Answer:
2.92 mol
Explanation:
Step 1: Write the balanced equation
2 B(s) + 6 HCI(aq) ⇒ 2 BCl₃(aq) + 3 H₂(g)
Step 2: Establish the appropriate molar ratio
The molar ratio of hydrochloric acid to boron chloride is 6:2.
Step 3: Calculate the moles of boron chloride produced from 8.752 moles of hydrochloric acid
![8.752molHCl \times \frac{2molBCl_3}{6molHCl} = 2.92molBCl_3](https://tex.z-dn.net/?f=8.752molHCl%20%5Ctimes%20%5Cfrac%7B2molBCl_3%7D%7B6molHCl%7D%20%3D%202.92molBCl_3)
HBr (aq) is an Arrhenius acid.
