Methane gas reacts with oxygen in a gas stove.
nekit [7.7K]

Hey there!

CH₄ + 2O₂ → CO₂ + 2H₂O

carbon dioxide: product

methane: reactant

oxygen: reactant

water: product

Methane and oxygen are reactants because they are the substances we start with. They are on the side of the equation that the arrow is pointing away from.

Carbon dioxide and water are products because they are the new substances  that are the yields of the equation. They are on the side of the equation that the arrow is pointing towards.

Hope this helps!

Describe a qualitative test for sulfate in alum crystals using ionic reactions of barium chloride (BaCl2)
Lady bird [3.3K]

A qualitative test for sulfate in alum crystals using ionic reactions of barium chloride (BaCl2) is given Ba²⁺(aq) + SO₄²⁻ (aq)  →   BaSO₄(s).

<h3>What is qualitative test?</h3>

Qualitative test measures changes in color, melting point, odor, reactivity, radioactivity, boiling point, bubble production, and precipitation of the sample.

<h3>Qualitative test for sulfate in alum crystals </h3>

When an aqueous solution of a barium salt (BaCl₂) is mixed with an aqueous solution containing sulfate, a white precipitate of insoluble BaSO₄ forms according to the net ionic equation given below;

Ba²⁺(aq) + SO₄²⁻ (aq)  →   BaSO₄(s)

Thus, a qualitative test for sulfate in alum crystals using ionic reactions of barium chloride (BaCl2) is given Ba²⁺(aq) + SO₄²⁻ (aq)  →   BaSO₄(s).

Wind erosion
Agata [3.3K]

Answer:

removes the fertile B horizon of soil

Explanation:

<em>Wind erosion has the capacity to remove the fertile B horizon of the soil.</em>

The term wind erosion generally refers to the capacity of high-magnitude wind to cause damages to the terrestrial environment. Soils can get their topmost layers removed by a strong wind if there are no barriers such as vegetation to break the speed of the wind.

The topmost layers in most cases consist of humus and the fertile minerals from parent materials. When the topmost layer is lost, the soil becomes unproductive for agriculture.
