A closed system is a system in which matter is prevented from being removed or brought in. Biosphere 2 provides us with an example of a closed system. This is because it was specifically designed to remain isolated from external materials in order to maintain a completely separate environment inside.

Can hydrogen Bonds form among hydrogen chloride molecules? Why?​
Kay [80]

Explanation:

<h3>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.</h3>

Who is normally welcome in North Korea?
8_murik_8 [283]
Hello!

Normally South Koreans are not welcome or permitted to visit North Korea, at any time of the year. This is most likely because of the past conflict between the two countries. Otherwise I believe anyone should be eligible to visit North Korea without much hassle. Although, many people say that it is unsafe to visit the country because of their nuclear weapons, but who knows?

I hope that answers your question!
