Question

Write the equation for the dissolution or the following in water, a group 1 Metal shows as X and a Group 16 element shown here as Y

X2Y

Answer 1

Molecular equation: \[X _{2}Y + 2 H _{2}O \rightarrow 2XOH + H _{2}Y\]
Ionic equation: \[2X ^{+} + Y ^{2-} + 2 H _{2}O \rightarrow 2X ^{+}+2OH ^{-} + 2H _{2}S\]

Answer 2

Small correction in the Ionic equation:
\[2X ^{+} + Y ^{2-}+ 2H _{2}O \rightarrow 2X ^{+} + 2OH ^{-} + H _{2}Y\]

Answer 3

Thank you!
