Fter a radioactive atom decays, it is the same element that it was before with no measurable change in mass. Which kind of decay
Alborosie

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. the decay that is present is gamma decay because gamma decay has photons which has no mass unlike alpha and beta decay.

Which of the statements regarding alcohols and ethers are true? 1-Propanol is more likely to be a liquid at 50 °C50 °C than is m
irina [24]

Answer:

Following statements are true:

1-Propanol is more likely to be a liquid at 50 than is methoxyethane (ethyl methyl ether).

Alcohol molecules can form hydrogen bonds among themselves;ether molecules cannot

Explanation:

<u>1-Propanol is more likely to be a liquid at 50 than is methoxyethane (ethyl methyl ether). </u>

This is true

Propanol has a boiling temperature (this is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor) of 97-98 °C while methoxyethane a boiling point of 7.4 °C.

This means at 50 °C propanol is liquid but methoxyethane at 50°C is a gas.

<u>Methoxyethane (ethyl methyl ether) is more soluble in water than is 1-propanol.</u>

This false:

Propanol has a hydrogen bonding.  <u> </u>The OH on the alcohol can form a hydrogen bond (as a hydrogen acceptor and donor). Water can hydrogen bond. This means alcohol is will disolve in water. ( Remember Like dissolves like). So, when you have a molecule that can act as a donor and acceptor you end up with a much better interaction with water and end up with something that is more miscible. Ethers are only acceptors since they do not have a hydrogen attached to the oxygen. So, they can only accept a proton from water.

<u>Methoxyethane (ethyl methyl ether) is more likely to be a liquid at 50 °C50 °C than is 1-propanol</u>

This is false because propanol has a boiling temperature (this is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor) of 97-98 °C while methoxyethane a boiling point of 7.4 °C.

This means at 50 °C propanol is liquid but methoxyethane at 50°C is a gas.

<u>Alcohol molecules can form hydrogen bonds among themselves;ether molecules cannot</u>

This is true because:

Ether molecules cannot form hydrogen bonding between themselves because the oxygen atom is attached to 2 alkyl or aryl groups R-O-R, e.g diethyl ether, or Ar-O-Ar, such as diphenylether (C6H5)2O

C2H5-O-C2H5,m or dimethyl ether CH3—O-CH3. however they can between ether molecules and other molecules containing hydrogen atoms, such as alcohols, CH3OH. Any molecule with the hydrogen attached to a strongly electronegative element e.g Nitrogen or fluorine.

<u>Methoxyethane (ethyl methyl ether) has a higher boiling point than 1-propanol.</u>

This is false: Methoxyethane has a boiling point of 7.4 °C while propanol has a boiling point of 97-98 °C. This can be shown because at roomtemperature Methoxyethane is a gas but propanol is a liquid.

Mass has to do with how many particles
Ganezh [65]

The law of definite proportions agrees with Dalton atomic theory.

What is Dalton atomic theory?

It state that all matters is made of very tiny particles called atom. atoms are individual particles which can not be created or be destroyed in a chemical reactions. Atoms of given elements are identical in mass and chemical properties. Atoms of

different elements have different masses and chemical properties.

The law of definite proportions also known as proust's law ,state that a chemical compound contain the same proportion of elements by mass.this law is one of the stoichiometry .

Thus ,

This is the reason why it is agrees with dalton atomic theory.
