Answer:
2,0 M of Al³⁺ and 6,0M of NO₃⁻.
Explanation:
In water, Al(NO₃)₃ dissociates as follows:
Al(NO₃)₃ → Al³⁺ + 3 NO₃⁻
That means in water, you will have 1 mole of Al³⁺ and 3 moles of NO₃⁻ per mole of Al(NO₃)₃.
Now, as the solution of Al(NO₃)₃ is 2,0M, you will have
<em>2,0 M of Al³⁺ and 6,0M of NO₃⁻.</em>

these are are metals having a high density
Explanation:
Helium is created from hydrogen in the Sun's core. Nuclear fusion is the term for this. Each helium atom is created by the fusion of four hydrogen atoms.
<h3>How did the Sun's nuclear fusion process begin?</h3>
The proton-proton chain describes how fusion occurs in the Sun. Protons are the starting point, and the Sun transforms them into helium through a process. This fusion produces energy because the energy of the protons that went into the helium is less than the energy of the helium itself.
<h3>How does the Sun produce energy through nuclear fusion?</h3>
Nuclear fusion is the method through which the sun produces energy inside of its core. The sun's intensely high pressure and heat during nuclear fusion lead hydrogen atoms to split apart and their nuclei—the atoms' central cores—to fuse or merge.

elements have equal number of protons and neutrons
the condensed format is when the closest noble gas with the closest electron configuration is given, this closest noble gas atomic number should be lesser than the atoms atomic number
atomic number of Kr is 36
1 electron in 5s subshell and 7 electrons in 4d subshell.
there's a total of 36 + 1 + 7 = 44 electrons
atomic number of the atom is 44
element with atomic number 44 is Ruthenium - Ru
answer is Ru
