Answer:
- <em><u>Step 2 (the slow step).</u></em>
Explanation:
The rate-determining step is always the slow step of a mechanism.
That is so, because it is the slow step which limits the reaction.
Imaging that for assembling a toy you have process of three steps:
- 1. order ten pieces, which you can do in 1 minute: meaning that you can order order the pieces for 60/1 = 60 toys in 1 hour.
- 2. glue the pieces and hold the toy until the glue hardens, which takes 1 hour: meaning finishingh 1 toy in 1 hour.
- 3. pack the toy, which takes 2 minutes: meaning that you can pack 60/2 = 30 toys in one hour.
The time to glue and hold one toy until the glue hardens determines that you can assemble 1 toy in 1 hour and not 60 toys or 30 toys.
Thus, the step that determines the rate at which the reaction happens is the slowest step: step 2.
According to periodic trends, bismuth has the greatest atomic radius.
Answer: The sun
Explanation:
its the real boss of the water cycle, and it doesn't even live here on Earth. The sun provides heat, or energy, which is what makes the water cycle work. The sun's heat allows water to change forms from liquid to gas to ice and back again.
Yes MgF2 is a pure substance
Answer:
<h2>1.806 × 10²³ atoms</h2>
Explanation:
The number of sodium atoms can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.3 × 6.02 × 10²³
We have the final answer as
<h3>1.806 × 10²³ atoms</h3>
Hope this helps you
