Zircon is one of the oldest known gemstones, with some crystals dating back more than four billion years. It contains traces of uranium, allowing scientists to accurately date how old it is. However, while zircon is one of the oldest minerals on earth, gemstones like diamonds, sapphires, and rubies have also been found in extremely old geological formations. So while zircon is incredibly old, it may not be accurate to definitively say it's the oldest gemstone.

Low carbon dioxide levels in the blood indicate a condition known as hypocapnia. This is often caused by hyperventilation or breathing too rapidly, which makes you eliminate more carbon dioxide than you produce. The common symptoms include light-headedness, tingling sensations, shortness of breath, and confusion. In severe cases, hypocapnia can lead to health problems like hypoxia or shortage of oxygen in the body or more potentially, it can disturb the acid-base balance resulting in alkalosis. It's essential to address the underlying issues leading to hypocapnia, like anxiety or panic disorder, lung diseases etc. Please, consult a doctor for a comprehensive evaluation if you're experiencing these symptoms.

[Compact Response]
Producing a 50/50 mixture of methanol and water is a straightforward process often used for various applications like fuel blends or antifreeze. Here's a simple method:

1. Safety First: Wear protective gear like gloves and goggles since methanol is toxic and flammable.

2. Measure Accurately: Gather equal volumes of methanol and water. You can use a graduated cylinder or a measuring cup for precision.

3. Mixing: Pour the methanol into a clean, non-reactive container (preferably glass or plastic). Slowly add the water while stirring gently to combine.

4. Double-check: Verify the ratio before use. If needed, use a hydrometer to measure the solution's specific gravity.

Remember, this mixture can be hazardous; handle it with care, store it properly, and avoid ingestion or skin contact.
