Answer:

3.375moles of O₂

Explanation:

The reaction expression is given as;

                   2KClO₃ → 2KCl + 3O₂

Number of moles of KClO₃  = 2.25moles

Now;

To find the number of moles of O₂ produced we use known number of moles.

So;

                  2 mole of KClO₃ will produce 3 moles of O₂

                 2.25moles of KClO₃ will produce \frac{2.25 x 3}{2}   = 3.375moles of O₂

Compare the boiling points of alcohol, ethers and alkanes and explain one reason for the difference
scoundrel [369]

Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.

<h3>What is meant by Boiling Point ?</h3>

The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.

Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C

The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.

The OH group in  alcohol allows molecules to engage in hydrogen bonding.

Therefore Boiling point are in the order ;

Alcohol > alkane > ethers

Fiesta28 [93]

Answer:

Ice

Explanation:

The Ice would absorb heat to change the temperature from anything below 1 degree celsius in order to become liquid water. After being a liquid water it'd absorb further amount of energy in order to increase it's temperature to 100 degrees. Therefore, the Ice absorb more water

Noble gases

Explanation:

     Electronic configuration 1s²  2s²   2p⁶

 The element belongs to the group of the noble gases.

  • The noble gases have complete outer shell configuration of their atoms.
  • we can infer that the configuration above is for an element in the p-block because the last sub-level filled is the p-orbital.
  • The elements therefore belongs to the p-block
  • The block is from group 111A to O
  • Only the halogens and noble gases fits this picture from the option.
  • The outer most p-subshell have three orbitals requiring 6 electrons to fill them up.
  • This makes a complete and stable configuration.
  • The highest energy level of 2 is also made up of 8 electrons, an octet.
  • This is why we can conclude that they are noble gases.
