What would you expect to see if you performed the chemical reaction shown below? 2H2O2 —> H2O(l) + O2(g)
- solid precipitate forming in a liquid
- no detectable change
- bubbles forming in a liquid
- color change in a liquid

Think about it. O2 is a gas so I would expect to see bubbles rising through the liquid.
Thank you
How much solid will be left in a
beaker if you evaporate all the water

sodium chloride? (The molar mass of
NaCl is 58.44 g/mol)
a. 5.84 g
b. 58.4 g
c. 11.7 g
d. 18.9 g
