Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydro
Dahasolnce [82]

The product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

<h3>What is the reaction between sulfuric acid and potassium hydroxide?</h3>

The result will be, H+ from H₂SO₄ reacts with OH- from KOH to generate H₂O. Also, K+ reacts with SO₄²⁻ to create K₂SO4₄

As a result, the balanced equation will be:

\rm H_2SO_4 + 2KOH --- > K_2SO_4 + 2H_2O

Thus, the product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. Sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

1.25 is closer to 1.04 or not ?<br> plz heelp
konstantin123 [22]

Answer:

No.

Step-by-step explanation:

When looking at numbers after the decimal point, think of the numbers as real numbers.

In 1.25, think of the .25 as just 25.

Since this is after the decimal point, it is 25 of a 100.

Now, is 25 closer to 4 or not?

Of course, the number has a great distance from 4.
