Answer: The theoretical yield is 6 rings.
Explanation:
Theoretical yield is predicted or estimated value.
Jeweler used 2 sapphires for 1 ring
Then for each sapphire there will be = 
rings are used
For 12 sapphire = 
will be used
Out of 10 rings 6 rings with 2 sapphires will be made.
The theoretical yield is 6 rings.
Answer:
10.6 moles of CO₂ are produced in this combustion
Explanation:
The combustion reaction is:
2C₂H₆ (g) + 7O₂ (g) ⟶ 4CO₂ (g) + 6H₂O (g)
We assume the ethane as the limiting reactant because the excersise states that the O₂ is in excess.
We make a rule of three:
2 moles of ethane can produce 4 moles of CO₂
Therefore 5.30 moles of ethane will produce (5.3 . 4) /2 = 10.6 moles
Answer:
Coefficient
Explanation:
I am not that sure, but just wanted to help.
The midpiece of the sperm is packed with mitochondria. Mitochondria are organelles in the cell that produce energy. Sperm use the energy in the midpiece to move. The tail of the sperm moves like a propeller, around and around.
