The minimum mass of ethane that could be left over by the chemical reaction is zero.

Explanation:

$2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O$

Moles of ethane = $\frac{23.0 g}{30 g/mol}=0.7666 mol$

Moles of oxygen gas :

$\frac{147.0 g}{32 g/mol}=4.59375 mol$

Since, 2 moles of ethane gas react with 7 moles of oxygen gas.

Then 0.7666 mol of ethane gas will react wit:

$\frac{7}{2}\times 0.7666 mol=2.6831 mol$

This means that ethane gas is in limited amount.hence ethane is a limiting reagent. Where as oxygen in present in excessive amount.

All the moles ethane gas will go under combustion reaction leaving zero moles behind.

628

Step-by-step explanation:

1) Find the circumference of the wheel (the distance it travels in 1 revolution)

$C=\pi d$ where d is the diameter

Plug in 2 ft as the diameter

$C=(3.14) (2)\\C=6.28$

Therefore, the circumference of the wheel is 6.28 ft.

2) Multiply the circumference by 100

6.28 × 100

= 628 ft

Therefore, Joe would travel 628 feet if his wheel turns exactly 100 complete revolutions in one direction.

I hope this helps!
