The balanced equation is as follows:
Further Explanation:
The chemical reaction that contains equal number of atoms of the different elements in the reactant as well as in the product side is known as balanced chemical reaction. The chemical equation is required to be balanced to follow the Law of the conservation of mass.
Displacement reactions:
These reactions are also known as replacement or metathesis reactions. These types of reactions occur when one of the reactant is replaced by the other one. Usually the more reactive element displaces the less reactive element. Both metals and non-metals can take part in displacement reactions.
Such reactions are generally expressed as follows:
Examples of displacement reactions are as follows:
(a) The reaction between copper metal and silver nitrate to form silver metal and copper nitrate as:
(b) The reaction between chlorine gas and potassium bromide to form potassium chloride and bromine gas as:
The steps to balance a chemical reaction are as follows:
Step1: Complete the reaction and write the unbalanced symbol equation.
In the displacement reaction, sodium acetate reacts with hydrochloric acid to form NaCl and . The physical state of , HCl, NaCl and is aqueous. The unbalanced chemical equation is as follows:
Step2: Then we write the number of atoms of all the different elements that are present in a chemical reaction in the reactant side and product side separately.
• On reactant side,
Number of sodium atom is 1.
Number of carbon atoms is 2.
Number of oxygen atoms is 2.
Number of hydrogen atom is 4
Number of chlorine atoms is 1.
• On product side,
Number of sodium atom is 1.
Number of carbon atoms is 2.
Number of oxygen atoms is 2.
Number of hydrogen atom is 4.
Number of chlorine atoms is 1.
Step3: Initially, we try to balance the number of other atoms of elements except for carbon, oxygen, and hydrogen by multiplying with some number on any side.
Sodium and chlorine atoms are balanced on both sides. Now the reaction is,
Step 4: After this, we balance the number of atoms of carbon and then hydrogen atom followed by oxygen atoms.
Carbon, hydrogen, and oxygen atoms are balanced on both sides. Now the reaction is,
Step5: Finally, we check the number of atoms of each element on both the sides. If the number is same then the chemical equation is balanced.
The balanced chemical equation is as follows:

The particle that makes the atom an unstable isotope is either excess proton or excess neutron.
Unstable isotopes are isotopes of an element that have an excess of either protons or neutrons in their atomic nucleus, making them prone to undergo radioactive decay.
Radioactive decay is the process by which an unstable atomic nucleus releases energy in the form of radiation to achieve a more stable configuration.
The specific particles that can make an atom an unstable isotope are:
Protons: If an atom has an excessive number of protons in its nucleus, it can become unstable.
Neutrons: Similarly, if an atom has an excessive number of neutrons in its nucleus, it can become unstable.
Thus, the particle that makes the atom an unstable isotope is either excess proton or excess neutron.

Answer:
Explanation:
H⁺ = 1.2 x 10⁻²
pH = - log[H⁺]
= - log [ 1.2 x 10⁻²]
= - log1.2 + 2
= - .079 + 2
= 1.921 .
B) BaI2
C) PCl3
D) CS2
Which of the following shows the equation balanced?
A. 3 O2 + CS2 → CO2 + 2 SO2
B. 3 O2 + CS2 → 2 CO2 + SO2
C. O2 + CS2 → CO2 + SO2
D. 4 O2 + 4 CS2 → 4 CO2 + 4 SO2
Answer:

Explanation:
The equation balanced is:
→
This can be proved with the amount of atoms of each element in reagents and products:
Reagents:
O=6
C=1
S=2
Products:
O=6
C=1
S=2
The option that shows the that the equation is balanced is:
3O₂ + CS₂ → CO₂ + 2SO₂ (option A)
The equation O₂ + CS₂ → CO₂ + SO₂ can be balanced as shown below:
O₂ + CS₂ → CO₂ + SO₂
There are 2 atoms of S on the left side and 1 atom on the right. It can be balanced by writing 2 before SO₂ as shown below:
O₂ + CS₂ → CO₂ + 2SO₂
There are 2 atoms of O on the left side and a total of 6 atoms on the right. It can be balanced by writing 3 before as shown below:
3O₂ + CS₂ → CO₂ + 2SO₂
Now, we can see that the equation is balanced. Thus, the correct answer to the question is 3O₂ + CS₂ → CO₂ + 2SO₂ (option A)

B) Mg with 14 neutrons
C) Fe with 26 neutrons
D) Ti with 26 neutrons
The correct answer is option B: Mg with 14 neutrons
The mass spectrum shows the charge to mass ratio of atoms. I can be used to sort the isotopes of an element.
Isotopy is a phenomenon in which atoms of the same element have the same atomic number but different mass numbers.
The mass spectrum of atoms separates atoms on the basis of charge to mass ratio of the isotopes.
The isotopes of magnesium are; 24Mg atom which has 12 neutrons 25Mg which has 13 neutrons, and 26Mg which has 14 neutrons.
Hence, the peak at 26amu represents 26Mg which has 14 neutrons.
Answer:
The answer is B
