CS2 + 3O2 = CO2 + 2SO2

1 mole of CS2 gives 1 mole of CO2

12 + 2(32) = 76g of CS2  yields 44 g of CO2

Theoretically 1 g of CS2 yields 44/76 g CO2

Therefore 50 g CS2 should yield    50*44 / 76 = 28.95 g

So % yield = 103.6 %  ( which is not possible  because you can't create matter from nothing).

The 30g cannot be right . This is experimental err.

Which state of matter would be described as having highly energized, charged particles that move extremely fast
uranmaximum [27]
There are four states of matter, solid, liquid, gas and plasma. Their formation is as when solid is heated it converts into liquid, liquid on heating converts into gases and gases on heating converts into plasma.

Plasma:
           Plasma is the fourth state of matter. It is the highest energy state of matter.

Composition:
           Plasma is made up of negatively charged and positively charged particles.

Result:
           The answer to your question is Plasma.

What evidence is there that marker ink is a mixture
zheka24 [161]
Ink can be separated into black and other color pigments. This can be done on filter paper by dotting the marker just above the edge and adding ethyl alcohol, which drags the pigments separately across the paper.

1. Ionization energy is the energy needed to remove an electron from an atom. We can use the periodic table to predict ionizatio
just olya [345]

Ionization energy increases from left to right because the left wants to lose elctrons and the right wants to gain electron

As you go a group it is easier lose lose because the electrons are farther away from the nucleus and there is less attraction from the positive charges.

It should be 3p3. the p level can hold 6 electrons

Rubidium group 1, 1 valence electrons very reactive

Mg2,2 very reactive

Al 3, 3 reactive

How is it possible for two neutral objects to become charged by rubbing them together? A. The binding force of the objects’ atom
FinnZ [79.3K]

Answer:

D. The frictional force overcomes the force that binds the electrons to the atoms, enabling the electrons to move elsewhere

Explanation:

Neutral objects becomes charged by rubbing them together due to the frictional force which overcomes the attractive force holding electrons together in an atom.

Friction is the resistance to flow or movement. When we rub bodies together, the movement of electrons becomes inhibited and this can cause an orbital electron loosely held in an atom to be pulled off as the force of friction increases. This mechanism would result in a body losing electron and another readily gaining that electron as they interact. The loss and gain of electrons causes a neutral body to become charged.
