I’m really stuck on ((40 possible points))

(a) 1.0 g/cm³; (c) 7.0 s  

Explanation:

(a) g/cm³

Yes, this is possible.

(b) dL²/L

No, this is not possible.

The two measurements have the same base unit, so you must express both in the same base units or derived units.

(c) s³/s²

Yes, this is possible.

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.

20 drops hope this
