Answer:
0.006 48 km/s
Explanation:
1. Convert miles to kilometres
14.5 mi × (1.609 km/1 mi) = 23.33 km
2. Convert hours to seconds
1 h × (60 min/1h) × (60 s/1 min) = 3600 s
3. Divide the distance by the time
14.5 mi/1 h = 23.3 km/3600 s = 0.006 48 km/s

Answer:
The answer to your question is [NObr] = 1.41
Explanation:
Data
Kc = 2
[NO] = 2 M
Br₂ = 1.0 M
NOBr = ?
Process
1.- Write the Equation of the Kc
Kc =
2.- Solve for [NOBr]
[NOBr]² =
3.- Substitution
[NOBr]² =
4.- Simplification
[¨NOBr]² =
[NOBr]² = 2
5.- Result
[NOBr] =
[NOBr] = 1.41
