The stability of atomic nuclei relies on the forces within the atom that balance out the charge. The electrons have the power to make an atom negatively or positively charged, but neutrons allow the atom to be electrically neutral regardless. The gravitational pull of protons and neutrons in the atomic nuclei keeps the electrons in an orbit, and with less protons than neutrons, electrons will be pulled into the nuclei and make the atom unstable; with less neutrons than protons, the electrons will be repelled and make the atom unstable. Therefore, the number and ratio of protons to neutrons are the factors that make an atom stable.

Answer: ratio of neutrons to protons and number of protons and neutrons

Hope this helps!

<h2>Answer : Option B) Ratio of neutrons to protons.</h2><h3>Explanation :</h3>

The stability of the atomic nuclei is related to the ratio of neutrons and protons in the nucleus.

As the atomic stability mainly is determined by the ratio of the neutron and protons and also by the total number of nucleons present in the nucleus.

A hydrocarbon molecule has seven carbon
Damm [24]

Answer: Option (3) is the correct answer.

Explanation:

When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.

When  a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.

When  a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.

Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.

Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide: CaO (s) + H2O (l) → Ca(OH)2 (s) In a p
dybincka [34]

Answer:

The option closest to the percentage yield is option;

d. 81.1

Explanation:

The given chemical equation of the reaction is presented as follows;

CaO (s) + H₂O (l) → Ca(OH)₂

The mass of CaO in the experiment, m = 2.00 g

The volume of water with which the CaO was reacted = Excess volume of water

Number of moles = Mass/(Molar mass)

The mass of Ca(OH)₂ recovered, actual yield = 2.14 g

The molar mass of CaO = 56.0774 g/mol

The number of moles of CaO in the reaction, n₁ = 2.00 g/(56.0774 g/mol ≈ 0.036 moles

The molar mass of Ca(OH)₂ = 74.093 g/mol

The number of moles of Ca(OH)₂ in the reaction, n₂ = 2.14 g/(74.093 g/mol) ≈ 0.029 moles

From the given chemical reaction, one mole of CaO reacts with one mole of H₂O to produce one mole of Ca(OH)₂

Therefore, 0.036 moles of CaO will produce 0.036 moles of Ca(OH)₂

Mass = Number of moles × Molar mass

The mass of 0.036 moles of Ca(OH)₂ ≈ 0.036 moles × 74.093 g/mol = 2.667348 grams

∴ The theoretical yield of Ca(OH)₂ = 2.667348 grams

Percentage \ yield = \dfrac{Actual \ yield}{Theoretical \ yield}  \times 100 \%

The percentage yield = (2.14 g)/(2.667348 grams) × 100 = 80.23%

Therefore, the option which is closest is option d. 81.1.
