Question

1. which products best complete the balanced equation between sulfuric acid and sodium hydroxide? h₂so₄ + 2naoh → ? na₂s + 4h₂o na₂so₄ + 2h₂o so₃ + 2nah₃ 2naso₄ + h₂o clear all

Explanation:

Step1: Identify reaction type

It's an acid - base neutralization reaction.

Step2: Determine products

Acid ($H_2SO_4$) reacts with base ($NaOH$) to form salt and water. The salt is formed by the combination of the cation from the base ($Na^+$) and the anion from the acid ($SO_4^{2 - }$), and water is formed from $H^+$ and $OH^-$.

Step3: Balance products

For $H_2SO_4+2NaOH$, the product salt is $Na_2SO_4$ and water is $2H_2O$ to balance the atoms on both sides of the equation.

Answer:

B. $Na_2SO_4 + 2H_2O$
