right will be narked as brainliest​

Answer 1

Answer:

metal oxide + water = Metal hydroxide

Answer 2

Explanation:

We have,

X

2

O

3

+3H

2

→2X+3H

2

O

so, moles of X

2

O

3

= 3×moles of H

2

moles of H

2

=

2

6

=3

so,

M

0.1596

=9

where M is a molecular mass of X

2

O

3

Molecular mass of X

2

O

3

= 2×mass of metal + 48

so, on solving both equation we have

mass of metal =55.8amu
