In a pressure cooker, a lid is screwed tightly onto a pot so that the air pressure in the pot is increased. What effect, if any, will this have on the boiling point of water in the pot?The boiling point will be raised.
The boiling point will be lowered.
The boiling point will be unaffected.
None of the above.

Answers

Answer 1

Answer: A liquid boils when it's vapor pressure will be equal to the atmospheric pressure. With the lid on, increases the pressure inside the pot. As an effect, it would take a higher temperature to reach the boiling temperature.

Answer: The boiling point will be raised.

Answer 2

Answer: If a lid is screwed on tightly in a pressure cooker, the air pressure is increased. This will make the boiling point of the water to be raised.

What are the formal charges of both chlorines and iodine in icl2?

Answers

Answer:

Explanation:

Formal charge of ICl₂⁻

Formal charge = group no - ( no of non bonding electrons +no of bonds)

In I there are 7 electrons in outermost orbit . If we add one more electrons due to - ve charge on the ion , it becomes eight . This centrally placed iodine forms two single bond with two chlorine atoms on either side.

Each of chlorine atoms also contains 7 valance electrons like iodine.

So formal charge of chlorine

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 6 + 1 )

= 0

So formal charge of iodine

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 5 + 2 )

Formal charge of ICl₂⁺

In this case , central iodine will have only 6 valence electrons due to absence one electron.

So formal charge of chlorine in ICl₂⁺

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 6 + 1 )

= 0

formal charge of iodine in in ICl₂⁺

7 - ( 4 + 2)

= 1

If the system 2CO(g)+O2(g) 2CO2(g) has come to equilibrium and then more CO(g) is added,

Answers

If more CO is added the reaction will shift to the right and produce more products to maintain the equilibrium constant. This can be explained through Le Chatlier principles. I hope this helps. Let me know if anything is unclear.

How can a mixture of nails and sawdust be most efficiently separated into its component parts?

Answers

I am pretty sure that sawdust float in water so you could dump the mixture in water so that all of the sawdust float on the surface while the nails sink to the bottom.

You might also be able to use a strong magnet since nails are usually magnetic while sawdust is not.

I hope this helps. Let me know if anything is unclear or if you need a different method.

What makes an atom able to form a compound? * O different number of neutron than protons O unfilled outer electron shells O same number of protons as electrons O a positive ot negative charge of the nucleus

Answers

Answer:

same number of protons as electrons

Explanation:

The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element. ... If you change the number of electrons in an atom, you will get an ion of the element.
