Question

3. Answer the following questions regarding the chemical reaction below. (20 points)

A. Balance the following chemical reaction equation: H2(g) + O2(g) → H2O(l) (3 points)

To balance the equation the number of molecules of each element have to be equal on both sides:

2H2O ==> 2H2 + O2

B. What type of reaction is this? (1 point)

Its a decomposition reaction.

C. What type of bond is formed between atoms of a molecule of the product of this reaction? How can you determine which type of bond is formed between these atoms? (4 points)

There are two types of bonds created by atoms of the molecules are polar covalent bond and hydrogen bond. Polar covalent bond is formed by the hydrogen and oxygen of the water while the hydrogen bond is formed between the water molecules.

D. According to the rules for naming compounds that you learned in this course, what is the chemical name of this product? What is its common name? (2 points)

Answer 1

If it's H2 + O2 --> 2(H2O), then the compound that was formed is called dihydrogen monoxide. Commonly referred to as water.
