Dihydroxyacetone /ËdaÉªhaÉªËdrÉksiËaesÉ¨toÊn/ , ËdaÉªhaÉªËdrÉksiËÃ¦sÉ¨toÊn OR, dha also known as, glycerone is a simple (carbohydrate a) triose with Formula C 3H 6o. 3HA is a hygroscopic white crystalline powder. It has a sweet cooling taste and a characteristic odor. It is the simplest of all ketoses and has no chiral center or optical activity. The normal form is a dimer which is slowly soluble in one part water and 15 parts ethanol.
The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius. It is composed of an ironânickel alloy and some light elements. The temperature at the inner core boundary is approximately 5700 K (5400 Â°C).
Earth is classified as the largest of the terrestrial planets based on its circumference and diameter as well. At the equator, Earth's circumference is 24,901.55 miles (40,075.16 km). It is slightly smaller between the North and South poles at 24,859.82 miles (40,008 km).Earth's diameter at the poles is 7,899.80 miles (12,713.5 km) while it is 7,926.28 miles (12,756.1 km) at the equator. For comparison, the largest planet in Earth's solar system, Jupiter, has a diameter of 88,846 miles (142,984 km).arth's Size. As the largest of the terrestrial planets, Earth has an estimated mass of 5.9736 Ã 10 24 kg. Its volume is also the largest of these planets at 108.321 Ã 10 10 km 3. In addition, Earth is the densest of the terrestrial planets as it is made up of a crust, mantle and core.
