Chemistry
1 answer:
solmaris [256]3 years ago
4 0

Answer:

              8.87 × 10⁻⁷ grams

Explanation:

Moles = No. of Particles / 6.022 × 10²³ Particles/mol

Moles = 4.95 × 10¹⁵ atoms / 6.022 × 10²³ atoms/mol

Moles = 8.22 × 10⁻⁹ mol

Also,

Mass = Moles × M.Mass

Mass = 8.22 × 10⁻⁹ mol × 107.87 g/mol

Mass = 8.87 × 10⁻⁷ grams

fiasKO [112]

Answer:

True

Explanation:

US. With an installed capacity of 3,639MW in 2018, the US is the leading producer of geothermal energy across the world, producing 16.7 billion kilowatt hours (kWh) of geothermal energy throughout the year. More recently, extensive direct heat utilization projects have been undertaken in many European countries, and electric power developed extensively in Italy and Iceland. Geothermal heat pumps became extensively used in Austria, Switzerland, Germany and Sweden (Antice, Miklos and Sanner, Burkhard, 2007).

The bond that join the 3'-hydroxyl group of the deoxypentose of one nucleotide to the 5'-hydroxyl group of the deoxypentose of a
lara [203]

Answer:

phosphodiester bond

Explanation:

<em>Phosphodiester linkage/bond is found in deoxyribonucleic and ribonucleic acids. It is formed from a reaction involving the elimination of water from a reaction involving the hydroxyl groups of two different 5-carbon (pentose) sugars and a phosphate group.</em>

The elimination of water, also known as condensation reaction occur twice, resulting in the formation of two ester bonds which then bind the phosphate group to the pentose sugars to become a phosphodiester bond.

The bond links the 3'-hydroxyl group of one of the pentose sugars and the 5'-hydroxyl group of the other pentose sugar in the nucleotides that make up nucleic acids.
