Students are investigating the differences in open and closed systems. They heated 2 containers of water. They recorded their re

sults in the tables shown.
Two tables.Short description, Two tables.,Long description,
Container 1
Before After Mass of Container and Contents in grams 200 150 Volume of Water in milliliters 100 50
Container 2
Before After Mass of Container and Contents in grams 200 200 Volume of Water in milliliters 100 50
Question
What can the students conclude from the results of their investigation?
Answer options with 4 options
A.
Container 1 is a closed system because a gas was produced. Gases do not have mass.
B.
Container 1 is an open system because a gas was produced. Gases make things lighter.
C.
Container 2 is an open system because the volume changed even though the mass did not change.
D.
Container 2 is a closed system because the mass did not change even though the volume changed.

Container 2 is a closed system because the mass did not change even

though the volume changed.

<h3>What is a Closed system?</h3>

A closed system is the type of system which prohibits the transfer of

matter in and out the system.

In a closed system , the mass of the matter present is always the same

regardless of the changes which occurred which is why option D is the

most appropriate option.

What is the formal charge of nitrogen in no2cl
Gre4nikov [31]

Answer:

The formal charge on nitrogen in NO_{2}Cl is +1.

Explanation:

The structure of NO_{2}Cl is as follows.

(In attachment)

Formal\, charge = Valence\, electron - (nonbonding\, electrons + \frac{Bonding\,electrons}{2})

From the structure, Nitrogen has no non bonding electrons. Nitrogen has four bonds and each bond corresponds to 2 electrons. Hence, nitrogen have eight bonding electrons and five valence electrons.

Formal\,charge\,on\,nitrogen = 5-[0+ \frac{8}{2}]= +1

Therefore, The formal charge on nitrogen in NO_{2}Cl is +1.

Calculate the oxidation numbers of the elements in this equation<br> 2 Al2O3 → 4 Al + 3 O2
riadik2000 [5.3K]

Explanation:

Answer

Open in answr app

The rule used here is that the algebraic sum of the oxidation numbers of all the atoms a molecule is zero.

Al2O32× ( oxidation number of Al)+3× ( Oxidation number of O )  = 0

2× ( Oxidation number of Al) +3(−2)=0

2× ( oxidation number of Al) +6

∴ Oxidation number of Al =+3

4. What are the characteristics of<br> the particles of matter?
mojhsa [17]

Not sure how in depth or what level of particles but I will go as deep as I know. The matter that makes up the world is comprised of 12 particles which are known as fermions. There are 12 fermions which are made up of 6 quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Technically, only the up quark, down quark, electron, and electron neutrino are necessary to create all known matter since others would simply be very unstable and decay into those particles. The other type of particles are known as Bosons. These particles transmit forces and all sorts of different interactions. I have included a photo from online which describes the main characteristics of each elementary particle.
