1) chemical A was a white powder and Chemical B was a  yellow liquid

2)I think that it was a physical change because you mixed the too chemicals together

3) I think that obelisk is a both a solid and a liquid because when you were moving tor making it into a ball it would turn into a solid but when you stopped it would turn into a liquid

4)  I understand KMT with the oobelck and how the states of matter go with it like how not always moving the obelisk makes it turn into a solid and when you just eave it it turns into a liquid
