Answer:
CrO₃.
Step-by-step explanation:
First, we will find the chromium percentage in the oxide by using the following process:
Oxygen (O) = 48%
Chromium (Cr) =?
The oxide consists solely of chromium and oxygen, and its chromium percentage is calculated as:
Cr = 100 – percentage of oxygen
Cr = 100 – 48
Cr = 52%
Next, we will determine the empirical formula for the oxide:
Chromium (Cr) = 52%
Oxygen (O) = 48%
Now, we divide by their molar mass:
Cr = 52/52 = 1
O = 48/16 = 3
Now, divide by the lowest value:
Cr = 1/1 = 1
O = 3/1 = 3
Thus, the empirical formula for the oxide is CrO₃.
Answer:
16 cubic feet per hour
Step-by-step explanation:
This involves a straightforward conversion from inches to feet.
Step 1: Establish the conversion scale
---> the volume of water in 1 minute is 462 cubic inches
--->1 cubic foot = 1728 cubic inches
--->1 hour consists of 60 minutes,
Step 2: Determine the volume in feet per hour
Volume of water in one hour = 0.0347 x 462
---> the amount of water in 1 hour = = 16.0314 cubic feet
---> Rounded to--> 16 cubic feet
Thus, 462 cubic inches per minute equates to 16 cubic feet of water on an hourly basis
