gayaneshka [121]

Answer:

1.53x10^22 atoms of Au

Explanation:

To find the atoms of gold we need first, to convert the mass of gold to moles using molar mass of gold (196.97g/mol). Then, these moles must be converted to number of atoms based on definition of moles (1 mole = 6.022x10²³ atoms).

<em>Moles Au:</em>

5.00g Au * (1mol / 196.97g) = 0.0254 moles of Au

<em>Atoms of Au:</em>

0.0254 moles * (6.022x10²³ atoms / 1 mole) =

Hat is used and produced in glycoloysis?
agasfer [191]

During glycolysis is used glucose, ADP and pyruvate and produce ATP, water and NADH.

<h3>What is glycolysis?</h3>

Glycolysis is the first step of cellular respiration by which glucose is used to generate energy in the form of ATP.

Cellular respiration has three sequential steps, i.e., glycolysis, the Krebs cycle and oxidative phosphorylation.

Glycolysis is the cellular respiration step that generates 2 net high energy ATP molecules and 2 reduced NADH.

In conclusion, glycolysis uses glucose, pyruvate and ADP to generate ATP, water and Nicotinamide adenine dinucleotides (NADH).
