The question is incomplete, the complete question is :
Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of 
kg and the mass of bacterium is on order of 
kg
Answer:
The total numbers of atom in bacterium are 
.
Explanation:
Mass of hydrogen atom, m= 
kg
Mass of bacterium , M= kg
Mass of bacterium atom =m'
Given ; 
let the number of atoms in bacterium be N
The total numbers of atom in bacterium are .
Answer:
electrons are fermions, they can only access an energy level if it has not already been occupied by another electron. Thanks to this principle, there is a minimum energy level within the atom and it is not possible for an electron to collapse to the nucleus because it cannot exceed this} threshold.

Answer:
Arranged in order of most soluble to least soluble in water:
Explanation:
Water is a polar solvent due to the electric charge it possesses. Hence it would only dissolve polar molecules.
Non-polar molecules would be dissolved by non-polar solvents.
Short chain alcohols are more soluble than butanol, but generally the polar -OH group is soluble in water.
I think you want to ask the complete ionic equation and net ionic equation. For complete ionic equation: 3Ba2+ + 6Cl- + 2Al3+ + 3SO42- -->3BaSO4 + 2Al3+ + 6Cl-. For net ionic equation: 3Ba2+ + 3SO42- -->3BaSO4.
<span> aluminum is an element. All elements are pure substances, so that means they are homogenous.
