"Balancing by inspection," often known as trial and error, is the most fundamental and widely used technique for balancing chemical equations. Several strategies can be employed to lessen the number of tries and errors necessary to generate an equation that is ultimately suitably balanced. The conservation of matter criterion must be followed in order for a chemical equation to be considered balanced. There are two different kinds of numbers that are employed in chemical equations. In the chemical formulations of the reactants and products, subscripts are employed. Additionally, coefficients are used to show how many molecules of a certain substance are used up or produced before chemical compositions.

(D) n–pentane C5H12
The boiling point of n-heptane is 98.42°C. And it has 7 Carbon atoms. Therefore, option (B) is correct. It has the highest boiling point among all the given compound.
When carbon chain gets longer, there are more and more electrons in a molecule. Which means that there are more stronger intermolecular forces between the molecules as alkali chain increases. As a result, it will take more energy to break these forces. Therefore, the melting or boiling points increase as we go from lower to higher straight alkali chain. Thus the chain with more number of carbon atom will have highest boiling point. n-heptane will be the answer.
The boiling point of n-butane is -1°C.
The boiling point of n-pentane is 36.1 °C.
The boiling point of n-hexane is 69°C.
The boiling point of n-heptane is 98.42°C.

Does hydrogen need a full octet?.
Both helium and hydrogen do not adhere to the octet rule and require two electrons in the valence shell in order to be stable. They just need to occupy the s² orbital since they lack p-orbitals.
The main-group elements have the propensity to connect in such a way that each atom has eight electrons in its valence shell, giving it the same electronic structure as a noble gas. This is reflected in the theory behind the octet rule, a chemical rule of thumb. Although the rule is more broadly applicable to the s-block and p-block of the periodic table, it is most relevant to carbon, nitrogen, oxygen, and halogens. There are other laws, such as the duplet rule for hydrogen and helium or the 18-electron rule for transition metals, that apply to different elements.

True. Calcium ion determines the muscle contraction in the sarcoplasm. sliding stops with the decrease of the calcium ion in the sarcoplasm.
Sliding filament theory explains the the increase in the calcium ion levels in the sarcoplasm starts the sliding of the thin filament. In muscle contraction myosin binds to actin. The increase in calcium ion levels in the sarcoplasm initiates the sliding of filaments. When an action potential arrives, calcium ions are released from the sarcoplasmic reticulum into the sarcoplasm around the thick and thin filaments. The calcium ions then bind with troponin which causes a change in the shape of the troponin molecule. Since troponin is bound to tropomyosin, this causes a shift in the position of tropomyosin. The myosin-binding sites on actin which are normally covered by tropomyosin. They are now exposed. Now, the myosin heads can bind actin, initiating the sliding of the filaments.

Lone pairs, also known as unshared pairs or non-bonding pairs, are valence electron pairs in chemistry that are not shared with another atom in a covalent bond. Atoms outermost electron shell is where lone pairs are located. By employing a Lewis structure, they may be located. If two electrons are paired but aren't utilised in chemical bonding, they are consequently referred to as lone pairs.
