If we're talking about normal rice-sized rice and standard glass marbles, it's not much of a problem; it would be like separating horses from cats. So let's suppose the "marbles" are chips of metamorphic limestone, cunningly carved to resemble grains of rice.
1. Since rice is less dense that marble, we could irrigate (flush with water) the rice-marble mixture. At some velocity, the rice would be washed away while the marble would remain.
2. We could just a stream of air the same way.
3. We could expose the mixture to a colony of ants, who would carry away the rice and leave the marble.
You could use the scientific way and do filteration with filteration or a seive ????
I PUT WOOD CHIPS AND MARBLE IN THE WATER the wood chips going up and marble stays down
In a beaker put in some marbles and 20ml of water.Using a filter funnel and filter paper let the water soak through the filter paper.
A sieve of the proper size will do it. As this is a mixture of the rice and salt, we should be able to separate them by mechanical means. Pour the stuff into the sieve, and bump it gently with the palm of the hand until all the salt falls through. That should leave the rice caught in the net.
Things that can be separated by physical means are mixtures. There are two types of mixtures: homogeneous and heterogeneous. In a heterogeneous mixture, you can see the different components that make up the mixture. You can't see the components in a homogeneous mixture. Things that can only be separated by chemical means are compounds.
No, 1 litre container can hold about 11,000 grains of rice (if cooked!) You could fit about 50,000 uncooked grains in a litre container
One grain of rice is called a grain of rice. The plural form is grains of rice.

Water.
That depends on the interpretation of homogeneous and at what level you look at the statement/the rice. Can you have a mixture of just one thing? How many separate components are there in reality - water, salt, starch, protein, etc etc. etc., plus the air between the grains. I would argue that it is homogeneous as to me the word means uniform throughout, but I'd drop the word "mixture".
?
No.
Add water to the mixture and stir well. Then strain out all the rice. After that, crystallize the water to take out the sugar... :)

You can do this with a sieve. Simply pour the mixture into a sieve, the water will drain through the tiny holes, whereas the rice will stay in the sieve because it is too large to go through the tiny holes.
Mixture
Filteration
Neither; rice is a mixture of many compounds.
dissolve the sugar into water then filter the rice out and boil the water off
