Answer:
The middle Hydrogen atom is bonded to two instead of one atom
Oxygen is bonded to one instead of two atoms
Oxygen has three instead of two lone pairs of electron.
Explanation:
If we look at the structure, we will notice that it does not satisfy the basic principles of valency.
Hydrogen has a valency of 1. However, the middle hydrogen atom is bonded to two atoms instead of only one atom - the other atom of hydrogen and an atom of oxygen.
Secondly, oxygen has three lone pairs instead of two lone pairs, hence it is bonded to only one instead of two atoms. This does not correspond to the known valency of oxygen.
Answer:
Dmitri Mendeleev
Explanation:
Dmitri Mendeleev published the first recognizable periodic table in 1869, developed mainly to illustrate periodic trends of the then-known elements. He also predicted some properties of unidentified elements that were expected to fill gaps within the table. Most of his forecasts proved to be correct
Answer: you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density. How can you tell if something will float in water?
