Answer:
66.57%
Explanation:
The decomposition reaction of calcium carbonate is shown below as:
Calculation of moles of 
:
Amount = 3.32 g
Molar mass of = 100 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
According to reaction,
0.0332 moles of decomposes to yield 0.0332 moles of 
Theoretical yield = 0.0332 moles
Calculation of moles of formed as:
Amount = 1.24 g
Molar mass of = 56 g/mol
The formula for the calculation of moles is shown below:
Thus, moles are:
Experimental yield = 0.0221 moles
Thus,
<u>Percent yield = 66.57%</u>
D Snack Mix because they are individual parts that can easily be seperated
Answer:
Explanation:
Hello,
In this case, given that 1 kilometer equals 1000 meters, 1 meter equals 3.281 feet and 1 hour equals 3600 seconds, the required velocity in feet per second turns out:
Regards.
The correct answer is; Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.
Further Explanation:
Hydroelectric power is being used more in recent times than in the past. Hydroelectric power is a more cleaner energy source than the coal plants that produce electricity.
Hydroelectric power plants are built within a dam system and uses the water as source of energy. The water goes into channels created that hits the turbines, the turbines are then moved around by the water and these are connected to the large generators and this produces electric. There are many new hydroelectric plants being built. One of the newest hydroelectric power plants is located in Pella, Iowa.
