The reaction of a metal with oxygen to form rust is called as redox reaction.

Explanation:

The process during which the surface of metal reacts with the oxygen ions present in air, it has tendency to get oxidized that is formation of an oxide layer on the surface of the metal. Generally, it occurs when metals like iron comes in contact with moisture or water. So the oxygen in moisture reacts with iron giving its electron and getting oxidized and reducing the surface of metal by forming metal oxide. So the complete process of formation of rust is termed as redox reaction. As here both oxidation and reduction is taking place.

Using the equation 2H2 + O2 --> 2 H2O, if 192 g of O are produced, how many grams of hydrogen must react with it? Help me und

Mamont248 [21]

To produce a molar conversion, you need to know the molar mass of each molecule. I presume you mean there are 192 grams of O2. The molecular weight of oxygen is 16 g/mol. Therefore, O2 is 32 g/mole.

If there are 192 grams of O2, then:
192 grams x (1 mole/32g) = 6 moles of O2.

To react each mole of oxygen, you need 2 moles of hydrogen (H2). You can see this in the equation 2H2 + O2 --> 2 H20.
To react 6 moles of O2, you need 12 moles of H2.
Now that we have the total moles of hydrogen needed, we now use the molar mass of H2 (2 grams/mole)
12 moles H2 x (2 grams/1 mol H2) = 24 grams of H2.

Write a chemical equation showing how each behaves as an acid when dissoblbed in water.

nikdorinn [45]

Answer:

a. H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)

b. NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)

Explanation:

According to Bronsted-Lowry acid-base theory,

An acid is a substance that donates a H⁺.

A base is a substance that accepts a H⁺.

a. When dissolved in water, H₂S behaves as an acid according to the following equation.

H₂S(aq) + H₂O(l) ⇄ HS⁻(aq) + H₃O⁺(aq)

b. When dissolved in water, NH₄⁺ behaves as an acid according to the following equation.

NH₄⁺(aq) + H₂O(l) ⇄ NH₃(aq) + H₃O⁺(aq)
