Answer 2

The two chemical equations you provided are balanced chemical equations that represent chemical reactions. Here they are with their balanced coefficients:

1. BaCl2 + H2SO4 → BaSO4 + 2HCl
2. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl

Let's break down each reaction:

1. BaCl2 + H2SO4 → BaSO4 + 2HCl

In this reaction, barium chloride (BaCl2) reacts with sulfuric acid (H2SO4) to form barium sulfate (BaSO4) and hydrochloric acid (HCl). The balanced equation shows that one mole of BaCl2 reacts with one mole of H2SO4 to produce one mole of BaSO4 and two moles of HCl.

2. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl

In this reaction, iron(III) chloride (FeCl3) reacts with sodium hydroxide (NaOH) to form iron(III) hydroxide (Fe(OH)3) and sodium chloride (NaCl). The balanced equation indicates that one mole of FeCl3 reacts with three moles of NaOH to yield one mole of Fe(OH)3 and three moles of NaCl.

It's important to note that chemical reactions should be carried out in a controlled laboratory environment by trained professionals, as some reactions may produce hazardous materials or release toxic gases.
