Answer:

Robert Louis Stevenson, in full Robert Louis Balfour Stevenson, (born November 13, 1850, Edinburgh, Scotland—died December 3, 1894, Vailima, Samoa), Scottish essayist, poet, and author of fiction and travel books, best known for his novels Treasure Island (1881), Kidnapped (1886), Strange Case of Dr. Jekyll and Mr. Hyde (1886), and The Master of Ballantrae (1889).

The Stevenson screen ​is painted white to refract the sun's rays more effectively.

What is Stevenson screen?

Stevenson's screens are indeed painted white to refract the sun's rays more effectively. The skylights sides allow air to circulate around the thermometers. A psychrometer generator that pushes external air across the equipment inside helps the airflow in some places.

Its goal is to offer a consistent environment for measuring temperature, humidity, dew point, and atmospheric pressure.

A Stevenson screen's aim is to protect thermometers against precipitation and direct sunlight from outside sources, while enabling air to move freely around them. As a result, the screen provides a virtually unified enclosure that is the same temperatures as the air outside.

Can hydrogen Bonds form among hydrogen chloride molecules? Why?​

Answers

Explanation:

Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.The hydrogen bond does not form because the chlorine atom is too large. Despite chlorine's high electronegativity its big size lowers the negative charge density and it is not enough to attract a hydrogen atom in a stable phase. Nevertheless, there is a small dipole-dipole attraction between adjacent HCL molecules.

please help me to solve this question help me faster please ​

Answers

Answer:

1. [tex]p = \frac{m}{v}[/tex]

2. The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).

3.

m = 43.5 g

V = 50 mL

d = 43.5 g / 50 mL = 0.87 g/mL

Density of this cooking oil is 0.87 g/mL.
