Answer: C3H4 (Propayne) have a triple bond.
Explanation:
The hydrocarbons which having triple bond are called alkyne. The general formula of alkyne is CnH2n-2. Here, n is number of carbon atoms.
In alkyne, the number of hydrogen atom is 2 less than double the number of carbon atoms.
Thus, the compound C3H4 (Propyne) have a triple bond.
The energy levels of an atom are occupied by electrons. These energy levels are often represented as shells, and each level can hold a specific number of electrons. Electrons are crucial in determining an atom's properties.
The energy levels of an atom are occupied by electrons. An atom's structure consists of a nucleus, which is surrounded by the energy levels. These energy levels, often represented as shells, house the electrons. For example, the first energy level can accommodate up to 2 electrons, while the second energy level can hold up to 8. These electrons play a critical role in determining the physical and chemical properties of atoms and subsequently, the substances they form.

you are welcome for that
Answer:you need to write the equation of the reactions in each question.
you need to calculate the mol for each substance which mass for which mass is given
then you do mol ratio.
I hope this shows you a hint and helps you not to depend completely on brainly.
plz put me as Brainliest
