Question

classify the following reaction and balance the equation by entering the smallest possible integer coefficients. hclo4(aq) + ba(oh)2(aq) → ba(clo4)2(aq) + h2o(l) reaction type: 2 item attempts remaining. use the references to access important values if needed for this question.

Explanation:

Step1: Identify the reaction type

This is an acid - base neutralization reaction as an acid ($HClO_4$) reacts with a base ($Ba(OH)_2$).

Step2: Balance the equation

For the reaction $HClO_4(aq)+Ba(OH)_2(aq)
ightarrow Ba(ClO_4)_2(aq) + H_2O(l)$, balance the $ClO_4^-$ ions first. There are 2 $ClO_4^-$ in $Ba(ClO_4)_2$, so we need 2 moles of $HClO_4$. Then balance the hydrogen and oxygen. The balanced equation is $2HClO_4(aq)+Ba(OH)_2(aq)
ightarrow Ba(ClO_4)_2(aq)+2H_2O(l)$.

Answer:

Reaction Type: Acid - base neutralization
Balanced equation coefficients: 2, 1, 1, 2
