Is ice in a glass of water a substance or mixture?
if you are comparing the water and Ice then it is neither. they are both the same.From one point of view you have a mixture - even though they are the same - one is in the solid state and the other is in the fluid state.From another - its an homogeneous substance since they are the same element.To be literal as to your question: which is about the ICE itself and the water is not actually the substance in question. With that then the Ice is a substance and as long as it is ICE is is not mixing with the water. When the state changes from solid to liquid the melted liquid has become the other substance and is no longer ICE.

What type of mixture is smog?
Smog would be classified as a homogeneous mixture because you cannot distinguish particles from eachother. It looks like one substance hovering over cities. Being able to see different substances obviously would make it a heterogeneous mixture. not to try and confuse you, but if you had better means to analyse the smog, you might be able to see it as a colloid or suspension, where you can see particles suspended in another.
Can water be a substance mixture and solution?
Water is a physical object and is therefore a substance. Pure water, however, is not a solution or a mixture. Water with dissolved solutes would be a solution and mixture.
