Answer:
add a subscript of 4 after the O
Explanation:
The chemical formula of a compound is said to contain the elements in that compound with the respective number of atoms in each element. When writing chemical formula of a compound, the chemical symbols of each comprising element must be known. In this case involving Phosphorus tetraoxide, the symbols of the elements in this compound has been identified as P for Phosphorus and O for oxygen.
After identification of elemental symbols in the compound, Sebastian must now allocate the number of atoms that each element contains. According to the name of the compound, TETRA preceding oxygen means four (4), hence, four will be added as a subscript to O. Hence, at the end, the chemical formula will be PO4.
Please note that, the order of the chemical formula will go as the name implies Phosphorus tetraoxide, so phosphorus symbol (P) comes first, followed by oxygen symbol (O)
1.Vitamin C (ascorbic acid)
Chemical formula of vitamin C is C6H8O6
Two elements found in vitamin C are Carbon and Hydrogen
2. Vitamin B12 (Cyanocobalamin)
Chemical formula of vitamin B12 is C63H88CoN14O14P
Two elements found in vitamin B12 are Phosphorous and Cobalt. Of these two elements, Cobalt is a trace element and is found right at the center of this vitamin.
3. Vitamin E (alpha-Tocopherol)
Chemical formula of vitamin E is C29H50O2
Two elements found in vitamin E are Hydrogen and Oxygen.

Explanation:
Large electrical shifting magnets have concentrated retaining strength to lift dense, ferric objects and a deep-reaching magnetization. An immensely useful materials management technique is these electromagnetic rises.
Answer:
20 meters per second
Explanation:
If an object accelerates for 2 seconds, and accelerates by 10 meters per second, then that objects speed will be 20 meters per second, assuming hat there are no other factors involved.
