How much sulfuric acid (in grams) could be produced from oxygen and water reacting with 2.50 g of SO2?

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
