Answer: 125 g
Explanation:
To calculate the moles :
The balanced reaction is:
According to stoichiometry :
1 mole of 
require = 3 moles of 
Thus 1.30 moles of will require=
of
Mass of 
Thus 125 g of will be needed to burn 36.1 g of
Answer:
True
Explanation:
The accuracy level is usually determined by the difference between the experimental and correct value. It is important to note that the smaller the difference between the average experimental value and the correct (true) value, the more accurate it is.
When the difference is large then it means the accuracy level is low and not up to the required standard.
