Answer = 43.2
Because to find the mass you multiply the amount of moles ( 1.6) by the mass of the element ( mass of aluminium is 27) so

<u>Answer:</u>
<em>Burning gas on a stove top transforms chemical energy into thermal energy.</em>
<u>Explanation:</u>
Cooking food involves in two types of energies. <em>They are chemical energy and thermal energy.
</em>
We use gas for a gas stove.Here gas is chemical energy.when we light the stove the fire lits up and here the <em>chemical energy energy is converted into thermal energy.</em>
Breaking and combining of bonds during combustion gives heat and light.This thermal energy heats the vessels and cooks the food through the <em>process of conduction, convection and radiation.
</em>
Answer is: 0,1053 <span>moles of hydrogen are produced.
</span><span>
Chemical reaction: </span>2NH₃ → 3H₂ + N₂.<span>
n(N</span>₂) =
0,0351 mol..<span>
From chemical reaction: n(N</span>₂) : n(H₂) = 1 : 3.
n(H₂) = 3 · 0,0351 mol.
n(H₂) = 0,1053 mol.
n - amount of substance.
