Based on the half-life of the reaction, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.
<h3>What is the half-life of a substance?</h3>
The half-life of a substance is the time taken for half the amount of atoms present in that substance to decay.
The half-life of the reaction is 200 seconds.
After, one half-life, pressure reduces to 0.0500 atm
After, two half-lives, pressure reduces to 0.0250 atm
After, three half-lives, pressure reduces to 0.01250 atm
After, four half-lives, pressure reduces to 0.00625 atm
Time taken = 4 * 200 = 800 seconds
Therefore, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.

Less force, same work
Answer:
192.5 miles
Explanation:
55mph = 55 miles in 1 hour
55 X 3.5 = 192.5
<h2>Answer:</h2>
<h2>Explanation:</h2>
First, let's refer to the distance formula:
, where d is distance, v is velocity or speed and t is time.
Now, let's find the distance covered by each individual speed that the car had:
<h3>1. Speed 1.</h3>
In order to use the formula, we need to convert minutes into hours since the speed is given in km/h.
21.1 min/60= 0.35 h.
Now, apply the distance formula.
d=(0.35h)*(86.8km/h)= 30.38 km.
<h3>2. Speed 2.</h3>
Convert minutes to hours again and do the same calculations.
10.6min/60=0.18h
d=(0.18h)*(106km/h)= 19.08 km.
<h3>3. Speed 3.</h3>
36.5min/60= 0.61h
d=(0.61h)*(30.9km/h)= 18.85 km.
<h3>4. Obtain the total distance.</h3>
The total distance must be given by the addition of all individual distances traveled by the car on each speed:
Total distance= 30.38 km + 19.08 km + 18.85 km= 68.31 km.
