Answer:
index
Explanation:
index is usually found in the back of a book
Answer:
Explanation:
The time when they meet is t in hours
The general formula for both cars is d = r*t
t is unknown
r1 = 55 mph
r2 = 60 mph
60 mph * t + 55 mph*t = 100 miles
t * (60 mph + 55 mph) = 100 miles
t * 115 = 100 miles
t = 100 miles / 115 mph
t = 0.8696 hours
1 hour has 60 minutes
0.8696 hour = x
x = 0.8696 hours * 60
x = 52 minutes and 10 seconds
They will meet at 2:52:10
You have to give answers to get the time to agree.

The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L
