1. For one atom of lithium -6 I will need atom of lithium -7 for an average atomic mass of 6.944? 2. For one atom of lithium -6 needed Adams of lithium -7 for an average atomic mass of 6.944.

For one atom of lithium -6 I will need_16.85____ atom of lithium -7 for an average atomic mass of 6.944 .

Explanation:

1 ) Let required atom be m .

6 + 7m = 6.944 + 6.944m

7 m - 6.944 m = .944

.056 m = .944

m = 16.85

Explanation:

Most nonmetal oxides are acidic, but not all.

Such a molecule readily loses a proton from one of its hydroxy groups because the resulting anion is highly stabilized by the oxygen atoms and the electronegative nonmetal atom. Therefore, it's acidic.

Example ;

Silicon, phosphorus, sulfur, and chlorine oxides are acidic. Some non-metal oxides, such as nitrous oxide (N2O) and carbon monoxide (CO), do not display any acid/base characteristics.

( when Sulfur dioxide is dissolved in water it leads to the formation of sulfurous acid solution which is acidic in nature.)
