A few pieces of dry ice, CO2(s), at -78°C are placed in a flask that contains air at 21°C. The flask is sealed by placing an uni

nflated balloon over the mouth of the flask. As the balloon inflates, the dry ice disappears and no liquid is observed in the flask.
State the direction of heat flow that occurs between the dry ice and the air in the flask.

The dry ice absorbs heat from the air in the flask and become CO2 gas directly. So the heat flow from air to dry ice. And the CO2 gas increase the amount of the air. Though the temperature decreases, the balloon still inflates.

How many valence electrons are in Tc
mixer [17]
Tc is Technetium, and it has an atomic number of 43. Its atomic configuration is [Kr] 5s(1) 4d(5) [I'm on my phone so I can't do numbers on shoulders, pretend that 1 and 5 are on the s and d's shoulder]
The outside most ring is the 4d(5), and the d orbital can hold ten electrons.
Valence electrons are electrons, in you could say the outside ring that isn't filled, the extra ones. In this case, there are 5.

Most organic polymers are named based on the monomers used in their production. However, poly(vinyl alcohol) (PVA) is not made f
aleksandrvk [35]

Answer:

Polymerization involves the synthesis of two or more monomers to get a polymer which is usually complex.

Polyvinyl alcohol can’t be used as a monomer(raw material) for polymerization because it is very unstable under normal conditions and will rearrange molecularly to give polyvinyl acetaldehyde.
