The component of the dri reflects the requirement of a nutrient for 50 percent of healthy americans and canadians in a specific life stage and gender is Estimated Average Requirement (EAR).
What is EAR?
A daily food intake number known as the Estimated Average Requirement (EAR) is one that is thought to satisfy the needs of 50% of healthy persons in a given life stage and gender group.
Based on a review of the scientific literature, the estimated average requirements (EAR) are predicted to meet the needs of 50% of the population in that age range.
It serves as the foundation for the creation of RDAs and is employed to assess the sufficiency of nutritional consumption for a given population.

Answer:
No
Explanation:
Hello,
Since the sealed glass container is isolated (closed system) no escape of boiled water (steam) was presented, so it is obvious that the alchemists were wrong, it is impossible that the water turns into "earth" because it has components that water does not have by itself (metallic and nonmetallic ions and molecular compounds) that is why the solid residue could have come from suspended solids or simply solids that were initially dissolved and due to the boiling of water, they remained at the bottom of the flask. Nevertheless, the experiment done by Lavoisier was more precise because the conclusion based on the initial and final masses, accounts for the boiling process; besides, the mass agreement substantiates that no mass was removed due to the isolation of the flask.
Best regards.
