Answer:
Mineral hydration.
Explanation:
Mineral hydration is a chemical reaction where water is added to the crystal structure of a mineral, usually creating a new mineral sometimes called a hydrate. The process called mineral hydration is known as retrograde alteration and is a process occurring in retrograde metamorphism.
Examples are: Silicates - Chlorites and Non-sillicates - Carbonates, oxides etc.
Hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water is because the <span>very active metals react with water. For example, calcium reacts with water to form calcium hydroxide and hydrogen gas etc. </span>
Answer:
Explanation:
4NH₃ + 7O₂ --> 4NO + 6H₂O
4 moles 7 moles
58.3 g of NH₃ = 58.3 / 17 = 3.43 moles
126 g of O₂ = 126 / 32 = 3.94 moles
4 moles NH₃ requires 7 moles of O₂
3.43 moles NH₃ requires 6 moles O₂
Available O₂ is only 3 94 moles , so O₂ is in short supply .
Hence O₂ is the limiting reagent .
Answer:
Dry desert air cools much more quickly resulting in much colder nighttime temperatures.
Explanation:
The higher the moisture content in the air the harder it is to cool. Water has a much greater specific heat than dry air, retaining much more energy for each degree of temperature.
