FLOOR. Most of the molecules that dont sick to something fall on the floor so most would be on the FLOOR.
Can you give me the anwsers
If you mean the number of Significant Figures/Digits in 23.45, it would be 4. This is because every single non-zero digit is counted as a significant figure
When a monovalent cation X binds to a divalent anion Y, a compound with the formula
would be formed.
A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be 
A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be 
Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of
would be required to successfully bind
