Question

When metal X reacted with oxygen, it gives a metal oxide Y which dissolves in water and

readily gives an alkali Z. (Atomic mass of X is 23). Identify X, Y, Z and write the chemical

equations involved.
​

Answer 1

Answer:

X= Na (sodium)

Y= Na2O(sodium oxide)

Z= NaOH(sodium hydrooxide)

Answer 2

X=sodium(Na)
Y=sodium oxide(Na2O)
Z=Sodium hydroxide(NaOH)
