M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
<span>An element is made of only one kind of atom, while a compound contains the atoms of two or more elements. For example, gold is made of only one kind of atom, so it is an element, but water is a mix of hydrogen and oxygen, so it is a compound.</span>
A change of one unit on the pH scale represents a change in the concentration of hydrogen ions by a factor of 10, a change in two units represents a change in the concentration of hydrogen ions by a factor of 100. Thus, small changes in pH represent large changes in the concentrations of hydrogen ions.
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
If Im not wrong i think its rain,snow,hail,and sleet...hope this helps you
