Chemistry Homework:I need help determining the diffrence in heterogeneous & homogeneous

mixtures! EASY 10 PNTS? Okay so I know homogeneous mixtures are the same throughout and heterogeneous mixtures are not the same throughout. But, Im having trouble with a few of my homework questions. Ive already answered and classified 15 things on this worksheet as homo/heterogeneous but Im not sure about these 5. Please tell me which are homo and which are hetero. Thanks and 10 points to anyone who can successfully help me.
