Each incomplete reaction is a neutralization reaction. Match each equation with the salt formed. 1. H2SO4 + 2NH4OH → ? 2. 2NaOH
sergey [27]

1. H₂SO₄ + 2NH₄OH ⟶ (NH₄)₂SO₄ + 2H₂O


2. 2NaOH + H₂CO₃ ⟶ Na₂CO₃ + 2H₂O


3. HNO₃ + KOH ⟶ KNO₃ + H₂O


<em>Explanation</em>:

Acid + base ⟶ salt + water


Take the H from the acid and the OH from the base to get water.


Then, join what’s left to get the salt. Write the symbol for the metal first.


For example, in equation 3, take the H from HNO₃ and the OH from KOH.


Combining the remaining parts (NO₃ and K) to get the salt, KNO₃.

How do I do 2 and 4 I don’t understand how to solve it

For question two, you figure out the amount of sodium atoms on the left and right side and the amount of oxygen atoms on the left and right side

So for two it would be 4, 1, 2

For question four, you figure out the amount of atoms on each side

So for four it would be 1, 2, 1, 2

An unknown substance turns blue litmus paper to red. Which additional test could be used to confirm the substance identity
alexandr1967 [171]

The additional test is that it should turn methyl orange to red because it is an acid.  

The mentioned substance given in the test is an acid, as the bases turn red litmus paper blue, while an acid turns blue litmus paper red. The acid-base indicators are generally weak bases or acids and they function as a chemical detector for hydronium and hydrogen cations.  

Phenolphthalein is an example of an acid-base indicator, it becomes pink in basic solutions and colorless in acidic solutions. Methyl orange is another example, which becomes yellow in basic solutions and red in acidic solutions.
