Balanced chemical reaction of hydrochloric acid and barium sulfite:
2HCl(aq) + BaSO₃(s) → BaCl₂(aq) + H₂O(l) + SO₂(g).
Balanced ionic reaction:
2H⁺(aq) + 2Cl⁻(aq) + BaSO₄(s) → Ba²⁺(aq) + 2Cl⁻(aq) + H₂O(l) + SO₂(g).
Net ionic reaction:
2H⁺(aq) + BaSO₄(s) → Ba²⁺(aq) + H₂O(l) + SO₂(g).
Isotopes are atomic elements with the same proton number. The atomic number of the Ru atom in the periodic table will be 44 and the mass will be 100.9.
<h3>What are atomic numbers and mass?</h3>
Atomic numbers are the number of protons present in the nucleus of the atom. Whereas the atomic mass is the total number of protons and the neutrons of the atom.
The atomic number is the number of protons and remains constant for the same element at different places or planets. Hence, the atomic number of Ruthenium will be 44.
The atomic mass depends on the relative abundance and is calculated as:
Therefore, the atomic mass of Ru is 100.9 and the atomic number is 44.

Answer:
The answer is covalent bond
Explanation:
when oxygen atom and two hydrogen atoms are combined, water molecule is formed according to the equation;
2H2 + O2 ==> 2H2O
Water is a covalent compound.
A covalent bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full outer shell, corresponding to a stable electronic configuration.
What happens in the artificial transmutation is that the nucleous is bombarded with high energy particles which we can describe as kinetic energy and the idea for them is to induce what we call transmutation. Also what happens is that the high energy particles are accelerated. One of the examples is when nitrogen is transformed into hydrogen by combining its nucleous with an alpha particle
Answer:
We get ammonia because the forward and reverse reactions are happening at the same rates.
If 3 mol of
H
2
is mixed in a sealed vessel with 1 mol
N
2
under suitable conditions then they will react to form ammonia
N
H
3
:
N
2
+
3
H
2
→
2
N
H
3
At the start of the reaction the concentration of the
N
2
and
H
2
are high. As soon as some
N
H
3
is formed the reverse reaction will start to occur:
2
N
H
3
→
N
2
+
3
H
2
The rate of the reaction depends on concentration so the forward reaction will be fast at first when the concentration of the reactants is high. It will slow down as their concentration decreases.
By the same reasoning the reverse reaction will be slow at first then increase. These two processes continue until a point is reached when the rates of the forward and reverse reactions are equal.
We now state that the reaction has reached equilibrium which we show by:
N
2
+
3
H
2
⇌
2
N
H
3
It is described as "dynamic" because the forward and reverse reactions are happening at the same time although the concentrations of all the species remain constant.
So although
N
H
3
is constantly breaking down, more is being formed at a constant rate.
In the Haber Process the system is actually not allowed to completely reach equilibrium as the process is continuous, as described in Mukhtar's answer.
