Answer:
the anwser would be B obtain energy
Explanation:
Answer:
54
Explanation:
Given an atom of Tellurium;
Tellurium has an atomic number of 52;
Unknown:
The number of electrons in a -2 anion
Solution:
The atom is;
Te²⁻
A neutral tellurium atom has 52 electrons
When it forms an anion, it becomes negatively charged;
This implies that the number of electrons becomes more,
So, the number of electrons = 52 + 2 = 54
So, the electrons are 54
For the calculation of number of moles of HCl
that is produced by 2.73 moles of H₂.
Considering the reaction shown below:
H₂ + Cl₂------->2HCl
This can be seen from the reaction that 1 mole of H₂ produce=2 mole of HCl
So , 2.73 mole of H_{2} will produce= 2.73\times 2 mole of HCl
That is 2.73 mole of H_{2} will produce= 5.46 mole of HCl
So 5.46 mole of HCl will be produced by 2.73 mole of H_{2}
