x=-1.144 \\ &#10;x=.572  \\ &#10;1-.572=.428
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%

Calculate the number of moles of H, in 11 L of gas at STP.​
kramer

Explanation:

1 mole of a gas has 22.4 L of volume at STP. Therefore, 0.5 mol of H2 has 0.5 x 6.022 x 1023 = 3.011 x 1023 molecules. Hence, the number of moles, molecules and atoms present in 11.2 liters of H2 at STP are 0.5 , 3.011 x 1023 and 6.022 x 1023 respectively.
