PLEASE ANSWER NOW Use the information, Image, and table to answer the following question.
Students are attempting to demonstrate a reaction of liquid water separating into hydrogen and oxygen gases:
Investigation Step
Procedure
Pour water into a beaker with a small amount of salt and place the beaker on a digital
1
scale to record the mass.
2
Place two electrodes connected to a battery to create an electric current in the water.
3
Seal the top of the beaker, and observe for any gas bubbles forming in the liquid water.
What type of reaction does this investigation demonstrate, and as time progresses what will happen to the mass reading on
the scale?
O A This is a decomposition reaction and the mass reading will stay the same as time progresses.
OB. This is a decomposition reaction and the mass reading will decrease as time progresses.
O C. This is a synthesis reaction and the mass reading will stay the same as time progresses.
OD. This is a synthesis reaction and the mass reading will decrease as time progresses,
