Copper(ii) sulfate forms a bright blue hydrate with the formula cuso 4 ⋅ n h 2 o ( s ) . if this hydrate is heated to a high enough temperature, h 2 o ( g ) can be driven off, leaving the grey‑white anhydrous salt cuso 4 ( s ) . a 14.220 g sample of the hydrate was heated to 300 ∘ c . the resulting cuso 4 ( s ) had a mass of 8.9935 g . calculate the val

The value of n in the hydrate formula is 5 ,.

Explanation:

Mass of hydrate of copper sulfate = 14.220 g

Moles of hydrate of copper sulfate =

Mass of copper sulfate after heating = 8.9935 g

Moles of copper sulfate =

Solving for n, we get:

n = 5

The value of n in the hydrate formula is 5 ,.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
