Explanation:
An element is a pure substance such as gold and silver. You can find those elements in the periodic table. A compound is a substance consisted of molecules from two or more different elements. Water is made up of hydrogen and oxygen (H2O). Sugar is a very wide category of compounds. Carbon dioxide is made up of carbon and oxygen (CO2). Ice is frozen water/water in the solid state (H2O). A mixture is a group of substances held together physically. Seawater is a mixture of water and salt. A chocolate sundae is a mixture of chocolate sauce and ice cream. Air is a mixture of many gases including oxygen and nitrogen. A big mac is a mixture of burger meat, lettuce, tomatoes, etc.
Answer:
sugars such as dextrose and sucrose increase the surface tension of water. The effect was interpreted as a depletion of the solute molecules from the water-air interface.
Answer: C
Explanation:
Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.
