Hello!
To do this, use the molar mass. This is how much a mole of an atom weighs. A mole is 6.02214076×10²³ atoms.
Molar masses of:
Se: 78.96 g/mol
Cu: 63.546 g/mol
Ba: 137.327 g/mol
Now, the element with the highest molar mass will have the fewest atoms. This is because the element weighs more, so therefore for the same amount of mass, there will be less of the element needed to reach that mass.
Therefore, 10g of Ba would have the fewest number of atoms.
Hope this helps!
Answer:
Gibbs free energy equation
Explanation:
Answer: All cells need energy, which they get through ATP, an inherently unstable molecule that must continually be produced. Though ATP can be produced in different ways, nearly all living cells can harness ATP through glycolysis, the stepwise degradation of glucose, and other sugars, obtained from the breakdown of carbohydrates without the need for molecular oxygen (anaerobic). Glycolysis is an ancient, universal pathway that probably developed before there was sufficient oxygen in the atmosphere to sustain more effective methods of energy extraction.
