Answer:
Al(OH)₃(aq) + 3 HBr(aq) ⇒ AlBr₃(aq) + 3 H₂O(l)
Explanation:
Let's consider the unbalanced equation for the reaction between solid aluminum hydroxide and a solution of hydrobromic acid. This is a neutralization reaction so it forms a salt, aluminum bromide, and water.
Al(OH)₃(aq) + HBr(aq) ⇒ AlBr₃(aq) + H₂O(l)
We start balancing Br atoms by multiplying HBr by 3.
Al(OH)₃(aq) + 3 HBr(aq) ⇒ AlBr₃(aq) + H₂O(l)
To get the balanced equation, we must multiply H₂O by 3 as well.
Al(OH)₃(aq) + 3 HBr(aq) ⇒ AlBr₃(aq) + 3 H₂O(l)
Answer:
Mineral dusts are solid particles, that may become airborne depending upon their origin and the surrounding physical conditions. Lead is potential poison. It is obtained from the earth crust. The lead poisoning is a popular occupational hazard.
