Answer:
Cryogenic Liquids
Explanation:
Liquid oxygen and liquid nitrogen are prepared via the cryogenic distillation of air.
Answer:
The titration process has quite a few real-world uses, including key roles in the food industry and medical community. The titration process is essentially an analytical technique, as it is used to determine a chemical or physical property of a chemical substance, element, or mixture (such as food). Specifically in the food industry, it is used to allow food manufactuers to determine the quantity of a reactant in a sample. To provide an example, it can be used to find the specific amount of stuff that is usually labeled on the nutrition label, such as sugar, salt, protein, calcium, vitamin C, etc. As for the medical world, pharamcists typically use this process to get the proper mix when compounding medicines. It is used to get the necessary proportions in intravenous drips.
It is called a physical change. It is reversible and doesn't affect the chemical make-up.
0.22 moles of Al₂(CO₃)₃
Explanation:
The decomposition reaction of aluminium carbonate (Al₂(CO₃)₃):
Al₂(CO₃)₃ → Al₂O₃ + 3 CO₂
Taking account the chemical reaction we devise the following reasoning:
if 1 mole of Al₂(CO₃)₃ produces 3 moles of 3 CO₂
then X moles of Al₂(CO₃)₃ produces 0.65 moles of 3 CO₂
X = (1 × 0.65) / 3 = 0.22 moles of Al₂(CO₃)₃

Answer:
natural selection
Explanation:
hybrid incompatibility does not evolve because of direct natural selection for hybrid incompatibility, but is instead a by-product of other evolutionary divergence between the species
