Electrons are emitted from the surface of a metal in photoelectric effect.

<h3>What is the photoelectric effect?</h3>

The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..

For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.

Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

A rock has a mass of 416 grams and when placed in a beaker of water, the level rose to 523 mL. The beaker was originally filled
vagabundo [1.1K]

Answer:

The answer is

<h2>2.55 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 416 g

volume = final volume of water - initial volume of water

volume = 523 - 360 = 163

volume = 163 mL

The density is

density =  \frac{416}{163}  \\  = 2.552147239...

We have the final answer as

<h3>2.55 g/mL</h3>

Hope this helps you

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
