can someone please help? i’m failing so bad in science and will appreciate anyone who helps, and will make you a brainliest.

Write the complete balanced equation for the reaction between lead (iv) oxide (pbo2) and water (h2o).

What state of matter is ice a. liquid b. element c. solid d. gas

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
