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
I'm going to suppose you want the adjusted chemical reaction, using the formulas of the compounds. You can see it in the image attached.
<span>Hind limbs will typically be stronger than forelimbs. For some animals this is because they are used for self-defense (a horse or donkey kicking, for example). Forelimbs are not going to be as strong and are often used for feeding oneself, and not intended to be as weight bearing in many mammals.</span>
