The hybridization for C in acetylene, HCCH, or C₂H₂ is 'sp'.
Discussion:
There are three different forms of hybridization -
- sp- The first occurs when two carbon atoms are triple linked.
- sp₂- When two carbon atoms are double-bonded to one another, this is known as sp₂.
- sp₃- When a single bond joins two carbon atoms, this is known as sp₃.
In the case of acetylene(HCCH or C₂H₂):
- The carbon atom requires additional electrons to establish four bonds with hydrogen and other carbon atoms in the synthesis of C₂H₂. One 2s₂ pair is consequently transferred to the vacant 2pz orbital. Each carbon has two sp hybrid orbitals after the 2s orbital in each atom combines with one of the 2p orbitals.
- As a result of the atoms' symmetrical alignment in a single plane, C₂H₂ possesses a linear molecular structure. Due to their lower electronegative nature than Hydrogen atoms, all Carbon atoms are situated near the center of the Lewis structure of C₂H₂.
H-C≡C-H
Therefore, it is concluded from the above discussion that the hybridization type of acetylene is 'sp'.

The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency.<span> Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.</span>
Answer:
A
Explanation:
Ductility, because it can be observed by altering the shape of the substance
Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.

Answer:
molar mass CO = 28.01 g/mol
3.45 x 10^2 x 28.01 =9.66 x 10^3 g
mass Zn = 2.45 x 10^-2 x 65.39 g/mol=1.60 g => 1.60 x 10^0
