B. Copper since the rest of the choices are compounds. Copper is an element.
Exothermic. Exothermic exo meaning out, release heat while endothermic, endo as in in, take in heat.
Answer:
The solid particles will be trapped behind on the strainer while the liquid molecules will pass or filter through.
Explanation:
Filtration is a process of separation of mixtures involving an insoluble solid and a fluid such as liquids or gases using a filtering medium such as paper or cloth or any other material. During the process, the liquid molecules pass through the filtering medium whereas the solid particles are not allowed to pass through but are retained by the medium. The reason is that the pores on the filtering medium are only small enough for the liquid molecules to pass through but not the solid particles.
An example of a mixture that can be separated through filtration is a suspension of chalk and water. Also, a mixture of water and solid particles such as water and tea leaves can also be separated using a strainer with cloth.
In the question, if a mixture of insoluble solids in a liquid is passed through a strainer with cloth, the solid particles will be trapped behind on the strainer while the liquid molecules will pass through.
Answer:
Hi, the statements given in the question (a and b) are combination of right and wrong answers. But i will split the statement a and b into necessary fragments.
Carbohydrates are quick source of energy relatively. That is the only correct statement in the question.
Explanation:
Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen with the general formula (Cx H2y Oy) or Cx (H2O)y. They can be classified into simple sugar or complex sugar.
Simple sugars can be further divided into Monosaccharides (e.g glucose, fructose and galactose) and Disaccharides (e.g sucrose and maltose).
Complex sugar can be referred to as Polysaccharides (e.g cellulose and starch)
The statement above that says carbohydrate contains carbon, hydrogen and nitrogen polymers is not correct.
Carbohydrates are not mostly monosaccharides. They also contain Disaccharides and Polysaccharides.
They are not the only source of fuel.
