Answer:
6.022×1023 particles are present in one mole of a substance while about 7.5 x 1018 grains of sand are present on earth's beaches.
Explanation:
Mole is used in chemistry for the calculation of mass of an atom. 6.022×1023 particles are present in one mole of a substance while about 7.5 x 1018 grains of sand are present on earth's beaches. According to this data which shows that the size of mole is greater than the number of sand grains present on Earth’s beaches because there are higher particles are present in mole as compared to sand grains. So the mole has big size.
Coffee is a mixture because it is a mixture of many compounds
<h2>Answer:</h2>
D) The geosphere, hydrosphere, and atmosphere
<h2>Explanation:</h2>
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
