Explanation:
All resources used in making all products can be traced to their natural origin. What differentiates a natural product from a synthetic one is the level of processing that goes into making synthetic products.
- For example, a synthetic product such as plastic is actually derived from natural product.
- Instead of using the sap of rubber plants for making this product, scientists engineered a way to produce plastics from petroleum products which are derived from crude oil.
- Most synthetic products are merely products of alternate source of manufacturing which are well engineered.
Answer:
Group 18th
Explanation:
The group 18th of periodic table which is composed of Noble gases mainly was missing from the Mendeleev's periodic table. The reason for this is that Noble gases are least reactive, therefore, it was difficult to predict such elements which do not react with other elements.
I believe it the answer is 3412

The gas can be decomposed to yield 2.09 parts by mass of uranium for every 1 part by mass of fluorine.If the relative mass of a uranium atom is 238 and the relative mass of a fluorine atom is 19, <span> the number of fluorine atoms that are combined with one uranium atom. is 6</span>
