Mass Ag₂O needed = 107.416 g
<h3>Further explanation</h3>
Given
100 g Ag
Required
mass of Ag2O
Solution
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
mass of Ag in Ag2O :
= ((2 x Ar Ag)/molar mass Ag2O )x mass Ag2O
Ar Ag : 107,8682 g/mol
MW Ag₂O = 231,735 g/mol
Input the value :
mass Ag₂O=(mass Ag x MW Ag₂O) : (2 x Ar Ag)
mass Ag₂O = (100 g x 231,735 g/mol) : ( 2 x 107,8682 g/mol)
mass Ag₂O = 107.416 g
Answer:
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

The compound NaH2PO4 name is
sodium dihydrogen phosphate
Explanation
This name is arrived at by using the IUPAC rules of naming compound
1. the metal (sodium)is named first followed by the ligand ( hydrogen and phosphate)
Ligand are molecules that are attached to the metal center.
2. ligand are named using alphabetical order(for our case h for hydrogen come before p for phosphate hence hydrogen is named first)
3. Prefix di is used since hydrogen are two
hence the name of the compound is Sodium dihydrogen phosphate
Answer:
8.4
Explanation:
-log(4.08x10^-9) = 8.4

All other elements react with other elements to form compounds. In the special case where the reaction produces fixed numbers of the same types of atoms in exactly the same configuration, we say the elements have formed a molecule.
