Answer:- HBr is limiting reactant.

Solution:- The given balanced equation is:

2Al+6HBr\rightarrow 2AlBr_3+3H_2

From this equation, There is 2:6 mol or 1:3 mol ratio between Al and HBr. Since we have 8 moles of each, HBr is the limiting reactant as we need 3 moles of HBr for each mol of Al.

The calculations could be shown as:

8molAl(\frac{6molHBr}{2molAl})

= 24 mol HBr

From calculations, 24 moles of HBr are required to react completely with 8 moles of Al but only 8 moles of it are available. It clearly indicates, HBr is limiting reactant.

Lady bird [3.3K]
Units of measure is defined as a the magnitude of a certain quantity. There are a lot of units that we can use for mass. Kilograms, grams, tons, pounds and slugs are some of the examples. There are some units where certain prefixes changes its magnitude. One thousand grams is one kilogram. One thousand mg is one gram. 5.63 grams is 5,630 mg and 0.00563 kg is 5.63 grams. Hence the answer here is 0.563 hg.
