Distilled water is usually a pure substance. Occasionally it contains a very small amount of chloride ions, and then it is an homogeneous mixture.
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
River water is generally a heterogeneous mixture based on the different components it is carrying. Water by definition is not an element, rather a molecule comprised of them.

To separate the mixture of chalk powder, water, and stones, you can use a process called sedimentation followed by filtration. Allow the mixture to settle, as the stones will settle at the bottom due to their higher density. Then, carefully pour off the water to a separate container, leaving the stones behind. Finally, filter the remaining mixture to separate the chalk powder from the water.
A mixture of sand, lime, and water, used as a lubricant to help move stones, is mortar. Mortar. slick. Mortar.
Such a mixture is known as mortar
Use a sieve to remove the paper clips and small stones. Heat the remaining solution until the water evaporates (which is recovered by condensation). This will leave the salt behind.
You would not add sand to a mixture intended as a lubricant.

One way to separate small stones from dirt is to use a sieve or mesh screen. Pour the mixture of dirt and stones onto the sieve and shake it gently so that the dirt falls through the holes while the stones are left on top. Another method is to handpick the stones out of the dirt.
You can filter the water through a sieve or cloth to separate the stones and small particles from the water. Another option is to let the water settle in a container, then carefully pour off the cleaner water, leaving the sediment at the bottom.
You could pick the stones out of the mixture. You could you use water to rinse ash off individual stones and then let the rinsed ashes dry.
One way to separate big stones from little stones is to use a sieve or mesh screen with appropriately sized holes. Pour the mixture of stones onto the sieve and shake it gently to allow the small stones to fall through while retaining the big stones on top.
One way to separate stones from grains is by using a sieve or a mesh screen. Pour the mixture of stones and grains over the sieve and shake it gently. The grains will pass through the small holes while the stones remain on top of the sieve.
