Answer:
C) 7 to 1
Explanation:
The periodic trend of Atomic Radii for the Periodic Table of Elements is down and to the left the atomic radii increases.
So, from period 1 to 7 and group 18 to group 1, the atomic radii increases.
The opposite (decreasing) would be from period 7 to 1 and group 1 to group 18.
Therefore, our answer is C.
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
Hydrogen and carbon because they are the most common element of canyon
