Write the equation for the decomposition of water into its elements. phase symbols are optional.

2H₂O (l)2 H₂(g)    +     O₂ (g)

Explanation:

Here , liquid water is decomposed through the application of heat to form two gaseous products - Hydrogen gas and Oxygen gas. The reaction coefficients also show that  2 moles of water decompose to form 2 moles of Hydrogen gas and I mole of Oxygen gas.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
