4% starch solution will decrease in volume.
This is because the less starch concentration, the more water molecules exists. Since 4% is less than 10%, so the 4% will contain more water. Water molecules tend to flow from a region of higher water potential to a region of lower water potential through the semi permeable membrane in osmosis. Therefore, since the 4% contains more water, the water there will flow away from the 4% and to the 10% one in order to reach equilibrium.

Here are some disadvantages, is that nitrogen dioxide is a toxic gas and it can still be harmful when ingested by human, also critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions.
