Answer:
As you used two diferent instruments, one is more sensitive than the other.
Explanation:
The sensitivity of an instrument is the minimum amount of magnitude that can be differentiate a measurement system.
In method A, you got 27 cm, so if in method B, you got 27.00, method B is more sensitive. It's like saying that one system measures more than the other
Answer : The mass of the 3.7 mole of is, 885.04 grams
Solution : Given,
Moles of = 3.7 moles
Molar mass of = 239.2 g/mole
Formula used :
Now put all the given values in this formula, we get the mass of
Therefore, the mass of the 3.7 mole of is, 885.04 grams
Answer:
The minimum mass of ethane that could be left over by the chemical reaction is zero.
Explanation:
Moles of ethane =
Moles of oxygen gas :
Since, 2 moles of ethane gas react with 7 moles of oxygen gas.
Then 0.7666 mol of ethane gas will react wit:
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.
Answer:
I would say about 33% which is A.
