Exposure to small amounts of lead<span> over a long period of time is called chronic toxicity. </span>Lead<span> is particularly </span>dangerous<span> because once it gets into a person's system, it is distributed throughout the body just like helpful minerals such as iron, calcium, and zinc. And </span>lead<span> can cause harm wherever it lands in the body.</span>
When Al(OH)3 and H2SO4 are allowed to react, the products formed are aluminum sulfate (Al2(SO4)3<span> ) and water (H2O). The balanced equation should be written as follows:
</span><span>3H2SO4 + 2Al(OH)3 = Al2(SO4)3 + 6H2O
This reaction is called a neutralization reaction. Hope this answers the question. Have a nice day.</span>
