Answer:
Earth and its atmosphere are continuously altered. Plate tectonics shift the continents, raise mountains and move the ocean floor while processes not fully understood alter the climate
Explanation:
The attractive forces between the neighboring particles of a substance are known as intermolecular forces. The state of a substance relies upon the strength of the intermolecular forces among the molecules in a substance.
There are three kinds of intermolecular forces, that is, the dipole-dipole forces, ion-dipole forces, and the London dispersion forces. On the basis of the kinds of intermolecular forces, it is concluded that the intermolecular forces primarily relies upon the nature of the molecule's bonding.
Thus, on the basis of the nature of bonding between the associating atoms in a molecule one can know about the nature of intermolecular forces. On the basis of Newton's law of gravitation, all the physical bodies get fascinated towards each other, and it is known that each physical body comprises of matter. Thus, the matter is fundamentally attracted by other matter.
Answer:
Environment refers to everything that surrounds an individual and interacts between them. The factors that control the environment can be biotic and abiotic.
Humans have greatly affected the environment. Some of the ways in which the environment is affected by humans are as follows-
(1) Humans have constructed industries and factories that have released a huge amount of toxic gases into the atmosphere.
(2) These harmful gases have increased the earth's global temperature. As a result of which the global warming effect has increased.
(3) The waste materials eliminated from these industries mix with the rivers and streams and pollute the water. It degrades water quality.
(4) The fossil fuels are exhausted at a very high rate.
(5) The spilling of the oils in the oceans has affected the marine species drastically.
(6) Due to the extensive mining at different places, soil fertility has decreased considerably.
(7) Cutting down trees for settlement purposes and other infrastructures.
The answer is c. because you have to increase concentration of h2
1 carot = 0.2 grams
1.5 carot = 0.3 grams.
1 mol of Carbon = 12 grams
x mol = 0.3 grams
0.3 * 1 = 12 x
x = 0.3/12
x = 0.025 mol
1 mol of Carbon is 6.02 * 10^23 atoms
0.025 mol of carbon is x
1/0.025 = 6.02*10^23 * /x
x = 0.025 * 6.02 * 10^23
x = 1.5 * 10^22 atoms of carbon.
