Answer:
3.29 × 10²⁸ Atoms
Solution:
Moles and Number of atoms are related to each other as,
Moles = Number of Atoms / 6.022 × 10²³ ------- (1)
Data Given;
Moles = 5.472 ×10⁴
Number of Atoms = ?
Solving eq. 1 for Number of Atoms,
Number of Atoms = Moles × 6.022 × 10²³
Putting values,
Number of Atoms = 5.472 ×10⁴ mol × 6.022 × 10²³ atoms.mol⁻¹
Number of Atoms = 3.29 × 10²⁸ Atoms
Answer:
Option B. At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent.
C. At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules.
Explanation:
Answer:
Oxygen, it's supposed to have six valenge electrons.
Explanation:
Count the dots on the oxygen atom, you'll see seven, but there's supposed to be six.
Answer:
Carbon dioxide levels in the Earth's atmosphere have been steadily increasing.
Carbon has a longer average lifetime in the atmosphere.
Explanation:
Today the level of carbon dioxide is higher than at any time in human history. Scientists widely agree that Earth’s average surface temperature has already increased by about 2 F (1 C) since the 1880s, and that human-caused increases in carbon dioxide and other heat-trapping gases are extremely likely to be responsible.
The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere. Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years.
