11. I would say physical because the color of the item is changed and the texture and density is changed aswell.
The correct answer is C) Bee, any living thing, such as a bee, cannot make its own food therefor it is a consumer
B) The elements become less reactive.
According to the law of conservation of mass, the quantity of the elements, involved in chemical reactions does not change. For example,
H2O2 - > H2O + O2
is wrong, because there are two O atoms on the first side of the equation, and three on the other. To correct it, coefficients must be added, until the amount of both H and O atoms is equal on both sides.
2H2O2 - > 2H2O + O2
