Coal and soil are heterogeneous mixtures and they cannot be classified as solutions.

Which variety of coal is a heterogeneous mixture?

Peat is a heterogeneous mixture of more or less decomposed plant material that is accumulated in water, in the absence of air (anaerobic conditions). Peat is the primitive form of coal. The carbon content of peat is least when compared to lignite, bituminous, or anthracite coal.

Is charcoal and water a homogeneous mixture?

Textbook solution The salt solution, alcohol and water, air dissolved in water, air, seawater, fruit juice, and brass are a homogeneous mixture. All the mixtures cannot be seen separately. Petrol and water, sand and charcoal, and mist are heterogeneous mixtures.

Is coal a compound of element?

-Coal is made up of more than one compound so it is a mixture. -Oxygen is a single atom (O) so it is an element. -Alcohol is made up of carbon, hydrogen, and oxygen so it is a compound.

Is coal an element?

Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Why is coal not a solution?

Meanwhile, the coal industry argues that it plays an indispensable role in tackling ‘energy poverty’ – that is, the lack of access to modern non-polluting forms of power, primarily electricity. But coal is not the solution. Just the health consequences of coal production and combustion are staggering.

Which of the following coal is superior?

Anthracite
Complete answer: So, the superior quality coal is called Anthracite. Anthracite, additionally referred to as anthracite coal, is a hard, compact variety of coal that includes a sub metallic luster.

Which of the coal has highest of mixture?

Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter. Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite.

Which type of mixture is Sand and charcoal?

Heterogeneous mixture: Sand and charcoal, air, fruit juice, mist, petrol and water.
