Answer:did u ever get the answer
Explanation:i have a homework to do
Yes you are right .. X is undergoing a change from solid to gas at point E
Answer is: Fluorine and chlorine, because they are both halogens.
Halogen elements are in group 17: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.
In the gaseous state halogens form diatomic covalent molecules.
Halogen diatomic molecules (halogen means "salt producing") in the gaseous state in room temperature are fluorine (F₂) and chlorine (Cl₂).
Both molecules have single covalent bond and they are very reactive.
Halogens need to gain one electron to have electron cofiguration like next to it noble gas. For example, fluorine has 9 electrons and it gain easily one electron in chemical reaction to have electron configuration like noble gas neon (Ne) with 10 electrons.
That is a hypothesis an educated guess of what will happen
The length is 1.36 feet and the breadth is 17.647 feet of the plate, if friction drag is 0.3 lbf.
T = 20°C = 293 K
P = 1 atm = 101.325kP
P = ρRT
ρ = 1.205 kg/m³
Total drag = C∝ * (1/2 .ρ . A . V²)
0.3 lbf = C∝ * 1/2 * 1.205 * 4.645 * (15.24)²
C∝ = 2.05338 * 10 ⁻³
Now,
C∝ = 1.328 / √Re
2.05338 * 10 ⁻³ = 1.328 / √Re
∴ Re = 418267.61
∴ ρ. v. l/μ = 418267.61
1.205 * 15.24 *L/18.207 * 10⁻⁶ = 418267.61
Length = 0.4147 m = 1.36 foot
L * B = 24 ft²
1.36 * B = 24
∴ breadth = 17.647
Hence, Length is 1.36 feet and the breadth is 17.647 foot.
