We can conclude that each carbon atom in acetylene shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.
A chemical bond is a long-lasting attraction between atoms or ions that allows molecules and crystals to form. Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.
Each carbon atom in acetylene shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.
The carbon atom contains four electrons. It requires four electrons to become stable in its outermost shell. Two carbon atoms covalently bond three pairs of electrons with each other in acetylene, and the remaining pair covalently bonds with two hydrogen atoms.
As a result of the carbon and hydrogen atoms becoming more stable, we can conclude that in acetylene, each carbon atom shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.

Red giant would be the answer here
Answer:
It will sink
Explanation:
The density of the water is 1 g/cm³
- Elements having less density than water will float
- Elements having more density than water will sink
We are given that the density of density of aluminum is 2.7 g/cm³ which is more than the density of the water.
Therefore, it will sink.
Hope this helps :)
This is because solids have less energy than liquids do, hence it takes more energy to excite a solid into its gaseous phase than it does a liquid.
When opposed to merely reducing their separation, from solid to liquid, the energy needed to totally separate the molecules as they move from liquid to gas is substantially higher. The latent heat of vaporization is therefore bigger than the latent heat of fusion for this reason.
<h3>
What is heat of sublimation?</h3>
The amount of energy required to change one mole of a substance from its solid to its gaseous state under particular conditions—typically the standard ones—is known as the enthalpy of sublimation or heat of sublimation (STP). A solid's worth is based on its cohesive energy.
<h3>
What is heat of vaporization?</h3>
The term "enthalpy of vaporization," which is often referred to as "heat of vaporization" or "heat of evaporation," refers to the amount of energy that must be applied to a liquid substance in order to cause a part of that substance to transform into a gas. Vaporization's enthalpy varies with the pressure at which the transition takes place.

The correct question is:
Why heat of the sublimation of a substance is greater than the heat of vaporization?
