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.
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.
One way to separate a marble and rice mixture is to use a sieve or mesh strainer. By pouring the mixture through the sieve, the rice will pass through while the marbles will be left behind. Another method is to use your hands to physically pick out the marbles from the mixture.
To separate a mixture of salt and rice, you can use the method of dissolving the salt in water. When you add water to the mixture, the salt will dissolve while the rice will remain intact. Then, you can filter the mixture to separate the rice from the salty water. Finally, you can evaporate the water to obtain the salt.

You could use a sieve or strainer to separate the rice from the dried soup mix. Just pour the mixture into the sieve and shake it gently to separate the two components.
Rice can be separated from water by using a strainer or a colander. Simply pour the rice and water mixture into the strainer, and the water will drain out, leaving the rice behind.
To separate a mixture of peas and rice, you can use a method based on size and density differences. First, spread the mixture on a flat surface and manually pick out the peas, as they are larger and can be easily distinguished from the rice. Alternatively, you can use a sieve or a colander with holes small enough to let the rice fall through while retaining the peas. This method efficiently separates the two components based on their physical characteristics.
Yes, rice grains and flour would form a heterogeneous mixture. In a heterogeneous mixture, the individual components remain distinct and can be visually identified. Rice grains and flour have different physical properties, such as size and texture, which prevent them from uniformly blending. Thus, you can see and separate the rice grains from the flour in the mixture.
Take a filter and filter it
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".
Simply dissolve in distilled water and filter out the salt solution. Now the residual thing is once again washed with distilled water and filtering. This process is repeated till the entire salt is removed right from rice. The advantage is that rice is insoluble in water
Add water to the mixture and stir well. Then strain out all the rice. After that, crystallize the water to take out the sugar... :)
No.
