When the salt gets added to the coke it changes the balance of the its chemistry and forces the release of carbon dioxide bubbles.
The balanced chemical reaction is written as:
3HCl + Al(OH)3 = AlCl3 + 3H2O
We calculate as follows:
1.51 g Al(OH)3 ( 1 mol / 78.01 g ) ( 3 mol HCl / 1 mol Al(OH)3 ) ( 1 L / 0.100 mol HCl ) = 0.581 L of 0.100 M HCl solution is needed
Hope this answers the question. Have a nice day.

FeO is Iron II Oxide. You identify that it's an ionic bond so it won't have any prefixes. By reverse criss-crossing the charges, Iron gets a 1+ charge, and Oxygen gets a 1- charge. Since you know that Oxygen has to have a 2- charge, you multiply the 1+ and 1- by 2 to fix their charges, thus giving Iron a 2+ charge and Oxygen a 2- charge.
Since Iron has a 2+ charge, it's roman numeral is II. So the answer is Iron II Oxide.
The other one is Iron III Oxide. By reverse criss-crossing the charges, Fe geta 3+ charge, and Oxygen gets a 2- charge. Since it's correct, the 3+ charge is the roman numeral. So, the answer is Iron III Oxide.
Answer:
4752 ft/min.
Explanation:
The following data were obtained from the question:
Speed (in mph) = 54 mph
1 mile = 5280 feet
1 hour = 60 minutes
Speed ( in ft/min) =?
Next, we shall convert 54 mph to ft/h. This can be obtained as follow:
1 mph = 5280 ft/h
Therefore,
54 mph = 54 mph × 5280 ft/h / 1 mph
54 mph = 285120 ft/h
Finally, we shall convert 285120 ft/h to ft/min. This can be obtained as follow:
1 ft/h = 1/60 ft/min
Therefore,
285120 ft/h = 285120 ft/h × 1/60 ft/min / 1 ft/h
285120 ft/h = 4752 ft/min
From the calculations made above, 54 mph is equivalent to 4752 ft/min.
